Spring+Mybatis+Struts2框架搭建

总共分为以下几个步骤：

一：导入jar文件包

二在web.xml文件中配置与Struts2相关的filter,在web.xml中将applacation.xml文件位置配置出来。将applacation.xml和struts.xml都放在src文件下面，如图：

web.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5"

    xmlns="http://java.sun.com/xml/ns/javaee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<!-- 加载spring的配置文件 -->

    <listener>

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    </listener>

    <!-- 配置spring配置文件加载的位置 -->

    <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>classpath:applicationContext.xml</param-value>

    </context-param>

<!-- 配置struts2 -->

  <filter>

  <filter-name>struts2</filter-name>

  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

  </filter>

  <filter-mapping>

  <filter-name>struts2</filter-name>

  <url-pattern>/*</url-pattern>

  </filter-mapping>

</web-app>

三：配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"

    "http://struts.apache.org/dtds/struts-2.1.7.dtd">

<struts>

<package name="book"  namespace="/book"  extends="struts-default">

    <action name="searchBook"  class="com.bookstore.action.bookaction.SearchBookAction">

    <result name="success">

        /product.jsp

    </result>

    </action>

    </package>

</struts>

四.：配置application.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: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-3.0.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
           http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    <!-- 配置要扫描的包 -->

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

    <!--proxy-target-class="true"强制使用cglib代理   如果为false则spring会自动选择-->

    <aop:aspectj-autoproxy  proxy-target-class="true"/>

 <!-- 配置数据源 -->

    <bean id="dbcp"

    class="org.apache.commons.dbcp.BasicDataSource">

    <property name="username" value="root">

    </property>

    <property name="password" value="root">

    </property>

    <property name="driverClassName"

        value="com.mysql.jdbc.Driver">

    </property>

    <property name="url"

        value="jdbc:mysql:///bookstore?useUnicode=true&characterEncoding=utf8">

    </property>

</bean>

    <!-- 配置mybitas的SqlSessionFactoryBean -->

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="dbcp" />

        <property name="mapperLocations"   

        value="classpath:com/bookstore/sql/*.xml">        <!-- .xml文件是对应Mapper的xml文件-->

        </property>  

    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

    <!-- 扫描包下接口生成实现 -->

    <property name="basePackage"  value="com.bookstore.dao">

    </property>

</bean>

    <!-- 事务配置 -->

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

        <property name="dataSource" ref="dbcp"/>

    </bean>

    <!-- 使用annotation注解方式配置事务 -->

    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

五：BookMapper.xml文件（写sql语句的xml）配置：

<?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.bookstore.dao.BookDao">

<!-- <typeAlias type="com.bookstore.entity.Book" alias="Book"/> -->

<resultMap type="com.bookstore.entity.Book" id="bookMap">

<id  property="isbn"  column="isbn"/>

</resultMap>

<select id="searchAllBooks" resultMap="bookMap">

    select  *  from book_info

    </select>
