@RemoteProxy()注释
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

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()
{
}
}
