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

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@H_502_7@
@RemoteProxy@H_502_7@(name = "GeneralContentManagementService"@H_502_7@)
public@H_502_7@ class@H_502_7@ GeneralContentManagementService@H_502_7@ {@H_502_7@

    @RemoteMethod@H_502_7@
    public@H_502_7@ void@H_502_7@ aaa@H_502_7@()
    {
    }
}
