hibernate 常见的几个问题（一）

2008-2-2 9:45:13 org.hibernate.util.JDBCExceptionReporter logExceptions
严重: Unknown column 'tjsaleresu0_.isupdate' in 'field list'
2008-2-2 9:45:13 org.hibernate.event.def.DefaultLoadEventListener onLoad
信息: Error performing load command
org.hibernate.exception.SQLGrammarException: could not load an entity: [ookj.domain.TjSaleResult#293]

--数据库中没有“isupdate”字段

警告: SQL Error: 1052, SQLState: 23000
2008-2-2 9:51:42 org.hibernate.util.JDBCExceptionReporter logExceptions
严重: Column 'df' in where clause is ambiguous

————find("select tsr from TjSaleResult tsr, TjItemResult tir where tsr=tir.saleResultId and tir=? and df<>1", new Object[]{tir});
————语句中的df不能确定是哪个表的

 

org.springframework.orm.hibernate3.HibernateQueryException: could not resolve property: trackDate of: ookj.domain.TjReagentTrack [from ookj.domain.TjReagentTrack trt where trt.trackStage=? and trt.trackDate=? and trt.userId=? and trt.df<>1]; nested exception is org.hibernate.QueryException: could not resolve property: trackDate of: ookj.domain.TjReagentTrack [from ookj.domain.TjReagentTrack trt where trt.trackStage=? and trt.trackDate=? and trt.userId=? and trt.df<>1]
Caused by: org.hibernate.QueryException: could not resolve property: trackDate of: ookj.domain.TjReagentTrack [from ookj.domain.TjReagentTrack trt where trt.trackStage=? and trt.trackDate=? and trt.userId=? and trt.df<>1]

————问题是配置中：
       private static String[][] properties={
          {"getReagentTrackId","reagent_trackid","0"},
          {"getReagentId","reagentid","1"},
          {"getUserId","userid","1"},
          {"getGuideBookId","guidebookid","1"},
          {"getTrackTime","tracktime","0"},                //这里名称不对
          {"trackStage","trackstage","0"},
          {"getDf","df","0"}
————还有nd trt.trackDate=? 语句中的值有误。

 

java.lang.ClassCastException: ookj.domain.OokjDateTime

————基本的  类型转换错误

 

 

  String sql = "from TjReagentTrack trt where trt.trackStage=? and trt.trackTime like ? and trt.userId=? and trt.df<>1";
  List<TjReagentTrack> list_reagenttrack = srs.find(sql, new Object[]{TjReagentTrack.TRACKSTAGE_QU, "%"+new OokjDate(new Date()).toString()+"%", su});

 

  ApplicationInstance.getActive().setFocusedComponent(textField_Register);

————Echo2焦点问题

org.springframework.dao.InvalidDataAccessApiUsageException: object references an unsaved transient instance - save the transient instance before flushing: ookj.domain.SmDept; nested exception is org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: ookj.domain.SmDept
Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: ookj.domain.SmDept

————new了一个新对象，在未保存之前将它保存进了一个新new的对象。

 

 

 

 

 

 

问题1，quartz 1.6 配置问题。需要使用common-collection-1.3.jar

org.hibernate.type.SerializationException could not deserialize;

我用的数据库是mysql，在通过pojo类自动生成的类中，未为字段指定type，hibernate对自动为其指定，如果它所生成的type不能被反序列化，就会抛出java.util.ServilizableException

比如我产生异常的原因是我建立了一个string[]类型的字段，但在对应的.hbm.xml文件中我没有显式定义它的类型，hibernate自动为其指定了类型，该类型不能被反序列化。

_____多了一个点

 

java.net.SocketException: java.net.ConnectException: Connection refused: connect

————数据库未启动

 

 

严重: Servlet.service() for servlet tijianServlet threw exception
java.lang.IndexOutOfBoundsException: Remember that ordinal parameters are 1-based!

————忘了怎么解决的了，反正不是大问题。

 

 

严重: Servlet.service() for servlet tijianServlet threw exception
java.lang.NoSuchMethodError: ookj.service.SendReagentService.saveTjSendReagent(Lookj/domain/TjReagent;Lookj/domain/SaleGuideBook;)[Ljava/lang/String;

 

————Tomcat\Java虚拟集中代码未跟上，不能保持同步，重启虚拟机就好了。

————配置文件hbr.xml中写的tj_sendreagent字段，在数据库中找不到。

 

 

1,TextField控件textField_Maker.setEnabled(false);为禁用true为可用。

2,
  GroupBox groupBox_GeRenJiHuo = new GroupBox();
  groupBox_GeRenJiHuo.setWidth(new Extent(300, Extent.PX));
  groupBox_GeRenJiHuo.setTitle("个人预约激活");
  RowLayoutData groupBox_GeRenJiHuoLayoutData = new RowLayoutData();
  groupBox_GeRenJiHuoLayoutData.setInsets(new Insets(new Extent(20,
    Extent.PX)));
  groupBox_GeRenJiHuo.setLayoutData(groupBox_GeRenJiHuoLayoutData);
  row_JiHuo.add(groupBox_GeRenJiHuo);
  GroupBox groupBox_TuanDuiJiHuo = new GroupBox();
  groupBox_TuanDuiJiHuo.setWidth(new Extent(300, Extent.PX));
  groupBox_TuanDuiJiHuo.setTitle("团队预约激活");
  groupBox_TuanDuiJiHuo.setInsets(new Insets(new Extent(20, Extent.PX)));
  row_JiHuo.add(groupBox_TuanDuiJiHuo);

第二个是内部20的间隙。第一个没表现。
