编程式事务之手动提交

package com.csw.shuanfa.CodeImprove.Transaction;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.DefaultTransactionDefinition;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 */
@RestController
@RequestMapping("Transation")
public class PersonTransation {

    @Autowired
    private PlatformTransactionManager platformTransactionManager;

    @RequestMapping("show")
    public void show() {
        TransactionStatus transactionStatus = platformTransactionManager.getTransaction(new DefaultTransactionDefinition());

        try {
            System.out.println(">>>>>>数据库操作");
        } catch (Exception e) {//放开异常范围
            platformTransactionManager.rollback(transactionStatus);
            throw e;
        }
        //全部成功在提交
        platformTransactionManager.commit(transactionStatus);
    }
}

编程式事务自动提交

package com.csw.shuanfa.CodeImprove.Transaction;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.support.TransactionTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 【编程式事务】
 */
@RestController
@RequestMapping("TransactionAuto")
public class PersonTransationAutoCommit {
    @Autowired
    private TransactionTemplate transactionTemplate;

    @RequestMapping("show")
    public void show(String name) {
        System.out.println("Thread.currentThread().getName() = " + Thread.currentThread().getName());
        System.out.println("======>show...");

        transactionTemplate.executeWithoutResult(status -> {//无返回值
            System.out.println(">>>>>>数据库操作");

            transactionTemplate.execute(status1 -> {//有返回值
                System.out.println(">>>>>>数据库操作");
                return null;
            });

        });
    }
}

声明式事务

@Transactional(rollbackFor = Exception.class)
