添加不回滚属性设置

即便是出现的System.out.println(1/0);这种异常，，但是发生这个错误，你别撤销

如何设置发生错误不撤销

• noRollbackFor:需要异常的类型
• noRollbackForClassName:需要异常的名称(更多用的是这个)

java.lang.ArithmeticException: / by zero

package com.chentianyu.service.impl;
import com.chentianyu.mapper.AccountMapper;
import com.chentianyu.pojo.Account;
import com.chentianyu.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
@Service//业务逻辑层
@Transactional(propagation = Propagation.REQUIRED/*事务的传播特性,增删改必走这个特性*/,
noRollbackForClassName = "ArithmeticException")
public class AccountServiceImpl implements AccountService {
    //但凡是业务逻辑层的实现类，一定会有数据访问层的对象
    @Autowired
    AccountMapper accountMapper;
    @Override
    public int insertAccount(Account account) {
        int num = 0;
        num = accountMapper.insertAccount(account);
        System.out.println("添加用户成功,num="+num);
        //手动抛出异常
        System.out.println(1/0);//出现错误的时候我们不希望数据插入进数据库
        return num;
    }
}

告诉是算数异常别回滚

@Test
public void test02(){
    ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext_service.xml");
    AccountService accountService = (AccountService) ac.getBean("accountServiceImpl");
    System.out.println(accountService.getClass());
    accountService.insertAccount(new Account(100,"张三","添加成功!"));
}

虽然还是异常了，但是数据库中还是添加进了数据

这样子的处理就更加灵活了
