1、创建maven web工程
创建完成后，项目结构如下
2、项目配置文件
在pom.xml中添加SSM框架相关jar包的依赖关系，pom.xml代码如下
<?xml version="1.0" encoding="UTF-8"?> <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

在main下创建resources文件夹和java文件夹
在java文件夹下创建包结构
在resources文件夹下创建mybatis、spring和springmvc文件夹，以及jdbc.properties、log4j.properties文件
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf-8 jdbc.username=root jdbc.password=root
log4j.properties
log4j.rootLogger=DEBUG,A1 log4j.appender.A1=org.apache.log4j.ConsoleAppender log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n
在mybatis文件夹下创建SqlMapConfig.xml文件，并给出内容
<?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>
<!--分页插件-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<property name="dialect" value="mysql"/>
</plugin>
</plugins>
</configuration>
在spring文件夹下创建applicationContext-dao.xml、applicationContext-service.xml、applicationContext-trans.xml三个文件，分别给出内容
applicationContext-dao.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" 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-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <!-- 数据库连接池 --> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 数据库连接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <property name="driverClassName" value="${jdbc.driver}"/> <property name="maxActive" value="10"/> <property name="minIdle" value="5"/> </bean> <!-- 让Spring管理sqlSessionFactory 使用Mybatis和Spring整合包中的 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 数据库连接池 --> <property name="dataSource" ref="dataSource"/> <!-- 加载Mybatis全局配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"/> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.zhuangxp.dao"/> </bean> </beans>

在springmvc下面创建springmvc.xml文件
<?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: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-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> <!--扫描@Controller注解--> <mvc:annotation-driven/> <context:component-scan base-package="cn.zhuangxp.controller"/> <!--SpringMVC视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 文件上传解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 设定默认编码 --> <property name="defaultEncoding" value="UTF-8"></property> <!-- 设定文件上传的最大值5MB，5*1024*1024 --> <property name="maxUploadSize" value="5242880"></property> </bean> <!--配置资源映射--> <!-- /会拦截搜索资源，包括静态资源 --> <!--<mvc:resources mapping="/resources/**" location="/resources/"/>--> </beans>
web.xml配置
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>ssm-demo</display-name> <!-- 加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 解决POST乱码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- SpringMVC前端控制器 --> <servlet> <servlet-name>ssm-demo</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- contextConfigLocation不是必须的，如果不配置，SpringMVC的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!--"/"拦截所有请求--> <servlet-mapping> <servlet-name>ssm-demo</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
3、测试
controller
@Controller public class TestController { @Autowired public TestService testService; @GetMapping("/getNow") @ResponseBody public String test(){ String now = testService.getNow(); return now; } }
service接口
public interface TestService { public String getNow(); }
service实现类
@Service public class TestServiceImpl implements TestService { @Autowired public TestMapper testMapper; @Override public String getNow() { return testMapper.getNow(); } }
mapper接口
public interface TestMapper { public String getNow(); }
mapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.zhuangxp.dao.TestMapper">
<select id="getNow" resultType="java.lang.String">
select now()
</select>
</mapper>
配置tomcat,启动项目，访问
http://localhost:8080/getNow
