关于spring的@Transaction的回滚

Question

如果第一条修改语句失败第二条插入语句回滚该如何处理？

Answer 1

@Transactional(transactionManager = "xxTransactionManager", rollbackFor = Exception.class)
void demo(Model model) throws Exception {
    if (update(model) <= 0) {
        return;
    }
    
    if (insert(model) <= 0) {
        throw new Exception("Failed");
    }
}
