启动类

package com.example.dubboapitestdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DubboapitestdemoApplication {


    public static void main(String[] args) {
        SpringApplication.run(DubboapitestdemoApplication.class, args);
    }

}

resources下添加了dubbo.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

    <dubbo:application name="dubboapitestdemo" />
    <dubbo:registry  protocol="zookeeper"  address="127.0.0.1:2181" check="false" timeout="10000"/>
    <dubbo:protocol name="dubbo" port="20880" />
    <dubbo:reference id="helloService" interface="com.example.commonapi.service.HelloService" />
    <dubbo:reference id="studentService" interface="com.example.commonapi.service.StudentService" />

</beans>

使用背景：
对dubbo接口，想用testng实现接口自动化测试，新建的springboot，启动是正常的，后面引入了testng、dubbo的相关依赖后，再执行启动程序就报上面错了。测试类@test注解的方法是可以成功执行的。对java的话，熟悉基础部分，对框架不懂原理，是查了很多帖子依葫芦画瓢。希望描述清楚了，继续补充

测试类demo：

package com.example.dubboapitestdemo.testcase;

import com.example.commonapi.entity.Student;
import com.example.commonapi.service.StudentService;
import com.example.commonapi.utils.ResultVO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.testng.Assert;
import org.testng.annotations.Test;

import java.util.Date;

public class StudentServiceTest {

    @Autowired
    StudentService studentService;

    @Test
    public void insertStudentSuccessTest() {
        ClassPathXmlApplicationContext context =
                new ClassPathXmlApplicationContext(new String[]{"dubbo.xml"});
        context.start();
        studentService = (StudentService) context.getBean("studentService");
        Student student = new Student();
        student.setSname("yoyo");
        student.setSsex("female");
        student.setSbirthday(new Date(20101013));
        student.setClazz("20150");
        ResultVO resultVO = studentService.insertStudent(student);
        System.out.println("~~~~~~~~~~~~~~~~~~~返回数据~~~~~~~~~~~~~~~~~~~~~~~~");
        System.out.println(resultVO);
        System.out.println(resultVO.getCode() + "" + resultVO.getMsg() + resultVO.getData());
        Assert.assertEquals(resultVO.getCode(), 1000);
    }

}
