弹簧mybatis mysql没有回滚

Question

我在Spring中遇到了这个事务。 我不知道为什么永远不会回滚。 有人知道它发生了什么吗？

的web.xml：

    <web-app id="WebApp_ID" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        throw new NullPointerException(); // Error to do the rollback

        fileCab.setnUser("user");   
        fileCab.setiPax(5);
        fileCab.setnNamePax(""); 
        Date dateIn = new Date();

        fileCab.setnYear(String.valueOf(Calendar.getInstance().get(Calendar.YEAR)));                
        fileCab.setdOpenDay(Calendar.getInstance().getTime());              
        fileCab.setiAgency(0);              
        fileCab.setnStatus("Cerrado");
        fileCab.setbPrePaid(0); 
        fileCab.setbPaid(0);
        fileCab.setdDatePrePaid(null); 
        fileCab.setDcPrePaidAmount(BigDecimal.ZERO);
        fileCab.setiTourService(0); 
        fileCab.setnObservations("");

        fileCabService.insertFileCab(fileCab);
    }
}
