java 的 struts2 Spring Hibernate 三大框架的整合

Posted 2020-08-23 千年问心

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">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <!-- 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>
  
  <!-- 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"

    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-3.1.xsd
     http://www.springframework.org/schema/tx 
     http://www.springframework.org/schema/tx/spring-tx.xsd
     http://www.springframework.org/schema/aop
     http://www.springframework.org/schema/aop/spring-aop-3.1.xsd"     >

    <!-- 数据源 dataSource -->
    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName"
            value="com.mysql.jdbc.Driver">
        </property>
        <property name="url" value="jdbc:mysql://localhost:3306/test"></property>
        <property name="username" value="root"></property>
        <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        
        read-only
                   true   只读事务
                   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
