idea使用maven搭建SSM项目

搭建的过程同使用maven搭建springMVC项目，

　　如有疑问，请参考我的上一篇文章：http://www.cnblogs.com/wugc/p/6588720.html

1、基本的目录结构

2、几个文件的基础配置

（1）web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">


    <!--设置字符集-->
    <filter>
        <filter-name>characterEncoding</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>characterEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


    <!-- 加载spring配置文件 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:beans.xml</param-value>
    </context-param>

    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 默认加载方式
               默认加载必须规范：
               * 文件命名：servlet-name-servlet.xml====springmvc-servlet.xml
               * 路径规范：必须在WEB-INF目录下面
         -->
        <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>*.do</url-pattern>
    </servlet-mapping>


    <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>
</web-app>

（2）spring的配置文件

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.2.xsd


      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.2.xsd
      http://www.springframework.org/schema/aop
      http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
      http://www.springframework.org/schema/tx
      http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
    <!--开启注解扫描-->
    <context:component-scan base-package="com.shuyun"></context:component-scan>
    <!-- 第一步：配置数据源 -->
    <!--1.1 加载属性文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!--1.2获取文件中的属性-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>

    </bean>

    <!-- 第二步：创建sqlSessionFactory。生产sqlSession -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
    </bean>
    <!-- 配置mybatis接口代理开发
        * 接口类名和映射文件必须同名
        *　接口类和映射文件必须在同一个目录　下
        * 映射文件namespace名字必须是接口的全类路径名
        *　接口的方法名必须和映射Statement的ｉｄ一致
     -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.shuyun.mybatis.mapper"></property>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>


    <!-- 第三步：事务 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!-- 配置通知 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="save*" propagation="REQUIRED"/>
            <tx:method name="update*" propagation="REQUIRED"/>
            <tx:method name="delete*" propagation="REQUIRED"/>
            <tx:method name="insert*" propagation="REQUIRED"/>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>

    </tx:advice>

    <!-- 配置拦截service -->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.shuyun.service.*.*(..))"/>
    </aop:config>

</beans>

（3）springMVC配置文件

<?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:mvc="http://www.springframework.org/schema/mvc"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.2.xsd
      http://www.springframework.org/schema/aop
      http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
      http://www.springframework.org/schema/tx
      http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">

   <!--扫描的包-->
   <context:component-scan base-package="com.shuyun"></context:component-scan>
  
   <!-- annotation-driven:默认创建了多个对象：RequestMappingHandlerMapping，RequestMappingHandlerAdapter
      也就提供对json格式支持
    -->
   <mvc:annotation-driven/>

   <!-- 配置sprigmvc视图解析器：解析逻辑试图 后台返回逻辑试图：index 视图解析器解析出真正物理视图：前缀+逻辑试图+后缀====/WEB-INF/jsps/index.jsp -->
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/jsps/"></property>
      <property name="suffix" value=".jsp"></property>
   </bean>
</beans>

（4）mybatis配置文件

<?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>
    <!--为po类定义别名-->
    <typeAliases>
        <!--批量定义-->
        <package name="com.shuyun.model"/>

        <!--为指定的某一个类起别名-->
        <!--<typeAlias type="com.shuyun.model.Book"/>-->
    </typeAliases>

    <!-- 加载映射文件 -->
    <mappers>
        <!--加载resource路径下的指定mapper文件-->
         <mapper resource="/mapper/BookMapper.xml" />

        <!-- 批量加载映射文件，idea只能加载resource路径下的配置文件-->
        <!--<package name="com.shuyun.mybatis.mapper" />-->
    </mappers>
</configuration>

         注意：idea不能识别其他路径下的配置文件，所以必须将XXXMapper.xml文件放在resource文件夹下，最好resource文件夹下创建一个mapper文件夹。
