事务注解

Usage

传播机制

export class Foo {
  @Transactional({ propagation: PropagationType.ALWAYS_NEW })
  async bar() {
    await this.foo();
  }

  @Transactional({ propagation: PropagationType.REQUIRED })
  async foo(msg) {
    console.log('has msg: ', msg);
  }
}

数据源

export class Bar {
  @Transactional({ dataSourceName: 'xx' })
  async bar() {
    await this.foo();
  }
}

Foo.bar 始终会在一个独立的事务中执行，而 Foo.foo 会在 Foo.bar 的事务中执行
