默认spring事务只在发生未被捕获的 runtimeExcetpion时才回滚。
spring aop 异常捕获原理：被拦截的方法需显式抛出异常，并不能经任何处理，这样aop代理才能捕获到方法的异常，才能进行回滚，默认情况下aop只捕获runtimeException的异常，但可以通过
1.异常不try { }catch (Exception e){ } 回滚
@Transactional
public ErrorInfotransactionaTest(String no) {
Goods goods=goodsMapper.selectByPrimaryKey(no);
if(goods==null){
return ErrorInfo.inputIsNull();
}
goods.setStatus(2);
goodsMapper.updateByPrimaryKey(goods);
transactionaTest01(goods);
return ErrorInfo.getSuccess();
}
public void transactionaTest01(Goods goods){
goods.setStatus(3);
goodsMapper.updateByPrimaryKey(goods);
int i=1/0;
}
2.异常try { }catch (Exception e){ }，不回滚
@Transactional
public ErrorInfotransactionaTest(String no) {
Goods goods=goodsMapper.selectByPrimaryKey(no);
if(goods==null){
return ErrorInfo.inputIsNull();
}
goods.setStatus(2);
goodsMapper.updateByPrimaryKey(goods);
transactionaTest01(goods);
return ErrorInfo.getSuccess();
}
public void transactionaTest01(Goods goods){
goods.setStatus(3);
goodsMapper.updateByPrimaryKey(goods);
try {
int i=1/0; //捕获异常，不回滚
}catch (Exception e){
}
}
3.异常try { }catch (Exception e){ } 且TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();回滚
@Override
@Transactional
public ErrorInfotransactionaTest(String no) {
Goods goods=goodsMapper.selectByPrimaryKey(no);
if(goods==null){
return ErrorInfo.inputIsNull();
}
goods.setStatus(2);
goodsMapper.updateByPrimaryKey(goods);
transactionaTest01(goods);
return ErrorInfo.getSuccess();
}
public void transactionaTest01(Goods goods){
goods.setStatus(3);
goodsMapper.updateByPrimaryKey(goods);
try {
int i=1/0;
}catch (Exception e){
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); //虽然try了，手动回滚
或者
throw new RuntimeException()；
}
}
