Spring如何实现事务管理

我的方法如下

@Transactional(rollbackFor = RuntimeException.class, propagation = Propagation.REQUIRED)
@Override
public InwardDTO saveEntity(InwardDTO entity) throws Exception {
    try {
        costCalculation(entity);
        InwardDTO dto = super.saveEntity(entity);
        addStock(dto.getDetails(), dto.getId());
        return dto;
    } catch (Exception ex) {
        throw ex;
    }
}

private void addStock(Set<InwardDetailsDTO> argDetailsDTOSet, Long argInwardId) throws RuntimeException {
    String SUBMODULE = getModuleNameForLog() + " [addStock()] ";

    if (1 == 1) {
        throw new RuntimeException("Test Case");
    }
}

日志就像，

在此事务中始终在 addStock 方法回滚之前提交... 在日志中显示事务正在回滚，但条目保存在数据库中......

【问题讨论】：

我没有看到任何@Transactional。你能粘贴更多代码吗？
删除 catch try-catch 块。此外，您正在 rollbackFor = Exception.class 并抛出 RuntimeException。
@Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED) @Override public InwardDTO saveEntity(InwardDTO entity) throws Exception { try { costCalculation(entity); InwardDTO dto = super.saveEntity(entity); addStock(dto.getDetails(), dto.getId());返回 dto; } catch (Exception ex) { throw ex; } }
仍然无法工作@dassum
分享修改后的代码也将propagation = Propagation.SUPPORTS改为propagation = Propagation.REQUIRED

【解决方案1】：

Spring 事务 bean 所需列表：

1.Jdbc模板

@Bean(name = "jdbcTemplate")
public JdbcTemplate creatJdbcTemplate(@Qualifier("dataSource") DataSource dataSource) {
    return new JdbcTemplate(dataSource);
}

2.数据源

@Bean(name = "dataSource")
public DataSource creatDataSource() {
    DriverManagerDataSource ds = new DriverManagerDataSource();
    ds.setDriverClassName(driverClassName);
    ds.setUrl(url);
    ds.setUsername(username);
    ds.setPassword(password);
    return ds;
}

3.事务管理器

@Bean(name = "transactionManager")
public PlatformTransactionManager creatTransactionManager(DataSource  dataSource) {
    return new DataSourceTransactionManager(dataSource);
}

4.@EnableTransactionManagement以上一个@Configuration Class激活TxManager

5.使用DaoImplements中的JdbcTemplate的实例(@Autowired)，用query()执行sql || update()方法

【解决方案2】：

如果表存储引擎是MyISAM：这个引擎不支持事务。正确的应该是InnoDB。

如果您使用 Hibernate 自动创建表：我建议您编写自己的迁移并使用像 Flyway 这样的工具来管理这些。这需要更多的工作，但您可以完全控制表格的外观。
