DWR3.0和Spring2.5的完美整合的應用開發

 

  在項目中開始使用DWR1.0發現DWR2.0有注解后，采用DWR2.0注解，但是遮增加了web.xml 中DWRServlet中classes參數的信息。終于DWR3.0發布了。采用DWR3.0開發實現完美整合。

DWR 3.0 RC1发布

DWR终于到达3.0版本，刚刚发布了3.0 release candidate 1。DWR(Direct Web Remoting)是一个WEB远程调用框架，能够在javascript直接调用java方法，而不必去写一大堆的javascript代码，利用这个框架可以让AJAX开发变得很简单.

新功能包括：提升RPC性能；提升字节文件上传/下载功能；通过JavaScript实现Java接口；提供可扩展的反向Ajax APIs；TIBCO GI集成；集成Dojo；支持更多的服务器比如Tomcat和Glassfish等等。

package com.unutrip.spring.dwr;

/**

public interface UserService {
 public String getUsername(UserVO user);

}

 

package com.unutrip.spring.dwr;

/**

@RemoteProxy(creator = SpringCreator.class, creatorParams = @Param(name = "beanName", value = "userServiceDWR"))
public class UserServiceDWR {
 @Autowired
 private UserService userService;

 @RemoteMethod
 public String getUsername(UserVO user) {
  return this.userService.getUsername(user);
 }

 public UserService getUserService() {
  return userService;
 }

 public void setUserService(UserService userService) {
  this.userService = userService;
 }
}

 

package com.unutrip.spring.dwr;

import org.springframework.stereotype.Service;

/**
 *
 * @author longgangbai
 *
 */
@Service
public class UserServiceImpl implements UserService {

 public String getUsername(UserVO user) {
  return user.getUsername();
 }

}

 

package com.unutrip.spring.dwr;

import org.directwebremoting.annotations.DataTransferObject;
import org.directwebremoting.annotations.RemoteProperty;

/**
 *
 * @author longgangbai

@DataTransferObject
public class UserVO {
 @RemoteProperty

 @RemoteProperty

 public String getUsername() {
  return username;

 public void setUsername(String username) {
  this.username = username;
 }

 public String getPassword() {
  return password;
 }

 public void setPassword(String password) {
  this.password = password;
 }

}

在applicationContext中配置如下：

 

<?xml version="1.0" encoding="UTF-8"?>

在action－servlet.xml配置如下：

用的2.5.6
google了一下，好像是dwr的bug

天一 写道

兄弟，有没有遇到过这个错误：
No adapter for handler [org.directwebremoting.spring.DwrController@1fd3297]: Does your handler implement a supported interface like Controller?

此处的DWR使用注解的时，必须和spring的整合的Spring2.5版本的
Controller为Spring2.5的控制器哦！
