马行空：
使用HibernateTransactionManager事务管理器 测试nested场景二方法三时，两个对象都会保存，官方文档表示不支持nested

老师，请问一下，关于2.2的验证方法3，按您文档中写的话，异常被catch不会被外围方法感知，外围方法事务不回滚，故插入“张三”方法插入成功。但是我实际中测试发现“张三”并没有被插入，我用的是jpa测试。
@Test @Transactional(propagation = Propagation.REQUIRED) public void transaction_required_requiresNew_requiresNew_exception_try() { User1 user1 = new User1(); user1.setName("张三"); user1Service.addRequired(user1);
User2 user2 = new User2();
user2.setName("李四");
user2Service.addRequiresNew(user2);
User2 user3 = new User2();
user3.setName("王五");
try {
user2Service.addRequiresNewException(user3);
} catch (Exception e) {
System.out.println("回滚");
}
}
测试代码是这样的。 Hibernate: select next_val as id_val from generator for update Hibernate: update generator set next_val= ? where next_val=? Hibernate: select next_val as id_val from generator for update Hibernate: update generator set next_val= ? where next_val=? Hibernate: insert into user2 (name, id) values (?, ?) Hibernate: select next_val as id_val from generator for update Hibernate: update generator set next_val= ? where next_val=? 回滚 控制台也显示只有一次插入动作。
请问这是为什么呢？
