 把student类中的id的set和get方法贴出来看看

说的是非法参数异常 student的id

at dao.student.StudentDAOImpl.findStudentList(StudentDAOImpl.java:70)
at service.student.StudentServiceImpl.findStudentList(StudentServiceImpl.java:14)
at servlet.student.findStudentList.doPost(findStudentList.java:53)
at servlet.student.findStudentList.doGet(findStudentList.java:61)
应该这些地方有什么错吧

List results=cri.setCacheable(true).setFirstResult(firstRow)
.setMaxResults(pageSize)
//.setResultTransformer(DistinctRootEntityResultTransformer.INSTANCE)
.list();

        找到原因了，因为没加注释的那条，但是不知道为什么不加就会报那个非法参数和object那个异常
