Spring Transactional TimeOut
提问by U?ur Ye?ilyurt
I am trying to use spring @Transactionalannotation and timeoutparameter. I basically test the code with put some Thread.sleep()codes. Then i get timeout exception as i expected. Also i want to get timeout exception when database operations take longer than my timeout period. I lock a record in a table in my database with for update select statement. I try to update that record. But program wait and do nothing. Here my sample code.
我正在尝试使用 spring@Transactional注释和timeout参数。我基本上用放置一些Thread.sleep()代码来测试代码。然后我得到了我预期的超时异常。另外，当数据库操作花费的时间超过我的超时时间时，我想获得超时异常。我使用 for update select 语句锁定数据库表中的记录。我尝试更新该记录。但是程序等待什么都不做。这是我的示例代码。
@Transactional(rollbackFor = Exception.class, timeout=5)
public void executeService(List<sendData> list) throws Exception{
List<sendData> newList = gDAO.updateSentList(list);
}
In this case the program should throw timeout exception. How can i fix it?
在这种情况下，程序应该抛出超时异常。我该如何解决？
采纳答案by U?ur Ye?ilyurt
I solved my problem using oracle.jdbc.ReadTimeout=60000on application context. @Transactionalannotation do not work on jdbc read timeout exception.
我oracle.jdbc.ReadTimeout=60000在应用程序上下文中解决了我的问题。@Transactional注释对 jdbc 读取超时异常不起作用。

Finally I found the solution...
最后我找到了解决方案......
Short answer is, that the problem is in a way how you are testing the timeout - Thread.sleep()cannot be used...
简短的回答是，问题在于您如何测试超时 -Thread.sleep()不能使用......
Long answer:
长答案：
What I had to use (because I tested with MySQL) was a real statement - select sleep(5). This call ended with:
我必须使用的（因为我用 MySQL 测试过）是一个真实的声明 - select sleep(5). 本次通话以：

From stack this got my attention:
StatementPreparerImpl$StatementPreparationTemplate.setStatementTimeout(StatementPreparerImpl.java:208)
从堆栈这引起了我的注意：
StatementPreparerImpl$StatementPreparationTemplate.setStatementTimeout(StatementPreparerImpl.java:208)
...so I wanted to try with a different use case
...所以我想尝试不同的用例
@Transactional(timeout=10)
public void mysqlWait() {
System.out.println("timeout: " + sessionFactory.getCurrentSession().getTransaction().getTimeout());
for (int i = 0; i < 6; i++) {
SQLQuery query = sessionFactory.getCurrentSession().createSQLQuery("select sleep(2)");
System.out.println("executed (" + i + "): " + query.uniqueResult());
}
}
and it resulted in:
结果是：
