IDEA整合Spring+Struts+Hibernate项目

新手使用idea整合Spring+Struts+Hibernate项目

项目所需jar下载：

https://download.csdn.net/download/weixin_44906002/12505287

1、如图，使用idea新建一个struts的web项目，点击next，编辑项目名称，点击finish

2、在web/WEB-INF下创建lib文件夹，导入下载好的jar包，然后鼠标右键点击lib，选择添加为库

3、构建如下图的项目结构： 

 4、编辑beans.xml,该配置文件可以创建项目的时候选择spring项目，自动创建，路径随意，一般自动创建的applicationContext.xml在web/WEB-INF文件夹下面。

对beans.xml做如下配置

<?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:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="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-4.1.xsd
       http://www.springframework.org/schema/cache
       http://www.springframework.org/schema/cache/spring-cache.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--开启包扫描-->
    <context:component-scan base-package="com.cheng.*"/>
    <!--配置数据源，这里使用的是c3p0连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.cj.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/shape?userUnicode=true&amp;characterEncoding=utf-8"/>
        <property name="user" value="root"/>
        <property name="password" value="lijc19980218"/>
    </bean>
    <!--配置Hibernate的会话工厂bean-->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"/>
        <!--Hibernate配置文件位置-->
        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
    </bean>
    
    <!--配置事务管理器，将事务管理交给spring-->
    <bean id="txManger" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <!--定义事务通知-->
    <tx:advice id="txAdvice" transaction-manager="txManger">
        <tx:attributes>
            <!--事务方法-->
            <tx:method name="save*" propagation="REQUIRED"/>
            <tx:method name="add*" propagation="REQUIRED"/>
            <!--...-->
        </tx:attributes>
    </tx:advice>
    
    <!--配置AOP-->
    <aop:config>
        <aop:pointcut id="service" expression="execution(* com.cheng.service..*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="service"/>
    </aop:config>

</beans>

5、配置hibernate.cfg.xml文件

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!--映射文件-->
        <mapping resource="com/cheng/bean/circle.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

6、配置struts.xml，让spring融合struts

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

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
    <!--配置struts为开发模式-->
    <constant name="struts.devMode" value="true"/>
    <!--配置主题为简单主题-->
    <constant name="struts.ui.theme" value="simple"/>
    <!--配置请求后缀-->
    <constant name="struts.action.extension" value="do"/>
    <!--使用Spring的对象工厂-->
    <constant name="struts.objectFactory" value="spring"/>
    <package name="default" extends="struts-default" namespace="/">
        
    </package>
</struts>

7、配置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_4_0.xsd"
         version="4.0">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:beans.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

<context-param></context-param>存放的是beans.xm配置文件路径，添加监听以便于在部署Web项目时，启动和初始化Spring容器。

8、hibernate映射文件，例如：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="完全限定类名" table="映射数据库表名">
        <id name="主键">
            <generator class="assigned"></generator>
        </id>

        <property name="其他字段"></property>

    </class>

</hibernate-mapping>

 

然后爽一波试试好不好使
