錯誤，而試圖將數據插入到數據庫中（Spring和Hibernate）

Question

這是錯誤

HTTP Status 500 - Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessResourceUsageException: Could not execute JDBC batch update; SQL [insert into links (category, xdate, desc, tags, xtime, tittle, url, id) values (?, ?, ?, ?, ?, ?, ?, ?)]; nested exception is org.hibernate.exception.SQLGrammarException: Could not execute JDBC batch update

吾道類是

package com.killerlinks.dao; 

import org.hibernate.SessionFactory; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Repository; 

import com.killerlinks.model.Linkform; 

@Repository 
public class LinkformDaoImpl implements LinkformDao 
{ 
    @Autowired 
    SessionFactory sessionFactory; 

    public void insertLink(Linkform linkform) 
    { 
     System.out.println(linkform.getTittle()); 
     System.out.println(linkform.getUrl()); 
     System.out.println(linkform.getCategory()); 
     System.out.println(linkform.getDesc()); 
     System.out.println(linkform.getTags()); 
     System.out.println(linkform.getDate()); 
     System.out.println(linkform.getTime()); 

     sessionFactory.getCurrentSession().saveOrUpdate(linkform); 
    } 

} 

println語句工作正常，當我不插入到數據庫。

sessionFactory.getCurrentSession().saveOrUpdate(linkform); 

當我在上面的程序中使用此語句時出現錯誤。

我Bean類是

    { 
     return "Linkform [tittle=" + tittle + ", url=" + url + ", category="+ category +", tags="+ tags +", desc="+ desc +"]"; 
    } 
} 

請幫我修復這個bug。

Answer 1

列名desc是無效的，因爲它是Oracle中的尊敬詞。解決方法是使用其他名稱作爲列。
