1、创建项目
2、完善Java目录结构,如果生成有,就可以跳过这一步
2.1、创建java目录结构
2.2、改变目录结构
3、添加框架所需要的依赖(只拿有用的配置,不要整个都拿过去)

</project>
4、在resources目录下添加配置文件(没有此目录请自行创建,且改变目录结构,和上面一样)
5、mybatis配置文件 mybatis-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><!-- 给实体类起别名 --><typeAliases ><package name="xuan.entity"/></typeAliases></configuration>
6、Spring核心配置文件 applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd"><!-- 加载数据库连接信息配置文件 --><context:property-placeholder location="classpath:db.properties" /><!--druid连接池 --><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"><property name="driverClassName" value="${druid.driver}"/><property name="url" value="${druid.url}"/><property name="username" value="${druid.username}"/><property name="password" value="${druid.password}"/></bean><!-- 配置Mybatis工厂 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="configLocation" value="classpath:mybatis-config.xml" /></bean><!-- Mapper动态代理开发 扫包 给定包下的接口文件名和映射文件名必须相同 创建接口的实现类--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="xuan.mapper" /></bean><!-- 开启事务 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 事务注解驱动--><tx:annotation-driven /><context:component-scan base-package="xuan.service"/>
</beans>
7、springmvc配置文件 springmvc.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:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- SpringMVC使用<mvc:annotation-driven>自动加载RequestMappingHandlerMapping和RequestMappingHandlerAdapter --><mvc:annotation-driven /><!-- 启动注解 --><!-- 配置扫描注解 @Controller @Service --><context:component-scan base-package="xuan.controller" /><!-- 配置静态资源映射 --><!--<mvc:resources location="/js/" mapping="/js/**"/><mvc:resources location="/css/" mapping="/css/**"/><mvc:resources location="/imgs/" mapping="/imgs/**"/><mvc:resources location="/font/" mapping="/font/**"/>--><!-- 配置视图解析器--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- 配置逻辑视图的前缀 --><property name="prefix" value="/WEB-INF/jsp/" /><!-- 配置逻辑视图的后缀 --><property name="suffix" value=".jsp" /></bean>
</beans>
9、数据库配置文件
druid.driver=com.mysql.jdbc.Driver
druid.url=jdbc:mysql://localhost:3306/xuan?characterEncoding=utf-8
druid.username=root
druid.password=root
10、配置web.xml文件
<!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>Archetype Created Web Application</display-name><!-- 指定spring核心配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!-- 处理POST提交乱码问题 --><filter><filter-name>encoding</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>encoding</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- spring监听器 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置前端控制器 --><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 指定配置文件位置和名称 如果不设置,默认找/WEB-INF/<servlet-name>-servlet.xml --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
</web-app>
11、完善目录结构,创建实体类,dao层,service层,controller层,目录结构如下
12、配置tomcat运行
13、数据库数据如下
14、启动Tomcat,访问地址 http://localhost:1314/ssm_war/GetAll ,出现下面效果,表示成功
