[Java知识库]dubbo可视化界面工具安装（zookeeper、linux、provider、consumer）实例配置、测试、运行

dubbo可视化界面工具安装（zookeeper、linux、provider、consumer）实例配置、测试、运行

一、安装linux和zookeeper并配置

一文就够了（安装linux和zookeeper并配置）

二、构建服务提供者(Provider)项目

构建一个web的maven项目

过程不再演示
在这里插入图片描述

创建业务层（简单做个测试）

在这里插入图片描述

代码如下：

HelloService接口

package cn.ebuy.service;

public interface HelloService {

    public String sayHello(String name);
}

HelloServiceImpl实现类

package cn.ebuy.service.impl;

import cn.ebuy.service.HelloService;
import com.alibaba.dubbo.config.annotation.Service;

@Service
public class HelloServiceImpl implements HelloService {
    @Override
    public String sayHello(String name) {
        return "hello"+name;
    }
}

</web-app>

至此provider服务提供者便构建完成！！！
然后启动试试

接下来试试我们的dubbo-admin可视化界面吧

三、dubbo-admin工具使用

注：因为该版本似乎只能使用jdk8，所以我们要下载jdk8，并配置环境变量

小疑惑：
关于为什么管JDK1.8为JDK8的解读文章

安装配置JDK8

官网下载JDK8或者国内镜像下载
- 官网地址
然后安装，选好路径
然后进行环境变量配置

JAVA_HOME
jdk安装路径
path

%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%JAVA_HOME%\bin;

然后测试jdk版本

下载dubbo-admin

dubbo-admin我是用的2.6版本，可以自己百度下载
发布dubbo-admin

启动tomcat

启动tomcat会自动将我们的war包解压到同级目录下

在这里插入图片描述

如果启动闪退，可以右键startup.bat，使用记事本编辑，新起一行为（具体可以再百度）

修改被解压后的dubbo-admin的配置文件

在这里插入图片描述

修改为
如果不知道ip地址为多少的话，可以在linux终端输入ifconfig查看

重启tomcat

双击startup.bat重启

测试dubbo-admin

在这里插入图片描述

首次登陆需要账户，密码（都是root）

可以看到注册好的业务

至此dubbo-admin便配置完成了

四、构建服务消费者(Consumer)项目

构建一个web的maven项目

在这里插入图片描述

引入jar包

    private HelloService helloService;

    @RequestMapping("/hello")
    @ResponseBody
    public String getName(String name){
        //远程调用
