 重点关注 Caused by: javax.persistence.TransactionRequiredException: Executing an update/delete query。简单来说就是我们在执行更行操作时没有添加事务管理。

 注意：springDataJpa中使用jpql完成 更新/删除操作 时 需要手动添加事务的支持

 

 解决方案：

一、在dao层接口方法上直接添加事务管理(不推荐)

package com.heima.dao;

import com.heima.domain.Customer;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.transaction.annotation.Transactional;

public interface CustomerDao extends JpaRepository,JpaSpecificationExecutor {

    @Modifying
    @Transactional
    @Query(value = " update Customer set custName = ?2 where custId = ?1 ")
    void updateCustomer(long custId,String custName);
}

 二、在测试类方法上添加事务管理，并且回滚事务（不自动回滚事务）（不推荐）

package cn.itcast.test;

import cn.itcast.dao.CustomerDao;
import cn.itcast.domain.Customer;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.jpa.repository.Query;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import java.util.Arrays;
import java.util.List;

@RunWith(SpringJUnit4ClassRunner.class) //声明spring提供的单元测试环境
@ContextConfiguration(locations = "classpath:applicationContext.xml")//指定spring容器的配置信息
public class JpqlTest {
    @Autowired
    private CustomerDao customerDao;


    /**
     * 测试jpql的更新操作
     *  * springDataJpa中使用jpql完成 更新/删除操作
     *         * 需要手动添加事务的支持
     *         * 默认会执行结束之后，回滚事务
     *   @Rollback : 设置是否自动回滚
     *          false | true
     */
    @Test
    @Transactional //添加事务的支持
    @Rollback(value = false)
    public void testUpdateCustomer() {
        customerDao.updateCustomer(4l,"黑马程序员");
    }
}

 三、添加service层，在在service层添加事务控制管理（推荐）

=======Service层====================================
    @Autowired
    private CustomerDao customerDao;

    @Transactional
    public void updateCustomer(long custId,String custName){
        customerDao.updateCustomer( custId, custName);
    }

======Dao层==============================================
    @Modifying
    @Query(value = " update Customer set custName = ?2 where custId = ?1 ")
    void updateCustomer(long custId,String custName);

======测试类============================================

    @Autowired
    private CustomerDao customerDao;

    @Test
    public void updateCustomer(){
        customerService.updateCustomer( 3l ,"小星星");
    }
