1．错误：object references an unsaved transient instance - save the transient instance before flushing:
com.xxxx.bean.java.Sysblog; nested exception is org.hibernate.TransientObjectException: object references an unsaved
transient instance - save the transient instance before flushing: com.xxx.bean.java.Sysblog
解决方法：没有可预期的实例，当然就要实例化对象咯
2．错误：Exceptionobject references an unsaved transient instance - save the transient instance before flushing:
src.persistent.Product......
解决方法：原因没有为某对象进行set设置， 如上边的这个就是某对象没有调用setProduct
3.错误：Illegal attempt to associate a collection with two open sessions......
解决方法：(hibernate的session提供了一级缓存，每个session，对同一个id进行两次load，不会发送两条sql给数据库，但是session关闭的
时候，一级缓存就失效了。
sysblogarticle.setAmount(new Long(sysblogcommentService.selcom(
sysblogarticle.getArticleid().toString()).size()));//通过文章id获取文章评论数
sysblogarticle.setSysblogcomments(null);//关键
sysblogarticleService.saveOrUpdate(sysblogarticle);//将文章中评论条数修改
参考：http://javaflasher.iteye.com/blog/forum/17913
4.错误：Hbm映射文件都生成好后，改数据库增加了默认值（如：将某个字段值设为1），结果在插入的时候，数据库那边没有反应。
解决方法: 在sql-type里面定义数据库默认值，那么SchemeExport的时候，DDL就会加上default。然后hbm定义为dynamic-insert="true"和
dynamic-update="true"
<hibernate-mapping>
<class name="com.tom.hibernate.EbayItem" table="EBAY_ITEM" schema="API_USER" dynamic-insert="true" dynamic-update="true">
.......
........
<property name="viewData" not-null="true" type="boolean">
<column name="viewdata" sql-type="number(1) default 0"/>
</property>
</class>
</hibernate-mapping>
5.错误：

————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
7.错误
org.springframework.orm.hibernate3.HibernateQueryException: could not resolve property: trackDate of:

————还有nd trt.trackDate=? 语句中的值有误。
8.错误
java.lang.ClassCastException: ookj.domain.OokjDateTime
————基本的 类型转换错误
9.错误

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。

偶嘀错误集合 [转贴 2007-03-04 15:19:00]
1. 做Hibernate多对一的时候遇到错误
(1)org.apache.jasper.JasperException: Error creating bean with name 'sf' defined in ServletContext resource [/WEB-
INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.hibernate.PropertyNotFoundException:
Could not find a getter for person in class com.accp.vo.Course
因为配置文件中的一个 <many-to-one name="person" ../> 中的person属性名称写错了.
还有原因如下:
1)getter()方法写错了,没有按照javaBean的规则写.
2)*.hmb.xml中的属性名和pojo中的是否一致.注意:属性名是否多了空格.
(2).Hibernate多对一报错:
save the transient instance before flushing
具体错误为在one-to-many中，对many进行save时，由于没有加入one的外建，导致错误。
具体解决方法：
（1）、在one的hbm文件中 invest=true
（2）、在many保存前务必要求one的存在
2.spring+struts+hibernate 项目debug总结
(1) javax.servlet.ServletException: Cannot retrieve mapping for action /companyNews
struts-config.xml中没有写相关companyNews的action.
(2) 在myeclipse增加一个jar包时候，先打开项目properties,选择java build path --> libraries -->add external JARs 选择到需要的
jar包，加入后，发现，他这个包加载的是绝对路径，而我们的项目需要cvs共享，无法commit到cvs服务器。myeclipse有以下提示信息：
2 build path entries are missing.
解决办法是，关闭myeclipse,用notepad打开项目目录下的 .classpath, 手动修改成相对路径，并且检 查，指定的相对路径中是否真正添
加了jar包，启动myeclipse就可以上传新添加的jar包了。
(3) 在使用junit/StrutsTest时候，报错：
java.lang.UnsupportedClassVersionError: junit/framework/TestListener (Unsupported major.minor version 49.0)
原因是如果是jdk1.4的话，只能使用junit3.8以下版本，如果是使用jdk1.5的话，必须使用junit4.0 以上版本。
(4) Cannot find ActionMappings or ActionformBeans collection
原因是：web.xml文件中没有配置struts-config.xml的相关信息。
(5) org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jstl/core cannot be resolved in either web.xml
or the jar files deployed with this application
缺少jstl的相关jar和web.xml配置

(5) Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV
standard.jar没有放在lib里面
(6) 创建oracle表的时候，使用了，role和comment关键字，建议不要将这两个关键字作为表名和字段名。
建议用toad或plsql developer创建表，这样软件会提示关键字。
(7) [ERROR] XMLHelper - Error parsing XML: XML InputStream(18) Attribute name "column" associated with an element type "key"
must be followed by the ' = ' character.
[ERROR] Configuration - Could not configure datastore from input stream <org.dom4j.DocumentException: Error on line 18 of

character. Nested exception: Attribute name "column" associated with an element
type "key" must be followed by the ' = ' character.
xml 语法错误，key语法中应该类似这样的写法 <key column="id">
(8) hibernate3,对象中一对多的one方，必须写private Set pays=new HashSet();，否则包错java.lang.NullPointerException ，
而hibernate2中private Set pays;却不报错；
(9) [DEBUG] AbstractSaveEventListener - generated identifier: 1, using strategy: org.hibernate.id.IncrementGenerator
org.hibernate.PropertyValueException: not-null property references a null or transient value: com.xxx.yyy.company
at org.hibernate.engine.Nullability.checkNullability(Nullability.java:72)
<many to one >中的设置应该设置为not-null="false" ，设置为not-null="true"则报以上错误
(10) org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance
before flushing: com.xxx.yyy.Company
在save的同时也需要save其他的表，然后再flush()
(11) Parse Fatal Error at line 12 column 1
struts-config.xml文件被修改，语法错误。检查语法。
(12)org.hibernate.QueryException: could not resolve property: userid of:
com.xxx.yyy.Pay
使用到外键userid的时候，必须使用userinfo.userid方法才能得到。
(13)javax.naming.NameNotFoundException: Name hibernate_connection_factory is not
bound in this Context 原因：hibernate的数据库映射.xml文件有配置错误，导致hibernate_connection_factory无法绑定数据库。
例如many-to-one设置了以后，仍然在其中设置相冲突的<property>属性。
(14) [WARN] RequestProcessor - Unhandled Exception thrown: class java.lang.NullPointerException
必须将使用到的对象new起来。
(15) GROUP BY 表达式的查询必须满足如下：
select 子句后的每一项必需出现在group by 子句中，除非该项使用了聚集函数。
(16) org.hibernate.TransientObjectException: object references an unsaved transient
instance - save the transient instance before flushing: com.xxx.yyy.Company
要级联保存，多次session.save()
(17)
java.lang.IllegalArgumentException: id to load is required for loading
原因：
session.load(Company.class,payForm.getCompanyId());
load()方法第二个参数必须是searlizable,并且必须是和数据库映射类的属性值类型一致，即使强制转换都不行。
(18) [INFO] DefaultLoadEventListener - Error performing load command <org.hibernate.ObjectNotFoundException: No row with the
given identifier exists: [com.xxx.yyy.Company#0]
>org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.xxx.yyy.Company#0]
表示你现在查询的对象所关联的对象有问题，一般是因为数据的问题（该对象所关联的对象找不到）,数据的错误，影响了程序正常执行。
(19)
eclipse 3.1,myeclipse 4错误
Deployment is out of date due to changes in the underlying project contents . You'll need to mannally 'Redeploy' the project
to update the deployed archive.
原因
tomcat 中部署的某个文件的拒绝访问影响了部署。
重启后，去除tomcat中部署的文件。重新在eclipse中设置部署。
为什么需要重启？
因为：google desktop软件正在对我部署的一个300MB大文件进行索引，锁定了这个大文件，我估计google desktop需要对这个文件索引半个小
时以上。因此，eclipse无法对过去部署的文件，做先删除后重新部署的工作。
(20) ERROR LazyInitializationException:19 - could not initialize proxy - the owning Session was closed
org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed
解决办法。
cmpy=(CompanyEdit)ss.load(CompanyEdit.class,companyId1);
Hibernate.initialize(cmpy);//强制初始化cmpy,否则ss.close()后,cmpy将消失.
(21) javascript错误
行: 56
字符: 45
错误: 未结束的字符串常量
代码: 0
是编码的问题！用ANSI编码另存后就好了。
(22) [WARN] JDBCExceptionReporter - SQL Error: 904, SQLState: 42000
[ERROR] JDBCExceptionReporter - ORA-00904: 无效列名 [INFO] DefaultLoadEventListener - Error performing load command

***.hbm.xml文件中的某个列名和数据库中的不同。
(23) ConnectionManager - unclosed connection, forgot to call close() on your session?
原因：没有关闭hibernate的session的transaction。或者没有关闭session
(24) [WARN] SellCommentDAO - org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove
deleted object from associations): [com.xxx.yyy.SellComment#7]
原因：父亲对象（one方）设置cascade="save-update" 时，直接删除子对象时，会报错，
处理方法：save信息需要级联操作，delete时候也要用相同的原理。
SellComment sellComment=new SellComment();
sellComment = (SellComment)session.load(SellComment.class,sellCommentId);//获取儿子对象
Long sellInfoId=sellComment.getSellInfo().getSellId();//获取父亲id
SellInfo sellinfo=(SellInfo)session.load(SellInfo.class,sellInfoId);//获取父亲对象
sellInfo.getSellComments().remove(sellComment);//断绝父子关系
sellComment.setSellInfo(null);//断绝子父关系
session.delete(sellComment);//删除儿子

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。
