搭建：spring boot +dubbo +zookeeper+ngnix

1.zookeeper安装

官网：http://zookeeper.apache.org/，

修改配置文件：zoo.cfg   lg4j.properties

启动zookeeper:

2.Springboot搭建dubbo项目

服务提供端

Service 接口：

public interface UserService {

    public String getUserInfo(String name);
}

Service 接口实现：

@Service //必须是dubbo下的Sservice
public class UserServiceImpl implements UserService {
    @Override
    public String getUserInfo(String name) {
        return "我是服务提供者：your name is " + name;
    }
}

application.properties文件配置

server.port=8004
spring.dubbo.application.name=dubbo-user
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.huayu.user.dubbo

消费者：

Service接口：

package com.huayu.user.dubbo;


public interface UserService {

    public String getUserInfo(String name);
}

package com.huayu.user.dubbo;

import com.alibaba.dubbo.config.annotation.Reference;
import org.springframework.stereotype.Component;


@Component
public class SubUserService {

    @Reference
    private UserService mUserService;

    public String getUser(String name) {
        return mUserService.getUserInfo(name);
    }
}

application.properties文件配置

server.port=8004

## Dubbo 服务消费者配置
spring.dubbo.application.name=dubbo-sub
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.scan=com.huayu.user.dubbo

消费者调用：

package com.huayu.subscription.controller;

import com.huayu.user.dubbo.SubUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class SubHelloController {

    @Autowired
    private SubUserService mSubUserService;

    @GetMapping(value = "hello")
    public String hello(String name) {
        return "远程调用：" + mSubUserService.getUser(name);
    }

    @GetMapping(value = "hello1")
    public String haha() {
        return "我是消费者";
    }
}

打包war文件部署到tomcat

3.安装：dubbo管理平台 

官网地址：https://github.com/apache/incubator-dubbo

重新打包 dubbo-admin 项目 为war文件 放入 ：F:\apache-tomcat-8.5.31\webapps  启动tomcat  修改自己的端口号 现实如下网站  说明部署正确

 

 

4.ngnix安装：

下载地址：http://nginx.org/en/download.html 选择自己需要的版本

配置文件：F:\nginx-1.15.8\conf\nginx.conf

 

listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location /UserServer/ {
            proxy_pass   http://127.0.0.1:8004/UserServer/;
		}
		location /SubServer/ {
            proxy_pass   http://127.0.0.1:8004/SubServer/;
		}

最终实现：http://localhost/SubServer/hello?name=zhangsan   ----> 远程调用：我是服务提供者：your name is  zhangsan
