java 的 struts2 Spring Hibernate 三大框架的整合

原理就不說了，直接上配置文件及代碼，用來備用

首先，將三大框架所須要的jar包導入項目中

導入  struts2-spring-plugin-2.3.3.jar包  此包的做用是做爲struts2 與spring 的橋樑

web.xml

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

建立在src 中建立hibernate 配置文件applicationContext.xml

applicationContext.xml

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

    xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- 數據源 dataSource -->
    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName"
            value="com.mysql.jdbc.Driver">

        <property name="password" value="root"></property>
    </bean>
    
    <!-- sessionFactory -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQLDialect
                </prop>
            </props>
        </property>
    </bean>
    
    <!-- 事務管理器     -->

        <property name="sessionFactory">

        </property>
    </bean>
    
    <!-- 事務的聲明        
        read-only
                   true   只讀事務
                   false  讀寫事務
     -->
    
    <tx:advice  transaction-manager="transactionManager" id="tx">
        <tx:attributes>    
            <!-- 事務應用方法範圍 -->
            <tx:method name="save*" isolation="DEFAULT" propagation="REQUIRED"
              read-only="false"/>

        <aop:advisor advice-ref="tx" pointcut-ref="perform"/>
    </aop:config>
    
    
</beans>

在sr下面建立  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>

驗證：驗證struts2 與spring 是否整合

建立實體類person

package com.cong.domain;



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

建立Action 類

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中添加配置以下

<!-- 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中添加配置以下：

<?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>    

接下來，直接運行項目，在瀏覽器中輸入地址  http://[地址]:8080/[項目名]/perAction.action

若有運行showPerson 方法，輸出名字，則表示spring 與 struts 整合完成
