Spring Boot事务回滚

Question

@Repository
public class HibernateDaoImp implements Dao {
    @PersistenceContext 
    private EntityManager entityManager;

    public <T extends AbstractEntity> T saveOrUpdate(T entity) {
        if(entity.getId() == null || entity.getId().equals(0)) {
            this.entityManager.persist(entity);
            t = entity;
        } else {
            t = (T) this.entityManager.merge(entity);
        }
        return t;
    } 
}

@Service("userService")
public class UserServiceImp implements UserService {
    @Autowired
    protected Dao dao;

    @Override
    @Transactional(propagation = Propagation.REQUIRED, rollbackFor = {ServiceException.class})
    public User saveUser(User user) throws ServiceException {
        user = this.dao.saveOrUpdate(user);
        throw new ServiceException(500, "internal error");
    }
}

@Transactional(propagation = Propagation.MANDATORY, rollbackFor = {ServiceException.class})

以下是我在Application.Properties中的数据源设置：

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mytestdb?useSSL=false
spring.datasource.username=abc
spring.datasource.password=abc123

spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.maximum-pool-size=50
spring.datasource.hikari.idle-timeout=1000
spring.datasource.hikari.pool-name=knected-pool

#spring.datasource.tomcat.max-wait=20000
#spring.datasource.tomcat.max-active=50
#spring.datasource.tomcat.max-idle=20
#spring.datasource.tomcat.min-idle=15

spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.id.new_generator_mappings = false

Answer 1

在根据@Kayaman的建议将范围缩小到底层连接之后，我发现org.hibernate.dialt.mysql5Dialcop不支持SpringBoot2.0@Transaction。我改成了Mysql5InnodBDialke，重新创建了表，回滚工作如预期的那样！

我应该在第一时间发布我的数据源配置。

非常感谢@Kayaman和@Sundararaj Govindasamy对您的帮助！
