Question

我对Hibernate很新，而执行 tx.commit（）我得到了上面提到的异常。我提供了我的POJO类，CFG.XML和 hibernate D A代码，我使用了hibernate 3 jar，并使用Net Beans IDE（7.3）

请仔细检查并让我知道我在哪里犯了错误。

谢谢

  public String saveEnrollmentData(String uid, String jsonString) {
        String output = null; 
        try {
       factory=new AnnotationConfiguration().configure("com/integra/HibernateTest/hibernate.cfg.xml").addAnnotatedClass(EnrollmentBean.class).buildSessionFactory();
	Session session = factory.openSession(); 
	      Transaction tx = null; 
	      tx = session.beginTransaction(); 
	      
	         
	         EnrollmentBean enrollment = new EnrollmentBean(); 
	         enrollment.setUid(uid);
	         enrollment.setJSONDATA(jsonString);
                 session.saveOrUpdate(enrollment);
                
	         tx.commit();
                 output="Updated";
                 
        }catch(Exception ex)

Exception :Could not execute JDBC batch update

Answer 1

根据此页面，名称uid是保留字

Oracle Reserved Words

如果您无法更改表格定义，可以使用它来引用它，例如

@Column (name="`uid`")

我很惊讶您能够使用uid作为列名创建表格。
