Spring Boot實(shí)現(xiàn)事務(wù)特別特別簡(jiǎn)單，沒有多余操作，一個(gè)注解@Transactional搞定

依賴的Jar包pom.xml

Spring Boot中實(shí)現(xiàn)事務(wù)沒有額外的Jar包，還是基本的數(shù)據(jù)庫(kù)訪問包，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>

注解事務(wù)@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);
    }
}

注解屬性

• rollbackFor：觸發(fā)回滾的異常，默認(rèn)是RuntimeException和Error
• isolation: 事務(wù)的隔離級(jí)別，默認(rèn)是Isolation.DEFAULT也就是數(shù)據(jù)庫(kù)自身的默認(rèn)隔離級(jí)別，比如MySQL是ISOLATION_REPEATABLE_READ可重復(fù)讀

這樣就可以了，不需要其他配置。

ps：網(wǎng)絡(luò)上還說要在@SpringBootApplication上添加注解@EnableTransactionManagement，已經(jīng)不需要了
