SpringBoot手动管理事务

springboot 开启事务以及手动提交事务

需要在服务类上加上两个注解

@Autowired
DataSourceTransactionManager dataSourceTransactionManager;
@Autowired
TransactionDefinition transactionDefinition;

手动开启事务
TransactionStatus transactionStatus = dataSourceTransactionManager.getTransaction(transactionDefinition);
手动提交事务
dataSourceTransactionManager.commit(transactionStatus);//提交
手动回滚事务
dataSourceTransactionManager.rollback(transactionStatus);//最好是放在catch 里面,防止程序异常而事务一直卡在哪里未提交
 

package com.java.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.TransactionDefinition;
import org.springframework.transaction.TransactionException;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.RequestMapping;

import com.java.entity.User;
import com.java.service.impl.UserServiceImpl;
@Controller
@RequestMapping(value = "/p")
public class tt {
	@Autowired
	public UserServiceImpl t;
	@Autowired
	DataSourceTransactionManager dataSourceTransactionManager;
	@Autowired
	TransactionDefinition transactionDefinition;
	@RequestMapping(value = "/test")
	public   void  jj(){
		TransactionStatus transactionStatus=null;
		try {

			User user=new User();
			user.setId("12");
			user.setUsername("nihao");

		} catch (Exception e) {
			if(transactionStatus!=null){
				dataSourceTransactionManager.rollback(transactionStatus);
			}
			
			e.printStackTrace();
		}
	}
