本文是基于Maven工程实现SSM整合，主要是通过XML实现三大框架的整合，可能有的小伙伴会说XML早就过时了，现在人们都使用注解开发，但是不是这么认为，我个人觉得你XML 整合会了，注解能不会吗？ 开干！！！！
SSM整合总体思路
Spring和MyBatis整合
整合JAR包
<dependencies> <!-- Spring依赖 --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-orm --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>4.3.2.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.3.2.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.aspectj/aspectjweaver --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.2</version> </dependency> <!-- https://mvnrepository.com/artifact/cglib/cglib --> <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>2.2</version> </dependency> <!-- MySQL驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-Java</artifactId> <version>5.1.3</version> </dependency> <!-- 数据源 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.31</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> <!-- MyBatis与Spring整合 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 日志 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.7</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.7</version> </dependency> <!-- Spring进行JSON数据转换依赖 --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.2</version> </dependency> <!-- JSTL标签库 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- junit测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- 引入Servlet容器中相关依赖 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <!-- JSP页面使用的依赖 --> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1.3-b06</version> <scope>provided</scope> </dependency> </dependencies>创建Spring的配置文件
- spring-persist-mybatis.xml ---数据源相关的配置
- spring-persist-tx.xml ---事务相关的配置
- spring-web-mvc.xml ---SpringMvc相关的配资
创建jdbc.properties
jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3307/crowdfunding?useUnicode=true&characterEncoding=utf8jdbc.username=rootjdbc.password=123456创建log4j.properties
log4j.rootLogger=DEBUG,myConsolelog4j.appender.myConsole=org.apache.log4j.ConsoleAppenderlog4j.appender.myConsole.Target=System.outlog4j.appender.myConsole.layout=org.apache.log4j.PatternLayoutlog4j.appender.myConsole.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n配置数据源
在配置文件spring-persist-mybatis.xml，分为两步：加载外部的属性文件，配置数据源
<!--加载外部的属性文件--> <context:property-placeholder location="classpath:db.properties"></context:property-placeholder> <!--配置数据源--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="username" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> <property name="url" value="${jdbc.url}"></property> <property name="driverClassName" value="${jdbc.driver}"></property> </bean>数据源测试类
@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations= {"classpath:/spring/spring-persist-mybatis.xml"})public class AtcrowFundingAdminTest { @Autowired public DataSource dataSource; @Test public void DataSourceTest() throws Exception{ System.out.println("数据源："+dataSource.getConnection()); }} 创建MyBatis全局配置文件
配置 mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration> <!-- 配置全局属性 --> <settings> <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 --> <setting name="useGeneratedKeys" value="true" /> <!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings></configuration>配置SqlSessionFactoryBean
在配置文件：spring-persist-mybatis.xml，分为两步：配置SqlSessionFactoryBean，配置mybatis 的包扫描器
<!--配置SqlSessionFactoryBean--> <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <!--装配数据源--> <property name="dataSource" ref="dataSource"></property> <!--mybatis配置文件所在的位置--> <property name="configLocation" value="classpath:/mybatis/mybatis-config.xml"></property> <!--配置mapper所在的文件位置--> <property name="mapperLocations" value="classpath:/mybatis/mapper/*Mapper.xml"></property> </bean> <!--配置mybatis 的包扫描器--> <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--配置mapper所在的包--> <property name="basePackage" value="com.zfcoding.dao"></property> </bean>到这里spring-persist-mybatis.xml配置文件已经完成了。

配置spring-web-mvc.xml
开启注解驱动，配置视图解析器

@Controller@RequestMapping("admin")public class AdminController { @Autowired public AdminService adminService; @RequestMapping("/findall") public String findAll(Model model) { List<AdminBean> list = adminService.findAllAdmin(); model.addAttribute("list", list); return "admin"; }}请求路径：http://localhost:8080/ssm_war_exploded/admin/findall.action
页面响应
AdminBean{id=1, loginAcct='admin', userPswd='123', userName='你好', email='', createTime='null'}
到此SSM 基本功能的整合已经完成了。
