1. 导包

2. 在web.xml文件中配置spring和spring的配置信息

<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:SpringMVC.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMvc</servlet-name>
        
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

    
    <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

application.xml的配置

<--以上是spring的约束，下面才是配置信息-->

<context:property-placeholder location="classpath:db.properties">

</context:property-placeholder>

<--下面这个是扫描文件中的信息通过键值名= 键值的方式书写 -->

jdbc.driver =com.mysql.jdbc.Driver
jdbc.url =jdbc:mysql://localhost:3306/mybatis01
jdbc.username=root
jdbc.password=root

<-- 以上信息如果有扫描引用可通过表达式获得对应的值-->

<bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<--以下四条都是通过ognl表达式拿到上面扫描文件中的值，即连接数据库的信息-->
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>
    
    <bean name="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
    </bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.hd.mapper"></property>
    </bean>
    
    <context:component-scan base-package="cn.hd"></context:component-scan>
    
    <bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>

<--配置要在哪些方法加入事务操作 add*表示以add开头的方法都可加上操作-->
<tx:method name="add*" read-only="false" propagation="REQUIRED" isolation="DEFAULT"/>

<-- 设置只读默认的是不开启的查询操作可开启不需事务-->
            <tx:method name="delete*" read-only="false" propagation="REQUIRED" isolation="DEFAULT"/>
            <tx:method name="update*" read-only="false" propagation="REQUIRED" isolation="DEFAULT"/>
            <tx:method name="get*" read-only="true" propagation="REQUIRED" isolation="DEFAULT"/>
        </tx:attributes>
    </tx:advice>
    
    <aop:config>

<-- 配置在执行哪些方法前执行事务操作-->
        <aop:pointcut id="txPt" expression="execution(* cn.hd.service.impl.*ServiceImpl.*(..))"></aop:pointcut>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPt"></aop:advisor>
    </aop:config>
</beans>

MyBatis的配置

<?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>
        <typeAliases>
            <package name="cn.hd.entity"></package>
            <package name="cn.hd.queryVo"></package>
        </typeAliases>

<-- 配置环境可配置多个-->
<environments default="development">
<environment id="development">

<mappers>

<mapper resource="cn/hd/mapper/UserMapper.xml"></mapper>
</mappers>
</configuration>

SpringMvc的配置

<?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-4.0.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
   <-- 扫描指定包下的注解-->
    <context:component-scan base-package="cn.hd.controller"></context:component-scan>
        
        <mvc:annotation-driven>
            <mvc:message-converters>
                <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
                <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
            </mvc:message-converters>
        </mvc:annotation-driven>
</beans>

项目的结构目录

测试:

@Controller
public class UserController {
    @Resource(name = "userServiceImpl")
    private UserService userService;
    @RequestMapping(value = "login.action")
    public ModelAndView login(){
        User user = userService.getUserById(10);
        System.out.println(user);
        ModelAndView mav = new ModelAndView();
        mav.setViewName("/index.jsp");
        return mav;
    }
}
