1. 如果你一次执行单条查询语句，则没有必要启用事务支持，数据库默认支持 SQL 执行期间的读一致性；
2. 如果你一次执行多条查询语句，例如统计查询，报表查询，在这种场景下，多条查询 SQL 必须保证整体的读一致性，否则，在前条 SQL 查询之后，后条 SQL 查询之前，数据被其他用户改变，则该次整体的统计查询将会出现读数据不一致的状态，此时，应该启用事务支持

#### 3.3.4. 事务回滚规则
#### 3.3.5. 事务回滚规则

这些规则定义了哪些异常会导致事务回滚而哪些不会。默认情况下，事务只有遇到运行期异常（RuntimeException 的子类）时才会回滚，Error 也会导致事务回滚，但是，在遇到检查型（Checked）异常时不会回滚。
