# 我只说重点   按照我的步骤环境就搭建好了 #

第一步：WEB配置文件

<?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\_2\_5.xsd" id="WebApp\_ID" version="2.5">  
  <display-name>SSM</display-name>  
  <welcome-file-list>  
    <welcome-file>index.html</welcome-file>  
    <welcome-file>index.htm</welcome-file>  
    <welcome-file>index.jsp</welcome-file>  
    <welcome-file>default.html</welcome-file>  
    <welcome-file>default.htm</welcome-file>  
    <welcome-file>default.jsp</welcome-file>  
  </welcome-file-list>  
   
    
     <context-param>  
          <param-name>contextConfigLocation</param-name>  
          <param-value>classpath:springApplicationContext.xml</param-value>  
     </context-param>  
     <listener>  
      <listener-class>org.springframework.web.context.ContextLoaderListener  
     </listener-class>  
        </listener>

<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-servlet.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>  
      
      
      
      
    <filter>  
        <filter-name>ending</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>ending</filter-name>  
        <url-pattern>/\*</url-pattern>  
    </filter-mapping>

</web-app>

第二步：springMVC

<?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" xmlns:aop="http://www.springframework.org/schema/aop"  
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd  
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

<context:component-scan base-package="com.hxx.ssm.controller,com.hxx.ssm.service" />  
      
    <mvc:annotation-driven />  
    <mvc:default-servlet-handler/>  
      
    <bean id="viewResolver"  
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/" />  
        <property name="suffix" value=".jsp"></property>  
    </bean>

</beans>

第三步：mybatis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="com.hxx.ssm.pojo.SSMUser" />  
    </typeAliases>  
</configuration>

第四步： Sql语句配置    遗漏：<mapper namespace="com.hxx.ssm.dao.SSMDao">  命名空间一定要写dao的全路径

<?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="com.hxx.ssm.dao.SSMDao">  
      
    <select id="login" resultType="com.hxx.ssm.pojo.SSMUser">  
        select \* from usa  
    </select>  
      
    <delete id="dec" parameterType="int">  
        delete from usa where uid =  
        \#\{uid\}  
    </delete>

</mapper>

第五步：spring管理

<?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" xmlns:tx="http://www.springframework.org/schema/tx"  
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

<context:component-scan base-package="com.hxx.ssm">  
    </context:component-scan>

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

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">  
        <property name="driverClass" value="$\{db.driver\}"></property>  
        <property name="jdbcUrl" value="$\{db.url\}"></property>  
        <property name="user" value="$\{db.username\}"></property>  
        <property name="password" value="$\{db.password\}"></property>

</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
          
        <property name="dataSource" ref="dataSource" />  
          
        <property name="mapperLocations" value="classpath:com/hxx/ssm/dao/SSMDao.xml" />  
          
        <property name="configLocation" value="classpath:mybatis-confing.xml" />  
          
    </bean>  
      
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
          
        <property name="basePackage" value="com.hxx.ssm.dao" />  
          
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />  
    </bean>  
      
      
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
    <property name="dataSource" ref="dataSource"></property>  
      
    </bean>  
   <tx:annotation-driven transaction-manager="transactionManager"/>      
</beans>
