DWR+SpringMVC整合的3種方式之二
方式二：使用springmvc的控制器代替dwr的，加上相應(yīng)的mapping，省掉了dwr.xml文件
說(shuō)明：dwr與spring耦合度提高，做這個(gè)例子的時(shí)候，我原來(lái)是用的spring4.0以上的版本，結(jié)果很遺憾，一直搞定不了，原因就是dwr好像還不支持spring高的版本。
主要錯(cuò)誤如下：
java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.forName(Ljava/lang/String;)Ljava/lang/Class;
所以沒(méi)辦法，換了spring低的版本，運(yùn)行jetty，一切ok

3、java類(lèi)
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

</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>
全部編輯完成之后，，右鍵項(xiàng)目，選擇Run As... 繼續(xù)選擇7 Maven build... ，在彈出框的Goals中輸入jetty:run ，然后點(diǎn)擊RUN運(yùn)行。
打開(kāi)瀏覽器，輸入http://localhost:8806/dwr-spring02/dwr02.jsp，就可以看到控制臺(tái)輸出了：load abc，jsp頁(yè)面彈出了mmmmmm和彈出了用戶名：abc
最后附上zip包，鏈接：http://download.csdn.net/detail/lxn39830435731415926/8714153
