dubbo学习笔记

一.前置环境

使用dubbo首先需要在Linux上安装zookeeper。同时最好安装dubbo-admin方便管理与调试，下载dubbo-admin的war包放入tomcat即可

二.使用

按照官网上的用户手册即可，需要注意以下几点

1.dubbo依托于Spring，需要通过Spring启动

2.dubbo内部集成了Spring2.x的包，使用maven时需要忽略这些包。pom文件如下

<?xml version="1.0" encoding="UTF-8"?>

3.dubbo仅记录本地IP。无法记录NAT前的IP

4.不支持AutoWire注解

5.需要本地和服务方接口全限定名相同，方法签名相同。
