一、创建Hessian的Server

1.1创建web项目HessionSer，其pom.xml配置如下：

[java]  view plain  copy <properties>           <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>           <argLine>-Dfile.encoding=UTF-8</argLine>           <spring.version>4.1.6.RELEASE</spring.version>       </properties>       <dependencies>           <dependency>               <groupId>javax.servlet</groupId>               <artifactId>jstl</artifactId>               <version>1.2</version>               <scope>provided</scope>           </dependency>           <dependency>               <groupId>javax.servlet.jsp</groupId>               <artifactId>jsp-api</artifactId>               <version>2.1</version>               <scope>provided</scope>           </dependency>           <dependency>               <groupId>org.glassfish</groupId>               <artifactId>javax.annotation</artifactId>               <version>3.0.1</version>           </dependency>           <dependency>               <groupId>org.glassfish</groupId>               <artifactId>javax.ejb</artifactId>               <version>3.0.1</version>           </dependency>           <dependency>               <groupId>org.jboss.weld</groupId>               <artifactId>weld-osgi-bundle</artifactId>               <version>1.0.1-SP3</version>           </dependency>           <dependency>               <groupId>org.glassfish</groupId>               <artifactId>javax.servlet</artifactId>               <version>3.0.1</version>           </dependency>           <dependency>               <groupId>com.caucho</groupId>               <artifactId>hessian</artifactId>               <version>4.0.38</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-test</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-core</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-aop</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-webmvc</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-jdbc</artifactId>               <version>${spring.version}</version>           </dependency>       </dependencies>  

1.2.配置web.xml

[java]  view plain  copy <?xml version="1.0" encoding="UTF-8"?>   <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">     <display-name></display-name>     <welcome-file-list>       <welcome-file>index.jsp</welcome-file>     </welcome-file-list>     <context-param>       <param-name>contextConfigLocation</param-name>       <param-value>               classpath*:spring*.xml           </param-value>     </context-param>     <listener>       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>     <servlet>       <servlet-name>remoting</servlet-name>       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>       <init-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath*:remoting-servlet.xml</param-value>       </init-param>       <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>       <servlet-name>remoting</servlet-name>       <url-pattern>/remoting/*</url-pattern>     </servlet-mapping>   </web-app>  

1.3.Hessian的配置文件:remoting-servlet.xml。

因为web.xml里的servlet为remoting，默认会查找servlet的name-servlet.xml的文件，即remoting-servlet.xml，而上面配置里通过contextConfigLocation去查找，所以，此时该配置文件名字可以任意设置。内容如下： [java]  view plain  copy <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">   <beans>       <!-- 接口的具体实现类 -->       <!-- <bean id="loginTestInterfa" class="com.cn.wddqz.manage.impl.LoginTestImpl" /> -->       <!-- 使用Spring的HessianServie做代理 -->       <bean name="/loginTestInterfa"       class="org.springframework.remoting.caucho.HessianServiceExporter">           <!-- service引用具体的实现实体Bean-->           <property name="service" ref="loginTestInterfa" />           <property name="serviceInterface" value="com.cn.wddqz.manage.LoginTestInterfa" />       </bean>      </beans>  

1.4.因为用到spring注解，所以配置spring-servlet.xml:

[java]  view plain  copy <?xml version="1.0" encoding="UTF-8"?>   <beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:mvc="http://www.springframework.org/schema/mvc"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd             http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd             http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd             http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd          http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">          <!-- 设置使用注解的类所在的jar包 -->       <context:component-scan base-package="com.cn.wddqz"></context:component-scan>          <!-- 完成请求和注解POJO的映射 -->       <bean           class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />       <bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter"/>   </beans>  

1.5.定义一个接口

[java]  view plain  copy package com.cn.wddqz.manage;      /**   * Hessian Server的接口需要暴露给client使用   * 类名称：LoginTestInterfa   * 类描述：   * 创建人：wodediqizhang@163.com   * 修改时间：2016-6-20 下午4:22:02   * Modification History:   * =============================================================================   *   Author         Date          Description   *   ------------ ---------- ---------------------------------------------------   *   ghb            2016-6-20        创建文档    * =============================================================================   * @version 1.0.0   *   */   public interface LoginTestInterfa {          public String qualifyInfo(String name,String mail) ;   }  

1.6.接口的实现:

[java]  view plain  copy package com.cn.wddqz.manage.impl;      import com.cn.wddqz.manage.LoginTestInterfa;   import org.springframework.stereotype.Service;   /**   * Hessian Server的接口实现，client调用接口，会在这里进行业务处理   * 类名称：LoginTestImpl   * 类描述：   * 创建人：wodediqizhang@163.com   * 修改时间：2016-6-20 下午4:22:44   * Modification History:   * =============================================================================   *   Author         Date          Description   *   ------------ ---------- ---------------------------------------------------   *   ghb            2016-6-20        创建文档    * =============================================================================   * @version 1.0.0   *   */   @Service("loginTestInterfa")   public class LoginTestImpl implements LoginTestInterfa {          @Override       public String qualifyInfo(String name, String mail) {           System.out.println("Hessian Server 接口调用");           return "名字：["+name+"],邮箱：["+mail+"]";       }   }   此时，Hessian的Server端已经完成了。因为Hessian是接口暴露，所以将HessianSer的接口导出为jar，提供给HessianCli使用。

二、创建Hessian的Client

2.1.pom.xml加载jar包:

[java]  view plain  copy <properties>           <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>           <argLine>-Dfile.encoding=UTF-8</argLine>           <spring.version>4.1.6.RELEASE</spring.version>       </properties>       <dependencies>           <dependency>               <groupId>javax.servlet</groupId>               <artifactId>jstl</artifactId>               <version>1.2</version>               <scope>provided</scope>           </dependency>           <dependency>               <groupId>javax.servlet.jsp</groupId>               <artifactId>jsp-api</artifactId>               <version>2.1</version>               <scope>provided</scope>           </dependency>           <dependency>               <groupId>org.glassfish</groupId>               <artifactId>javax.annotation</artifactId>               <version>3.0.1</version>           </dependency>           <dependency>               <groupId>org.glassfish</groupId>               <artifactId>javax.ejb</artifactId>               <version>3.0.1</version>           </dependency>           <dependency>               <groupId>org.jboss.weld</groupId>               <artifactId>weld-osgi-bundle</artifactId>               <version>1.0.1-SP3</version>           </dependency>           <dependency>               <groupId>org.glassfish</groupId>               <artifactId>javax.servlet</artifactId>               <version>3.0.1</version>           </dependency>           <dependency>               <groupId>com.caucho</groupId>               <artifactId>hessian</artifactId>               <version>4.0.38</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-test</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-core</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-aop</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-webmvc</artifactId>               <version>${spring.version}</version>           </dependency>           <dependency>               <groupId>org.springframework</groupId>               <artifactId>spring-jdbc</artifactId>               <version>${spring.version}</version>           </dependency>              <dependency>               <groupId>hessianSer</groupId>               <artifactId>hessianSer</artifactId>               <version>0.0.1-SNAPSHOT</version>           </dependency><pre name="code" class="java"></dependencies>  

2.2.配置web.xml

[java]  view plain  copy <?xml version="1.0" encoding="UTF-8"?>   <web-app version="3.0"        xmlns="http://java.sun.com/xml/ns/javaee"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">     <display-name></display-name>      <welcome-file-list>       <welcome-file>index.jsp</welcome-file>     </welcome-file-list>     <context-param>           <param-name>contextConfigLocation</param-name>           <param-value>               classpath*:context.xml           </param-value>       </context-param>       <!-- Start 配置上下文载入器 -->       <!-- 上下文载入器载入除DispatcherServlet载入的配置文件之外的其它上下文配置文件 -->       <servlet>           <servlet-name>spring</servlet-name>           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>           <!-- 可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml                <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value>                 默认 </init-param> -->           <init-param>               <param-name>contextConfigLocation</param-name>               <param-value>classpath*:spring-servlet.xml</param-value>           </init-param>           <load-on-startup>1</load-on-startup>       </servlet>          <servlet-mapping>           <servlet-name>spring</servlet-name>           <url-pattern>/</url-pattern>       </servlet-mapping>              <!-- 最常用的上下文载入器是一个Servlet监听器，其名称为ContextLoaderListener -->       <listener>           <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>       </listener>       <!-- End 配置上下文载入器 -->   </web-app>  

2.3.context.xml，客户端关于Hessian的配置：

[java]  view plain  copy <?xml version="1.0" encoding="UTF-8"?>   <beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">        <bean           class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">           <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />           <property name="ignoreResourceNotFound" value="true" />           <property name="locations">               <list>                   <value>classpath:hessian.properties</value>               </list>           </property>       </bean>       <!--客户端Hessian代理工厂Bean-->       <bean id="loginTestInterfa"           class="org.springframework.remoting.caucho.HessianProxyFactoryBean">           <!--这是因为接口中出现方法重载，在调用时，服务器端会跑出异常 。在整合spring中，在客户端的配置里面加上如下代码可以解决：-->           <property name="overloadEnabled" value="true" />           <!--请求代理Servlet路径：-->           <property name="serviceUrl" value="${hessian.url}loginTestInterfa" />           <!--接口定义：-->           <property name="serviceInterface"               value="com.cn.wddqz.manage.LoginTestInterfa" />       </bean>       </beans>  

2.4.hessian.properties配置Hessian链接，内容如下：

[java]  view plain  copy #配置文件   hessian.url=http\://localhost\:8080/HessianSer/remoting/  

2.5.servlet配置文件spring-servlet.xml：

[java]  view plain  copy <?xml version="1.0" encoding="UTF-8"?>   <beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:mvc="http://www.springframework.org/schema/mvc"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd             http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd             http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd             http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd          http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">          <!-- 设置使用注解的类所在的jar包 -->       <context:component-scan base-package="com.cn.wddqz.web"></context:component-scan>          <!-- 完成请求和注解POJO的映射 -->       <bean           class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />           <!-- 定义JSP -->        <!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">           <property name="prefix" value="/WEB-INF/views/" />           <property name="suffix" value=".jsp" />       </bean>   </beans>  

2.6.写个简单的jsp，index.jsp:

[java]  view plain  copy <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>   <%   String path = request.getContextPath();   String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";   %>      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">   <html>     <head>       <base href="<%=basePath%>">       <title>测试Hessian</title>     </head>            <body>       <div style="TEXT-ALIGN: center;MARGIN-RIGHT: auto; MARGIN-LEFT: auto; ">           <form action="login" method="post">               <div>                   <label for="name">姓名:</label> <input class="easyui-validatebox"                       type="text" name="name" data-options="required:true" />               </div>               <div>                   <label for="email">邮箱:</label> <input class="easyui-validatebox"                       type="text" name="email" data-options="validType:'email'" />               </div>               <div>                   <button type="submit">登录</button>               </div>           </form>       </div>     </body>   </html>  

2.7.IndexController调用hessian接口

[java]  view plain  copy package com.cn.wddqz.web;      import javax.servlet.http.HttpServletRequest;      import org.springframework.beans.factory.annotation.Autowired;   import org.springframework.stereotype.Controller;   import org.springframework.web.bind.annotation.RequestMapping;   import org.springframework.web.servlet.ModelAndView;      import com.cn.wddqz.manage.LoginTestInterfa;      /**   * 通过Controller调用hessian接口   * 类名称：IndexController   * 类描述：   * 创建人：wodediqizhang@163.com   * 修改时间：2016-6-20 下午4:22:02   * Modification History:   * =============================================================================   *   Author         Date          Description   *   ------------ ---------- ---------------------------------------------------   *   ghb            2016-6-20        创建文档    * =============================================================================   * @version 1.0.0   *   */   @Controller   public class IndexController {          @Autowired       private LoginTestInterfa loginTestInterfa;       @RequestMapping("/login")       public ModelAndView indexView(HttpServletRequest request) {           String name = request.getParameter("name");           String email = request.getParameter("email");           String loginInfo = loginTestInterfa.qualifyInfo(name,email);           System.out.println("loginInfo="+loginInfo);           ModelAndView mv = new ModelAndView();           mv.addObject("message", loginInfo);           return mv;       }   }  

2.8.login.jsp显示调用接口之后在页面上展示message数据：

[java]  view plain  copy <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>   <%   String path = request.getContextPath();   String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";   %>      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">   <html>     <head>       <base href="<%=basePath%>">              <title>显示内容</title>     </head>          <body>      ${message };     </body>   </html>  

2.9.将HessianSer导出的jar包导出到本地，然后通过myeclipse导入到maven库里面。在HessianCli的pom.xml配置jar包即可。这样子方便以后HessianSer的接口增多时，只需要将接口导出，然后替换maven库中的jar包就能完成项目更新而不需要在修改client端的配置。

此时HessianCli就配置完成了。

三、测试

    访问http://127.0.0.1:8080/HessianCli/，得到如下界面： 点击登录，返回到login页面， 此时，测试已完成。
