Spring Boot实现事务特别特别简单，没有多余操作，一个注解
@Transactional搞定
依赖的Jar包pom.xml
Spring Boot中实现事务没有额外的Jar包，还是基本的数据库访问包，比如mybatis
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.13</version>
</dependency>
注解事务@Transactional
@Service
public class PersonService {
@Resource
private PersonMapper personMapper;
@Resource
private CompanyMapper companyMapper;
@Transactional(rollbackFor = {RuntimeException.class, Error.class})
public void saveOne(Person person) {
Company company = new Company();
company.setName("tenmao:" + person.getName());
companyMapper.insertOne(company);
personMapper.insertOne(person);
}
}
注解属性
-
rollbackFor：触发回滚的异常，默认是RuntimeException和Error -
isolation: 事务的隔离级别，默认是Isolation.DEFAULT也就是数据库自身的默认隔离级别，比如MySQL是ISOLATION_REPEATABLE_READ可重复读
这样就可以了，不需要其他配置。
ps：网络上还说要在@SpringBootApplication上添加注解@EnableTransactionManagement，已经不需要了
