java 的 struts2 Spring Hibernate 三大框架的整合

原理就不说了,直接上配置文件及代码,用来备用

首先,将三大框架所需要的jar包导入项目中

导入  struts2-spring-plugin-2.3.3.jar包  此包的作用是作为struts2 与spring 的桥梁

web.xml

<?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">

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- 配置struts2 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>

</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> <!-- 设置监听器及路径 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 启动时,配置文件的路径
classpath:编译后配置文件所放置的位置
-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> </web-app>

创建在src 中创建hibernate 配置文件applicationContext.xml

applicationContext.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"

<property name="password" value="root"></property>
</bean> <!-- sessionFactory -->

</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
</props>
</property>
</bean> <!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean> <!-- 事务的声明

false 读写事务
--> <tx:advice transaction-manager="transactionManager" id="tx">
<tx:attributes>
<!-- 事务应用方法范围 -->
<tx:method name="save*" isolation="DEFAULT" propagation="REQUIRED"
read-only="false"/>
</tx:attributes>
</tx:advice> <!-- 事务切面 -->
<aop:config>
<aop:pointcut
expression="execution(* *.*.*(..))"
id="perform"/>
<aop:advisor advice-ref="tx" pointcut-ref="perform"/>
</aop:config> </beans>

在sr下面创建  struts.xml配置文件

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd"> <struts>
<constant name="struts.ui.theme" value="simple"></constant>
<constant name="struts.devMode" value="true"/>
<include file="struts/struts-person.xml"></include>
<!-- 配置的例子 -->
<package name="struts-global" namespace="/" extends="struts-default">
<global-results>
<result name="errHandler" type="chain">
<param name="actionName">errorProcessor</param>
</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="java.lang.Exception"
result="errHandler" />
</global-exception-mappings> <action name="errorProcessor" class="com.itheima12.s2sh.error.ErrorProcessor">
<result name="error">error.jsp</result>
</action>
</package>
</struts>

验证:验证struts2 与spring 是否整合

创建实体类person

package com.cong.domain;

public class person {
private Long id;
private String name;
public Long getId() {
return id;
} //set and get ... }

创建Action 类

package com.cong.action;
import com.cong.domain.person;
import com.opensymphony.xwork2.ActionSupport; public class personAction extends ActionSupport {
private person persons; public void showPerson(){
System.out.println("名字是:"+persons.getName());
}
// set and get ...
}

在applicationContext.xml中添加配置如下

<!-- domain -->
<bean id="Person" class="com.cong.domain.person" />
<!-- action -->
<bean id="PersonAction" class="com.cong.action.personAction">
<property name="persons" ref="Person"></property>
</bean>

在struts.xml中添加配置如下:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<constant name="struts.ui.theme" value="simple"></constant>
<constant name="struts.devMode" value="true"/>
<include file="struts/struts-person.xml"></include>
<!-- 配置的例子 -->
<package name="struts-global" namespace="/" extends="struts-default">
<action name="perAction" class="PersonAction" method="showPerson">
<result></result>
</action>
</package>
</struts>

接下来,直接运行项目,在浏览器中输入地址  http://[地址]:8080/[项目名]/perAction.action

如有运行showPerson 方法,输出名字,则表示spring 与 struts 整合完成
