DAO CLASS METHOD

public JSONObject getSaveToDatabase(List dataHolder) throws ParseException {
List list= new ArrayList();
     Session sessionOracle=null;
     Pojo Db=new Pojo();
     sessionOracle=BaseDAO.getHibernateSession().openSession();
     org.hibernate.Transaction txOracle=null;

     //list contains record
     Db.setStopID((int)list.get(0));
     System.out.println(Db.getStopID());

     try{

         txOracle=sessionOracle.beginTransaction();
         System.out.println(sessionOracle.isOpen());
         sessionOracle.save(Db);
         txOracle.commit();
         System.out.println("Data is inserted");
          }catch(Exception i){
         txOracle.rollback();
         i.printStackTrace();
         System.out.println("Exception in POI ------"+i.toString());
     }

例外：

Hibernate: insert into POI_M_STOP (stop_id, stop_name, stop_alias_name1, stop_alias_name2, stop_alias_name3, stop_cd, stop_type_id, jurisdiction, mobile_number, del_flag, create_user_id, latitude, longitude, create_time, last_updated_time, district_id, state_id, lat_rounded, lat_rounded_2, lat_rounded_3, long_rounded, long_rounded_2, long_rounded_3, audio_file, stop_name_road, city_type, city_name_id, STOP_NAME_REG_LANG1, STOP_NAME_REG_LANG2, LAST_UPDATED_BY, CREATE_ROLE_ID, UPDATED_ROLE_ID, RADIUS_FOR_DETECTION, FONT_TYPE) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

当我在没有hibernate的情况下使用上述查询并在JDBC中使用插入查询时，正在正确插入数据。我只是检查id列和“session.save（obj）”和“transaction.commit（）; - line（1）”。在第（1）行，它抛出了上述异常。由于“stop_id”在应用程序中的类型为int，而db中相应的“id”的类型为int。

请帮帮我。提前谢谢。

Answer 1

您的实体类与映射文件之间存在一些不匹配，例如： fontType / FONT_TYPE。 fontType字段的类型为int，而在hbm文件中，它会映射到java.lang.String。

请查找任何其他类似的不匹配并修复它们。在那之后，你不应再得到那个错误了。

应该在查询中输入什么
