dubbo的权限设置

1、设置token：

http://dubbo.io/User+Guide-zh.htm#UserGuide-zh-%E4%BB%A4%E7%89%8C%E9%AA%8C%E8%AF%81

2、实现dubbo的com.alibaba.dubbo.rpc.Filter接口：

package com.caiya.ucenter.dubbo.filter;

import com.alibaba.dubbo.rpc.*;

/**
 * Created by caiya on 16/3/21.
 */
public class AuthorityFilter implements Filter {

    @Override
    public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {
        String clientIP = RpcContext.getContext().getRemoteHost();
        if(!clientIP.equals("127.0.0.1")){
            return new RpcResult();
        }
        // 通过验证，返回结果
        Result result = invoker.invoke(invocation);
        return result;
    }

}

然后定义resources/META-INF/dubbo/com.alibaba.dubbo.rpc.Filter文件内容：

authorityFilter=com.caiya.ucenter.dubbo.filter.AuthorityFilter

dubbo的配置文件：

<dubbo:service interface="com.caiya.ucenter.service.IUserInfoService" ref="userInfoService" filter="authorityFilter"/>
