DAO 类方法

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());
     }

还有一个例外：

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

当我在没有休眠的情况下使用上述查询并通过在 JDBC 中插入查询时，数据被正确插入。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。因为“stop_id”在应用程序中是 int 类型，而 db 中对应的“id”是 int 类型。

请帮我。提前致谢。

您的实体类和映射文件之间存在一些不匹配，例如fontType/ FONT_TYPE。fontType字段的类型是int，而在 hbm 文件中则映射到java.lang.String.

请查找任何其他类似的不匹配并修复它们。之后，您不应再收到该错误。
