dwr3.0可以通过全注解的方式，极大的简化了配置，所有xml配置加在一起不超过20行，而且使用更加简单，bean注入的问题也都解决。配置步骤如下：

web.xml的配置文件中，在默认的DispatcherServlet的mapping里加上dwr

<servlet>        <servlet-name>appServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/spring/appServlet/appServlet-context.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>appServlet</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>appServlet</servlet-name>        <url-pattern>/dwr/*</url-pattern>    </servlet-mapping>

dispatcherServlet的配置文件appServlet-context.xml

<?xml version="1.0" encoding="UTF-8"?><beans:beans xmlns="http://www.springframework.org/schema/mvc"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd        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">    <!-- DispatcherServlet Context: defines this servlet's request-processing         infrastructure -->    <!-- Enables the Spring MVC @Controller programming model -->    <annotation-driven />    <!-- Handles HTTP GET requests for /resources/** by efficiently serving         up static resources in the ${webappRoot}/resources directory -->    <resources mapping="/resources/**" location="/resources/" />    <interceptors>        <beans:bean class="com.panguso.op.data.manager.interceptor.LogInterceptor"></beans:bean>    </interceptors>    <!-- Resolves views selected for rendering by @Controllers to .jsp resources         in the /WEB-INF/views directory -->    <beans:bean        class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <beans:property name="prefix" value="/WEB-INF/views/" />        <beans:property name="suffix" value=".jsp" />    </beans:bean>    <!--<view-controller path="/" view-name="index" /> -->    <context:component-scan base-package="com.panguso.op.data.manager" />    <!-- 从这行往下是要添加的 -->    <context:annotation-config />    <dwr:configuration />    <dwr:annotation-config />    <dwr:url-mapping />    <dwr:controller id="dwrController" debug="true">        <dwr:config-param name="allowScriptTagRemoting"            value="true" />        <dwr:config-param name="crossDomainSessionSecurity"            value="false" />    </dwr:controller>    <beans:bean        class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">        <beans:property name="order" value="1" />    </beans:bean>    <beans:bean        class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">        <beans:property name="order" value="2" />    </beans:bean>    <!--添加结束--></beans:beans>

配置完毕，使用的方法和上文类似，注意的是@RemoteProxy标注的远程类一定要加上name属性，不然启动会报错，如：

@Service@RemoteProxy(name = "GeneralContentManagementService")public class GeneralContentManagementService {    @RemoteMethod    public void aaa()    {    }}
