SPringMVC + hibernate 执行update（） 死也不更新

[qq_34865015]

System.out.println("执行之前");
System.out.println(s.getStudentName());
Transaction tx = sessionFactory.getCurrentSession().beginTransaction();
sessionFactory.getCurrentSession().update(s);
tx.commit();
System.out.println("执行之后");


结果：
执行之前
爱上
执行之后
Hibernate: select count(*) as col_0_0_ from credit_audit_system.c_student cstudent0_ where 1=1
Hibernate: select cstudent0_.student_id as student_1_8_, cstudent0_.class_id as class_id4_8_, cstudent0_.major_id as major_id5_8_, cstudent0_.plan_id as plan_id6_8_, cstudent0_.check_state as check_st2_8_, cstudent0_.student_name as student_3_8_ from credit_audit_system.c_student cstudent0_ where 1=1 limit ?

贴完整代码看看。

sessionFactory.getCurrentSession().update(s); 

执行这个语句前s的值变了吗？

如果启用了二级缓存，对表执行数据库操作，请在最后sessionFactory.getCurrentSession().flush(); 还有sessionFactory的获取请不要重复 声明变量获取一次就好

你是不是开着二级缓存呢？
