嗨,我使用的是Spring引导和Spring数据,我希望根据id从数据库中获取数据,但是我无法检索它.M得到此错误"异常":

"org.springframework.dao.InvalidDataAccessApiUsageException", "消息":"org.hibernate.hql.internal.QueryExecutionRequestException:不支持DML操作[更新com.ge.health.poc.model.SpringModel SET NAME = '斯纳',其中？ID =];嵌套的例外是java.lang.IllegalStateException:org.hibernate.hql.internal.QueryExecutionRequestException:不支持DML操作[更新com.ge.health.poc.model.SpringModel SET NAME = '斯纳' 其中id =？]","path":"/ updatedata"}

主类

  package com.ge.health.poc;

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

  @SpringBootApplication
  public class SpringDataApplication {

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

控制器类

    package com.ge.health.poc.controller;

我是 JUnit 测试的新手。你能告诉我如何对 void 方法进行 Junit 测试吗？

我有这个类DemoPublisher和这个demoPublishMessage()返回类型为void的方法。我如何测试这种方法？

package com.ge.health.gam.poc.publisher;

import javax.jms.JMSException;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.ResponseBody;

import com.ge.health.gam.poc.consumer.DemoConsumer;

@Component
public class DemoPublisher {

    @Autowired
    JmsTemplate jmsTemplate;

    public void demoPublishMessage(String message) throws JMSException{
        jmsTemplate.convertAndSend("NewQueue", message);
        System.out.println("Message sent");

    }
}
