交易无回滚-Spring Boot 2.0 [英] No rollback on transaction - Spring Boot 2.0

问题描述

我对Spring Boot 2.0.0有问题.当我抛出RuntimeException时，它不会回滚事务.我使用具有相同设置的Spring Boot 1.5.9，它可以正常工作.它只是迁移到Spring Boot 2并停止工作.

I have a problem with Spring Boot 2.0.0. When I throw an RuntimeException it is not rollback the transaction. I was using Spring Boot 1.5.9 with the same settings and it worked. It just migrated to Spring Boot 2 and stopped working.

我的配置类:

@Configuration
@EnableJpaRepositories(basePackages = "com.test.repository")
@EnableTransactionManagement
public class DatabaseConfiguration {

    public static final String MODEL_PACKAGE = "com.test.model";

    @Value("${jdbc.url}")
    private String url;

    @Value("${jdbc.username}")
    private String username;

    @Value("${jdbc.password}")
    private String password;

    @Bean
    public DataSource dataSource() throws SQLException {
        org.apache.tomcat.jdbc.pool.DataSource dataSource = new org.apache.tomcat.jdbc.pool.DataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        dataSource.setUrl(this.url);
        dataSource.setUsername(this.username);
        dataSource.setPassword(this.password);
        return dataSource;
    }

    @Bean
    public PlatformTransactionManager transactionManager(DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }

}

我的商务舱:

@Service
public class TestBusinessImpl implements TestBusiness {

    @Override
    @Transactional
    public void save(final Test test) {
        this.testRepository.save(test);

        throw new RuntimeException("Test rollback");
    }

}

有人知道会发生什么吗?

Does anyone know what may be happening?

推荐答案

您正在使用哪种方言?您必须指定spring.jpa.properties.hibernate.dialect

Which dialect are you using? You must be specifying spring.jpa.properties.hibernate.dialect

org.hibernate.dialect.MySQL5Dialect不支持Springboot 2.0 @Transaction

Springboot 2.0 @Transaction doesn't get supported by org.hibernate.dialect.MySQL5Dialect

而是使用org.hibernate.dialect.MySQL5InnoDBDialect

Rather use org.hibernate.dialect.MySQL5InnoDBDialect
