本文介绍DWR3与Spring3的三种整合方式，包括使用spring-dwr名字空间、注解及DWRSpringServlet。特别详细说明了通过注解实现整合的具体步骤。

dwr3整合spring3有3种方式

web.xml中的必要配置

如果希望是用springmvc,则在web.xml中

<servlet>
  <servlet-name>springDispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value> classpath:yourSpringContext.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>springDispatcher</servlet-name>
  <url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
  <servlet-name>springDispatcher</servlet-name>
  <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

如果不需要springmvc 则使用DWRSpringServlet

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    classpath:yourSpringContext.xml
  </param-value>
</context-param>
<servlet>
  <servlet-name>dwr</servlet-name>
  <servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>
  <init-param>
    <param-name>debug</param-name>
    <param-value>true</param-value>
  </init-param>
</servlet>
<servlet-mapping>
  <servlet-name>dwr</servlet-name>
  <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

配置3种方式

第一，使用spring-dwr的名字空间

第二，采用注解

第三，使用DWRSpringServlet (必须要有dwr.xml)

只说下采用注解的实现吧

配置如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">
	<dwr:configuration>
		<dwr:convert type="bean" class="com.pjj.*"></dwr:convert> 
	</dwr:configuration>
	<dwr:annotation-scan base-package="com.xxx.xxx" scanDataTransferObject="true" scanRemoteProxy="true"/>
	</beans>

java代码

@RemoteProxy(name="loginDwr")
public class LoginDwr {

	@RemoteMethod
	public String login(Users user){
		
		
	    return null;	
	}
}
