加了Tx.class 后，事务不回滚?报错

部分代码如下

其中public static final HydLoan dao = new HydLoan();

@Before(Tx.class)
   public void agreementSave() throws Exception{
    try{
     HydLoan hydLoan = HydLoan.dao.getHydLoan(loan_id);
     hydLoanLog.set("ID", Util.getUUID());
     hydLoanLog.set("loan_id", loan_id);
     hydLoanLog.set("user_id", user_id);
     hydLoanLog.set("realname", realname);
     hydLoanLog.set("bf_loan_status", HydContent.FULL_LOAN);
     hydLoanLog.set("result_status", "CURRENT_PASS");
     hydLoanLog.set("audit_remark", "借贷合同签订");
     hydLoanLog.set("ctime", Util.getFormatDate());
     
     hydLoanLog.save();
     
     hydLoan.set("bf_loan_status", HydContent.SECOND_WAIT_ACCOUNTING);
     hydLoan.set("credit_loan_status", HydContent.SECOND_WAIT_ACCOUNTING);
     hydLoan.set("result_status", "CURRENT_PASS");
     hydLoan.set("back_reason", "借贷合同签订");
     hydLoan.set("desc", "借贷合同签订");     
     hydLoan.update();
    }catch(Exception e){

    throw new Exception("出错了");
    

     }

标红的地方，其实数据库中没有该字段,这必然报错，可是第一个表中却成功插入数据了，第2个表中，却没有修改成功，这是为什么哦？为啥事务没有回滚成功呢？

另外数据库引是 innodb
