• 三大框架-ssh整合（三）

    struts整合spring:spring创建action

    1.编写action类，并将其配置给spring ，spring可以注入service

    2.编写struts.xml

    3.表单jsp页面

    4.web.xml 配置

           1.确定配置文件contextConfigLocation

           2.配置监听器 ContextLoaderListener

           3.配置前端控制器 StrutsPrepareAndExecuteFitler

    action类如下:

    import com.itheima.UserService.UserService;
import com.itheima.domain.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class UserAction extends ActionSupport implements ModelDriven<User> {

    //1 封装数据
    private User user = new User();
    @Override
    public User getModel() {
        return user;
    }
    
    //2 service
    private UserService userService;
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
    public String register(){
        userService.register(user);
        return "success";
    }

}

    struts.xml如下：

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <!-- 开发模式 -->
    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
        <!-- 底层自动从spring容器中通过名称获得内容， getBean("userAction") -->
        <action name="userAction_*" class="userAction" method="{1}">
            <result name="success">/messag.jsp</result>
        </action>
    </package>
</struts>

    jsp页面：index.jsp(注册页面)  messag.jsp（注册成功页面）

    <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  </head>
  
  <body>
    <form action="${pageContext.request.contextPath}/userAction_register" method="post">
        用户名：<input type="text" name="username"/> <br/>
        密码：<input type="password" name="password"/> <br/>
        年龄：<input type="text" name="age"/> <br/>
        <input type="submit" />
    </form>

  </body>
</html>
    <%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>

<title>Insert title here</title>
</head>
<body>
  注册成功
</body>
</html>

    web.xml配置：

    <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.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.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

    其他的User类，UserDao类，UserService类，以及对应的数据库的表t_user与之前的整合（二）均是一模一样
    applicationContext.xml文件中在前面整合hibernate的基础上只增加如下代码：即整合struts

    <!-- 6 配置action -->
    <bean id="userAction" class="com.itheima.action.UserAction" scope="prototype">
        <property name="userService" ref="userService"></property>
    </bean>

    则最后的applicationContext.xml文件如下：

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        3) 导入映射文件
            mappingLocations ，确定映射文件位置，需要“classpath:” ,支持通配符 【】
                <property name="mappingLocations" value="classpath:com/itheima/domain/User.hbm.xml"></property>
                <property name="mappingLocations" value="classpath:com/itheima/domain/*.hbm.xml"></property>
            mappingResources ，加载执行映射文件，从src下开始 。不支持通配符*
                <property name="mappingResources" value="com/itheima/domain/User.hbm.xml"></property>
            mappingDirectoryLocations ，加载指定目录下的，所有配置文件
                <property name="mappingDirectoryLocations" value="classpath:com/itheima/domain/"></property>
            mappingJarLocations ， 从jar包中获得映射文件
