【SSM】Eclipse使用Maven创建Web项目+整合SSM框架

自己接触ssm框架有一段时间了，从最早的接触新版ITOO项目的（SSM/H+Dobbu zk），再到自己近期来学习到的《淘淘商城》一个ssm框架的电商项目。用过，但是还真的没有自己搭建过，一直都是用别人搭建好的。所以，从网上找了一些材料，结合自己来解决过程中的一些问题，使自己对ssm框架理解更加深了，不为分享，只是总结一下，下次有机会再搭建的时候，直接看自己的博客，省得找了！

 

一、准备环境：

maven：apache-maven-3.2.3

jdk：jdk1.8.0_25

tomcat：tomcat-6.0.37

二、配置Maven、jdk

1、Window——>Preferences——>Maven——>设置自己的Settings

2、Window——>Preferences——>Java——>Installed JREs——>Add

配置好maven之后，就可以在本地设置好的地方看到对应的Maven文件了，还有包含resp文件夹

 

三、新建Maven项目：

1、右击——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Next

 

 

2、这时候，我们就成功创建出一个Maven项目了，项目结构如下图：

 

3、右击项目，选择Properties进行一些配置：

 

       到这里，我们的Maven项目就建好了，接下来，我们来整合搭建SSM（spring MVC + Spring + Mybatis）

首先我们来配置一些整合框架所必须要的jar包，也就是来配置我们的pom文件，然后直接alt+f5，保存后，就会自动下载，存放在之前配置好的本地maven仓库中。

pox.xml配置依赖的内容：

2、在src/main/resources下添加配置文件：applicationContext.xml:

 

<?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-3.1.xsd                               http://www.springframework.org/schema/context                               http://www.springframework.org/schema/context/spring-context-3.1.xsd                               http://www.springframework.org/schema/mvc                               http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">                                      <!-- 使用注解式注入 -->         <context:annotation-config />                  <!-- 自动扫描 -->         <context:component-scan base-package="com.ssm" />                  <!-- 导入DAO配置 -->         <import resource="spring-dao.xml"/>                  <!-- 导入数据库配置 -->         <import resource="spring-db.xml"/>                  <!-- 导入数据库配置 -->         <import resource="spring-tx.xml"/>              </beans>    

 

 

配置数据库连接池：jdbc.properties

 

 

driver=com.mysql.jdbc.Driver     url=jdbc:mysql://localhost:3306/maven_ssm     username=root     password=root     #定义初始连接数     initialSize=0     #定义最大连接数     maxActive=20     #定义最大空闲     maxIdle=20     #定义最小空闲     minIdle=1     #定义最长等待时间     maxWait=60000    

 

 

配置日志：log4j.properties

 

#定义LOG输出级别     log4j.rootLogger=INFO,Console,File     #定义日志输出目的地为控制台     log4j.appender.Console=org.apache.log4j.ConsoleAppender     log4j.appender.Console.Target=System.out     #可以灵活地指定日志输出格式，下面一行是指定具体的格式     log4j.appender.Console.layout = org.apache.log4j.PatternLayout     log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n          #文件大小到达指定尺寸的时候产生一个新的文件     log4j.appender.File = org.apache.log4j.RollingFileAppender     #指定输出目录     log4j.appender.File.File = logs/ssm.log     #定义文件最大大小     log4j.appender.File.MaxFileSize = 10MB     # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志     log4j.appender.File.Threshold = ALL     log4j.appender.File.layout = org.apache.log4j.PatternLayout     log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n    

配置我们的ioc注入：spring-dao.xml

 

 

<?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-3.1.xsd                               http://www.springframework.org/schema/context                               http://www.springframework.org/schema/context/spring-context-3.1.xsd                               http://www.springframework.org/schema/mvc                               http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">                                                                   <!-- DAO接口所在包名，Spring会自动查找其下的类 -->         <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">             <!--basePackage指定要扫描的包，在此包之下的映射器都会被搜索到。              可指定多个包，包与包之间用逗号或分号分隔-->             <property name="basePackage" value="com.ssm.dao" />             <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>         </bean>                                                         </beans>    

 

 

spring-db.xml

 

<?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-3.1.xsd                               http://www.springframework.org/schema/context                               http://www.springframework.org/schema/context/spring-context-3.1.xsd                               http://www.springframework.org/schema/mvc                               http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">              <!-- 引入配置文件 -->         <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">             <property name="location" value="classpath:jdbc.properties" />         </bean>                  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">             <property name="driverClassName" value="${driver}" />             <property name="url" value="${url}" />             <property name="username" value="${username}" />             <property name="password" value="${password}" />             <!-- 初始化连接大小 -->             <property name="initialSize" value="${initialSize}"></property>             <!-- 连接池最大数量 -->             <property name="maxActive" value="${maxActive}"></property>             <!-- 连接池最大空闲 -->             <property name="maxIdle" value="${maxIdle}"></property>             <!-- 连接池最小空闲 -->             <property name="minIdle" value="${minIdle}"></property>             <!-- 获取连接最大等待时间 -->             <property name="maxWait" value="${maxWait}"></property>         </bean>              <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->         <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">             <property name="dataSource" ref="dataSource" />             <!-- 自动扫描mapping.xml文件 -->             <property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>         </bean>              </beans>    

配置spring的事务管理器：spring-tx.xml

 

 

<?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-3.1.xsd                               http://www.springframework.org/schema/context                               http://www.springframework.org/schema/context/spring-context-3.1.xsd                               http://www.springframework.org/schema/mvc                               http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">              <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->         <bean id="transactionManager"             class="org.springframework.jdbc.datasource.DataSourceTransactionManager">             <property name="dataSource" ref="dataSource" />         </bean>              </beans>    

接下来，我们来整合spring mvc：spring-mvc.xml:

 

<?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-3.1.xsd                               http://www.springframework.org/schema/context                               http://www.springframework.org/schema/context/spring-context-3.1.xsd                               http://www.springframework.org/schema/mvc                               http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">                                      <!--避免IE执行AJAX时，返回JSON出现下载文件 -->         <bean id="mappingJacksonHttpMessageConverter"             class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">             <property name="supportedMediaTypes">                 <list>                     <value>text/html;charset=UTF-8</value>                 </list>             </property>         </bean>                   <!-- 添加注解驱动 -->           <mvc:annotation-driven />         <mvc:default-servlet-handler/>                  <!-- 设置使用注解的类所在的包 -->         <context:component-scan base-package="com.ssm.controller" />                  <!-- 完成请求和注解POJO的映射 -->         <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">             <property name="messageConverters">                 <list>                     <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->                 </list>             </property>         </bean>                  <!-- 定义跳转的文件的前后缀 ，视图模式配置-->         <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">             <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->             <property name="prefix" value="/WEB-INF/jsp/" />             <property name="suffix" value=".jsp" />         </bean>                  <!-- SpringMVC上传文件时，需要配置MultipartResolver处理器-->         <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">               <!-- 默认编码 -->             <property name="defaultEncoding" value="utf-8" />               <!-- 文件大小最大值 -->             <property name="maxUploadSize" value="10485760000" />               <!-- 内存中的最大值 -->             <property name="maxInMemorySize" value="40960" />           </bean>           </beans>    

修改web.xml

 

 

<?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"         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>Archetype Created Web Application</display-name>                  <welcome-file-list>             <welcome-file>/index.jsp</welcome-file>         </welcome-file-list>                  <!-- 加载spring bean -->         <context-param>              <param-name>contextConfigLocation</param-name>             <param-value>classpath:applicationContext.xml</param-value>         </context-param>         <listener>             <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>         </listener>                  <!-- 编码过滤器 -->         <filter>             <filter-name>encodingFilter</filter-name>             <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>             <async-supported>true</async-supported>             <init-param>                 <param-name>encoding</param-name>                 <param-value>UTF-8</param-value>             </init-param>         </filter>         <filter-mapping>             <filter-name>encodingFilter</filter-name>             <url-pattern>/*</url-pattern>         </filter-mapping>                  <!-- Spring MVC servlet -->         <servlet>             <servlet-name>SpringMVC</servlet-name>             <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>             <init-param>                 <param-name>contextConfigLocation</param-name>                 <param-value>/WEB-INF/spring-mvc.xml</param-value>             </init-param>             <load-on-startup>1</load-on-startup>             <async-supported>true</async-supported>         </servlet>         <servlet-mapping>             <servlet-name>SpringMVC</servlet-name>             <url-pattern>/</url-pattern>         </servlet-mapping>              </web-app>    

 

到这里，我们的ssm框架就完成了，下面，我们来个实现：

在src/main/java下分别添加我们的dao包，service包，还有controller包.包里面添加相应的类，效果图如下：

 

 

UserController.java:

package com.ssm.controller;          import java.util.List;          import javax.annotation.Resource;     import javax.servlet.http.HttpServletRequest;          import org.springframework.stereotype.Controller;     import org.springframework.ui.Model;     import org.springframework.web.bind.annotation.RequestMapping;          import com.ssm.dto.User;     import com.ssm.service.IUserService;          @Controller     @RequestMapping("/user")     public class UserController {         @Resource         private IUserService userService;                  @RequestMapping("/userList")         public String userList(HttpServletRequest request,Model model){             List<User> uList = userService.getAllUser();             model.addAttribute("uList", uList);             return "userList";         }                  @RequestMapping("/showUser")         public String showUser(HttpServletRequest request,Model model){             int userId = Integer.parseInt(request.getParameter("id"));             User user = userService.getUserById(userId);             model.addAttribute("user", user);             return "showUser";         }                  @RequestMapping("/addUserUI")         public String addUserUI(){             return "addUser";         }                  @RequestMapping("/addUser")         public String addUser(HttpServletRequest request,Model model){             User user = new User();             user.setName(String.valueOf(request.getParameter("name")));             user.setPassword(String.valueOf(request.getParameter("password")));             user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));             userService.addUser(user);             return "redirect:/user/userList";         }     }    

 

 

IUserDao.java:

 

package com.ssm.dao;          import java.util.List;     import java.util.Map;          import com.ssm.dto.User;          public interface IUserDao {                  public User queryByPrimaryKey(Integer id);                  public List<User> queryUserByBatch(Map<String,Object> params);                  public void insertUser(User user);                  public void insertUserByBatch(List<User> list);                  public void deleteByPrimaryKey(Integer id);                  public void delteUserByBatch(Map<String,Object> params);                  public void updateByPrimaryKey(Integer id);              public List<User> getAllUser();              }    

 

 

User.java:

IUserService.java:

 

 

package com.ssm.service;          import java.util.List;          import com.ssm.dto.User;          public interface IUserService {                  public User getUserById(int userId);              public void insertUser(User user);              public void addUser(User user);              public List<User> getAllUser();     }    

UserServiceImpl.java:

package com.ssm.service.Impl;          import java.util.List;          import javax.annotation.Resource;          import org.springframework.stereotype.Service;          import com.ssm.dao.IUserDao;     import com.ssm.dto.User;     import com.ssm.service.IUserService;          @Service("userService")     public class UserServiceImpl implements IUserService {         @Resource         private IUserDao userDao;                  public User getUserById(int userId) {             return userDao.queryByPrimaryKey(userId);         }              public void insertUser(User user) {             userDao.insertUser(user);         }              public void addUser(User user) {             userDao.insertUser(user);         }              @Override         public List<User> getAllUser() {             return userDao.getAllUser();         }          }    

接下来就是我们的静态页面了jsp文件了，在WEB-INF文件夹下新建jsp文件夹，添加userinfo.jsp

 

userinfo.jsp:

 

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>     <%     String path = request.getContextPath();    String basePath=request.getSSScheme()+"://request.getServerName()"+":"+request.getServerPort+Path+     "/"%>   <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">     <html>       <head>         <base href="<%=basePath%>">                  <title>My JSP 'userinfo.jsp' starting page</title>                  <meta http-equiv="pragma" content="no-cache">         <meta http-equiv="cache-control" content="no-cache">         <meta http-equiv="expires" content="0">             <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">         <meta http-equiv="description" content="This is my page">         <!--       <link rel="stylesheet" type="text/css" href="styles.css">       -->            </head>              <body>         <form id="addUser" action="user/addUser" method="post">              userName: <input id="name" name="name" /><br/>              password: <input id="password" name="password" /><br/>             <input type="submit" value="添加新用户"/>          </form>       </body>     </html>     

 

 

哦,忘记配置tomcat，配置一下tomcat，然后部署发布项目，进行测试

到此，框架成

 

总结：    真心知道用maven之后，我们大框架真的方便多了，最起码不用个顶个的去找jar包，然后逐一的 导入，只需要在pom文件里面配置一下依赖，就好了。虽然说比较简单，可是可能是自己没有动手弄过 吧，期间除了各种各样的错，或者说是失误，但是，总之，耗时一天半，总算是通了，这也是收获， 加油吧，少（qing）年。
