Try - Double Catch语句Java 、 我遇到了一个问题,无法理解从try - catch语句中得到的错误消息,该语句有两个捕获。我相信一切都是正确的,但是,我得到了一个错误的exception X is never thrown in body of corresponding try statement.我相信代码是正确的,但是两个catch子句都被拒绝了!Consumes("application/json"...
程序运行,结果是InsertCuser中出现异常,导致事务回滚、users表和cuser表均无数据插入。由于两个方法被纳入同一个事务,因此两者都会回滚。即使在cuserService.InsertCuser(cuser);上使用try/catch捕获并不抛出异常也没用(此方法能保证调用者方法中的独立事务不受被调用者抛出的异常影响而回滚) 我们再来看,将上面环境...

即使在cuserService.InsertCuser(cuser);上使用try/catch捕获并不抛出异常也没用(此方法能保证调用者方法中的独立事务不受被调用者抛出的异常影响而回滚) 我们再来看,将上面环境的InsertCuser方法传播行为改成NESTED @Transactional(propagation=Propagation.NESTED) @Override public void InsertCuser(Cuser cuser) {...

Nested Try-Catch Example Similar to the situation with a Try-Finally block, we may sometimes need to nest Try-Catch blocks. As an example, take a look at the code below (taken from this ) : try { transaction.commit(); } catch { logerror(); try { transaction.rollback(); } catch ...
When a try catch block is present in another try block then it is called the nested try catch block. Each time a try block does not have a catch handler for a particular exception, then the catch blocks of parent try block are inspected for that exceptio
c.在主事务中SaleMainService.sale必须使用try..catch来处理独立事务"SaleInfoService.sale"。 当独立事务"SaleInfoService.sale"发生异常的时候,它自己会回滚(spring处理),之后需要捕获这个异常,避免让主事务回滚。 注意:事务代码中,并非不能做异常处理。至于为什么,仔细阅读原生jdbc的事务就明白了。
You cannot define a nested function inside any of the MATLAB®program control statements, such asif/elseif/else,switch/case,for,while, ortry/catch. You must call a nested function either directly by name (without usingfeval), or using a function handle that you created using the@operator ...
首先,你需要在可能抛出"nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLTransactionRollback"异常的代码块中使用try-catch语句捕获该异常。下面是示例代码: try{// 可能抛出异常的代码}catch(NestedTransactionRollbackExceptione){// 处理异常的代码} ...
