DWR+SpringMVC整合的3种方式之二

方式二：使用springmvc的控制器代替dwr的，加上相应的mapping，省掉了dwr.xml文件

说明：dwr与spring耦合度提高，做这个例子的时候，我原来是用的spring4.0以上的版本，结果很遗憾，一直搞定不了，原因就是dwr好像还不支持spring高的版本。

主要错误如下：

java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.forName(Ljava/lang/String;)Ljava/lang/Class;

所以没办法，换了spring低的版本，运行jetty，一切ok

</project>


2、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">

    <!-- 创建Spring的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- Spring 的监听器可以通过这个上下文参数来获取beans.xml的位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:beans.xml</param-value>
    </context-param>
	
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
         <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <filter>
        <filter-name>characterFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>
     
</web-app>

3、java类 

package com.lessony.dwr.spring02.entity;

public class User {
	private int id;
	private String name;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public User() {
	}
	public User(int id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
}



package com.lessony.dwr.spring02.service;

import com.lessony.dwr.spring02.entity.User;

public interface IHelloService {
	public String sayHello(String name);
        
        public User load();
}


package com.lessony.dwr.spring02.service.impl;

import com.lessony.dwr.spring02.entity.User;
import com.lessony.dwr.spring02.service.IHelloService;

public class HelloService implements IHelloService {

    @Override
    public String sayHello(String name) {
        System.out.println("hello " + name);
        return "hello: "+name;
    }

    @Override
    public User load() {
        System.out.println("load abc");
        return new User(1,"abc");
    }

}

4、配置dwr，在dispatcher-servlet.xml中配置 

<?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:dwr="http://www.directwebremoting.org/schema/spring-dwr"
	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-3.2.xsd
            http://www.springframework.org/schema/mvc 
            http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
            http://www.directwebremoting.org/schema/spring-dwr
            http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">
	
	<mvc:annotation-driven/>
	<mvc:resources location="/resources/" mapping="/resources/**"/>
   
        <!--dwr过滤-->
        <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
	  <property value="true" name="alwaysUseFullPath"></property> 
	  <property name="mappings">
	    <props> 
	      <prop key="/dwr/**/*">dwrController</prop>
	    </props>
	 </property> 
	</bean>
	
        <!--dwr控制器-->
	<dwr:controller id="dwrController" debug="true"/>
        
        <!--设置需要dwr转化的实体类，格式为json传输到jsp页面-->
	<dwr:configuration>
		<dwr:convert type="bean" class="com.lessony.dwr.spring02.entity.User"/>
	</dwr:configuration>
	
	<bean id="helloService" class="com.lessony.dwr.spring02.service.impl.HelloService">
		<dwr:remote javascript="hello02">
		    <dwr:include method="load" />
		</dwr:remote>
	</bean>
	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/"/>
		<property name="suffix" value=".jsp"/>
	</bean>
</beans>


<?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:p="http://www.springframework.org/schema/p"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
 
	<!-- 打开Spring的Annotation支持 -->
	<context:annotation-config />
	<!-- 设定Spring 去哪些包中找Annotation -->
	<context:component-scan base-package="com.lessony.dwr.spring02" />

</beans>

5、jsp文件 

<%-- 
    Document   : dwr01
    Created on : 2015-5-14, 2015-5-14 20:45:21
    Author     : Lessony
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
        <script src="<%=request.getContextPath()%>/dwr/engine.js"></script>
        <script src="<%=request.getContextPath()%>/dwr/interface/hello02.js"></script>
        
        <script>            
            hello02.load(function(data){
                alert("mmmmmmm");
		alert(data.name);
            });
        </script>
    </head>
    <body>
        <h1>Hello World!</h1>
    </body>
</html>

全部编辑完成之后，，右键项目，选择Run As... 继续选择7 Maven build...  ，在弹出框的Goals中输入jetty:run ，然后点击RUN运行。

打开浏览器，输入http://localhost:8806/dwr-spring02/dwr02.jsp，就可以看到控制台输出了：load abc，jsp页面弹出了mmmmmm和弹出了用户名：abc

最后附上zip包，链接：http://download.csdn.net/detail/lxn39830435731415926/8714153
