dubbo泛化实现方式主要用于服务器端没有API借口及横型类元的情况，参数及返回值中的所有POJO均使用Map表示，通常用于框架集成。比如：实现一个通用的远程服务，可通过实现GenenricService接口实现所有服务请求。
如如下服务实现：

package com.yncp.dubbo.service;import java.util.Date;import com.alibaba.dubbo.rpc.service.GenericException;import com.alibaba.dubbo.rpc.service.GenericService;public class IDubboGenService implements GenericService{    public Object $invoke(String method, String[] parameterTypes, Object[] args)            throws GenericException {         System.out.println("方法:"+method);        System.out.println("parameterTypes:");        for (Object type : parameterTypes) {            System.out.println("\t"+type);        }        System.out.println("args:");        for (Object arg : args) {            System.out.println("\t"+arg);        }        System.out.println("args:"+args);        return new Date();    }}

dubbo.xml配置：

<?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:dubbo="http://code.alibabatech.com/schema/dubbo"    xsi:schemaLocation="http://www.springframework.org/schema/beans            http://www.springframework.org/schema/beans/spring-beans.xsd            http://code.alibabatech.com/schema/dubbo            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <!-- 指定web服务名字 -->    <dubbo:application name="DubboGen"/>    <!-- 声明服务注册中心 -->    <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181"/>    <!-- 指定传输层通信协议 -->    <dubbo:protocol name="dubbo" port="20880"/>    <!-- 暴露你的服务地址 -->    <dubbo:service         ref="dubboGenService"         interface="com.yncp.dubbo.service.IDubboGenService"        protocol="dubbo"    /> </beans>

客户端实现代码如下：

package com.yncp.dubbo.entity;public class User {    private Integer id;    private String name;    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}

package com.yncp.dubbo.service;import com.yncp.dubbo.entity.User;public interface IDubboGenService {    public Object sum(int x,int y);    public Object saveUser(User user);}

import java.io.IOException;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.yncp.dubbo.entity.User;import com.yncp.dubbo.service.IDubboGenService;public class DubboStart {    public static void main(String[] args) throws IOException {       ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");       IDubboGenService dubboGenService=(IDubboGenService) ctx.getBean("dubboGenService");       Object date= dubboGenService.sum(1, 3);       System.out.println(date.toString());       User user=new User();       user.setId(1);       user.setName("张三");       Object obj= dubboGenService.saveUser(user);       System.out.println(obj.toString());    }}

dubbo.xml配置：

<?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:dubbo="http://code.alibabatech.com/schema/dubbo"    xsi:schemaLocation="http://www.springframework.org/schema/beans            http://www.springframework.org/schema/beans/spring-beans.xsd            http://code.alibabatech.com/schema/dubbo            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <!-- 指定web服务名字 -->    <dubbo:application name="DubboGen_ref"/>    <!-- 声明服务注册中心 -->    <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181"/>        <!-- 指定传输层通信协议 -->    <dubbo:protocol name="dubbo" port="20881"/>    <dubbo:protocol name="rmi" port="1010"/>        <!-- 暴露你的服务地址 -->    <dubbo:reference         id="dubboGenService"         interface="com.yncp.dubbo.service.IDubboGenService"        protocol="dubbo"         >    </dubbo:reference> </beans>
