SpringBoot(2.1.6) + dubbo(apache 2.7.5) + zookeeper 集成并测试

Demo地址：https://github.com/bestksl/DubboDemo02
由于嫌麻烦 依赖基本都放到模块外部的project pom里了， 大家可以选择导入相应的子模块。

api模块定义接口

package com.bestksl.service;

/**
 * @author HaoxuanLi
 * @version 1.0
 * @date 2020/3/17 17:32
 */
public interface UserServiceApi {
    String sayHello(String name);
}

provider实现接口

package com.bestksl.service;


import org.apache.dubbo.config.annotation.Service;

/**
 * @author HaoxuanLi
 * @version 1.0
 * @date 2020/3/17 17:36
 */
@Service(version = "1.0")
public class UserService implements UserServiceApi {
    @Override
    public String sayHello(String name) {
        return "hello" + name + System.currentTimeMillis() / 1000;
    }
}

consumer调用接口

package com.bestksl;

import com.bestksl.service.UserServiceApi;
import org.apache.dubbo.config.annotation.Reference;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author HaoxuanLi
 * @version 1.0
 * @date 2020/3/17 18:52
 */

@RestController
public class userInfoController {

    @Reference(version = "1.0")
    UserServiceApi userServiceApi;

    @GetMapping("/testUserApi")
    public String testUser() {
        return userServiceApi.sayHello("ksl666");
    }
}

成功！
