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

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:mvc="http://www.springframework.org/schema/mvc"
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"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd 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，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
