DWR3基于Spring MVC配置Controller的方法

DWR3 可以使用Spring MVC来进行url映射，配置如下：

web.xml

    <servlet>
      <servlet-name>dwr</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
    </servlet>   
    <servlet-mapping>
      <servlet-name>dwr</servlet-name>
      <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>  
    <servlet>

需要一个dwr-servlet.xml的文件：

<?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:dwr="http://www.directwebremoting.org/schema/spring-dwr"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd      
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">


    <!-- 将util.js和engine.js映射到下面的dwrController -->
    <dwr:url-mapping />

    <!-- debug开启 -->
    <dwr:controller id="dwrController" debug="true" >
        <!-- 如果有反向Ajax调用 -->
        <dwr:config-param name="activeReverseAjaxEnabled" value="true" />
    </dwr:controller>

</beans>

然后在Spring 的主配置加入如下配置，就可以使用DWR标注了

    <!-- 启用 annotation 配置模式 -->
    <dwr:configuration >
       <dwr:convert type="bean" class="org.feifei.*"></dwr:convert>
    </dwr:configuration>

    <!-- Spring容器中检查拥有@RemoteProxy 和 @RemoteMethod注解的类 -->
    <dwr:annotation-config>
    </dwr:annotation-config>
