maven搭建ssm项目

一 准备工作

框架的版本：

Spring 4.0.2 RELEASE Spring MVC 4.0.2 RELEASE MyBatis 3.2.6 前提搭建好maven环境，用eclipse新建一个maven项目。 新建maven: http://blog.csdn.net/qq_22860341/article/details/72367922 新建的maven结构:

二 ,在pom.xml中引入jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.demo</groupId> <artifactId>maven_ssm</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>maven01 Maven Webap</name> <properties> <!-- spring版本号 --> <spring.version>4.0.2.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <!-- 表示开发的时候引入，发布的时候不会加载此包 --> <scope>test</scope> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</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-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 导入java ee jar 包 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <!-- 导入Mysql数据库链接jar包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.36</version> </dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <!-- 格式化对象，方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> </dependencies> <build> <finalName>maven01</finalName> <plugins> <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.2.8.v20150217</version> <configuration> <httpConnector> <port>80</port> </httpConnector> <stopKey>shutdown</stopKey> <stopPort>9966</stopPort> </configuration> </plugin> </plugins> </build> </project>

三，新建开发的包

在src/main/java下新建package:

新建配置文件

配置文件包含五个： spring-mvc.xml，spring-mybatis.xml，web.xml，jdbc.properties，log4j.properties。

1，配置spring-mvc.xml，主要配置 扫描控制器，视图模式，注解的启动。 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"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="com.controller" /> <!-- 拦截所有springmvc的url！ --> <!-- <mvc:interceptors> <bean class="com.interceptor.SessionInterceptor"></bean> </mvc:interceptors> --> <!-- 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/plain;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> <mvc:annotation-driven /> <!-- 支持spring3.0新的mvc注解 --> <!-- 启动Spring MVC的注解功能，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> <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> <!-- <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="cacheSeconds" value="0" /> <property name="messageConverters"> <list> <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> </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> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding"> <value>UTF-8</value> </property> <property name="maxUploadSize"> <value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 --> </property> <property name="maxInMemorySize"> <value>4096</value> </property> </bean> </beans>

2,配置spring-mybatis.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"> <!-- 自动扫描 --> <context:component-scan base-package="com" /> <!-- 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/mapping/*.xml"></property> </bean> <!-- Sql Session --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg index="0" ref="sqlSessionFactory" /> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (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>

3,配置jdbc.properties，用的mysql

driver=com.mysql.jdbc.Driver url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true 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

4，配置log4j.properties

#定义LOG输出级别 log4j.rootLogger=DEBUG,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 = INFO log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n ###显示SQL语句部分 log4j.logger.com.ibatis=DEBUG log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG log4j.logger.java.sql.Connection=DEBUG log4j.logger.java.sql.Statement=DEBUG log4j.logger.java.sql.PreparedStatement=DEBUG

5，web.xml配置

<?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>Audit</display-name> <!-- 初始化字符集控制器 --> <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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- SpringMVC核心控制器 --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml,classpath:spring-mybatis.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>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> <welcome-file>/login.html</welcome-file> </welcome-file-list> <!-- session失效时间设置 --> <session-config> <session-timeout>-1</session-timeout> </session-config> </web-app>

6,新建数据库，表test,字段id自增长，username,password;

7，到此配置就配好了，可以写代码测试了。我这里配置mybatis generatorConfig.xml自动生成代码，免得以后表多自己写实体对象entity，Mapper基本结构文件，与Mapper对应的dao基本接口文件。 在你的maven存放jar的位置，或者自己下载一个引用 mybatis-generator-core-1.3.2.jar配置文件要引用。 generatorConfig.xml：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!-- 引入mysql-connector-java-5.1.30.jar位置 --> <classPathEntry location="E:/maven/repository/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar" /> <!-- 是否去除自动生成的注释 true：是 ： false:否 --> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressAllComments" value="true" /> </commentGenerator> <!-- 数据库连接 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/test" userId="root" password="root"> </jdbcConnection> <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal --> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- 生成model模型，对应的包路径，以及文件存放路径(targetProject)，targetProject可以指定具体的路径 也可以使用“MAVEN”来自动生成，这样生成的代码会在target/generatord-source目录下 --> <javaModelGenerator targetPackage="com.entity" targetProject="E:\workspace\maven_ssm\src\main\java"> <property name="enableSubPackages" value="true" /> <!-- 从数据库返回的值被清理前后的空格 --> <property name="trimStrings" value="true" /> </javaModelGenerator> <!--对应的mapper.xml文件 --> <sqlMapGenerator targetPackage="com.mapping" targetProject="E:\workspace\maven_ssm\src\main\java"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 对应的Mapper接口类文件 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.dao" targetProject="E:\workspace\maven_ssm\src\main\java"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 生成那些表，tableName对应数据库表，domainObjectName对应实体类名 --> <table tableName="test" domainObjectName="Test" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>

在pom.xml配置：

<build> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> </plugin> </plugins> </build>

运行方法： 在eclipse 中，选择pom.xml文件，击右键先择Run AS——>Maven Build… ——>在Goals框中输入：mybatis-generator:generate 运行结果：

若配置自动生成diamante不对，请参考： http://blog.csdn.net/qq_22860341/article/details/72638725

8.测试方法，新增用户 ITestService.java:

package com.service; import com.entity.Test; public interface ITestService { int insert(Test record); }

TestServiceImpl:

package com.service.impl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.dao.TestMapper; import com.entity.Test; import com.service.ITestService; @Service("testService") public class TestServiceImpl implements ITestService{ @Autowired private TestMapper testMapperdao; @Override public int insert(Test record) { return testMapperdao.insert(record); } }

TestController:

package com.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.entity.Test; import com.service.ITestService; @Controller @RequestMapping("/user") public class TestController { @Resource private ITestService testService; @RequestMapping("test") public String addUser(Test record){ int num = testService.insert(record); System.out.println(num); return "success"; } }

index.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; String exitMsg = (String)request.getParameter("exitMsg"); %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>test</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <script src="js/jquery-2.1.0.min.js" type="text/javascript"></script> <script src="js/jquery-2.1.0.js" type="text/javascript"></script> </head> <script type="text/javascript"> jQuery(document).ready(function(){ }); function insert(){ $.ajax({ type : "POST", url : 'user/test.do', dataType:'json', cache:false, async: false, data:{ username:$("#username").val(), password:$("#password").val() }, success : function(data) { },error:function(data){ } }); } </script> <body> 用户名：<input type="text" id="username" value=""/> 密码： <input type="password" id="password" value=""/> <button onclick="insert()">注册</button> </body> </html>

9 ，最终结构：
