注意writer的參數有多個,特別是有一個boolean的參數決定刷新或在附加文本

輸出的結果示例:
1、org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.xindeco.business.pojo.NonageRegister#82]
?at org.hibernate.ObjectNotFoundException.throwIfNull(ObjectNotFoundException.java:27)
?at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:65)
?at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(ApplicationFilterChain.java:252)
?at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)
?at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:672)
?at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:463)
?at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:398)
?at org.apache.catalina.core.ApplicationDispatcher.forward

錯誤的原因：
在nonregsiter中已經手動刪除了id=‘82’的記錄，而在WF_task以及wf-proces中還有bizclass = '3' && bizId = '82'的記錄,只要刪除wf-task中相應的記錄.

ProcessInstance.hbm.xml：

CollRegPI.hbm.xml：


數據庫的數據：

如果bizclass=2是同一種類型的class。由????????
?????????<discriminator
????????????column="bizClass"
????????????type="string"
????????/>來表示。 org.hibernate.hql.QuerySplitter - no persistent classes found for query class:
意味著你沒有將someclass的配置文件放在hibernate.config或沒有寫配置文件。 1,通過構造函數創建bean
2,通過靜態工廠創建bean

其中沒有指定driverManager.createInstance();返回對象的類型，而且createInstance()必須是static方法
3，通過實例工廠方法創建bean
其中father和son必須在同一個bean工廠或父bean工廠，即在同一個applicationcontext或子applicationcontext


二、如果applicationcontext默認預實例化那些singleton　bean，這樣就可以在beanfactory裝載時就檢查出錯誤，而如果singleton　bean設置為lazy－mode， hibernate 保存空值的細節
1。如果字段在pojo類中是復雜對象類型，則在數據庫用nulll表示。
2。如果字段在pojo類中是簡單數據類型，則在數據庫用0表示。 1. document.name.value----->document.all.name.value
2. eval(document.all.name)---->eval('document.all.name')
3.javascript:window.history.go(-1)
4、在action方法中只要拋出exception，就會跳到jspexception頁面中，怎么處理。 為了將業務邏輯放到service層，比如判斷登陸用戶的信息，而在service層無法用SysUser user = (SysUser) request.getSession().getAttribute(WebConstants.SESSION_USER);因此在BaseService設一個屬性為
??????public void setOperator(Entity operator);
??????public Entity getOperator(); ???private static WFEngine instance;
??? public static final WFEngine getInstance() {
??????? return instance;
??? }

<sqlMap namespace="PersonnelRegist">

? <typeAlias alias="ID" type="com.xindeco.core.pojo.IDEntity"/>
? </select>
?? <select id="GraAppInfo.searchUpApply" parameterClass="com.xindeco.business.dto.GraAppInfoDTO"????resultClass="ID" cacheModel="userCache">
?? select distinct a.ID AS id
?? from TGraAppInfo a? left join TEMPLOYUNITBASEINFO b on a.unit=b.MEMBERID
?? where appstatus = '1'
?? <dynamic>
?? <isNotEmpty prepend="AND" property="name">(a.name like '%' + #name# + '%')</isNotEmpty>
?? <isNotEmpty prepend="AND" property="unit">(b.UNITNAME like '%' + #unit# + '%')</isNotEmpty>
?? </dynamic>
? </select>
</sqlMap>

注意sqlmapGraAppInfoDTO的name，unit只能是基本數據類型，不能是復雜數據類型．
２、<script>的位置
<script>
form1.srchEdit.value='<%=srchEdit%>';
form1.srchType.value='<%=srchType%>';????
</script>
<form>
<input type="text" name="srchEdit"/>
<input type="text" name="srchType"/></form>
與<form>
<input type="text" name="srchEdit"/>
<input type="text" name="srchType"/>
</form>
<script>
form1.srchEdit.value='<%=srchEdit%>';
form1.srchType.value='<%=srchType%>';????
</script>
的差別，必須在form加載完對它賦值，否則srchEdit又重新加載，為null

3、hibernate屬性設置出現錯誤：
????? 如果pojo類取fSUnit屬性名，系統將無法識別。get和set將取不到值。

昨天晚上我給他講了英文笑話，雖然他指出了很多錯誤，但那是個好的開始。
???? A redneck bought a tickect and won the lottery.
???? He went to claim it .He said:"I want $20 million right now"
who verified his tickect number replied to him :"No,sir.It doesn't work this way.we give you $1 million today,you will get the rest spread on for the next 19 years."
???? The redneck said:"I want all my money.I won it,and i want it"
????? The man had to explained to him patiently:"you would get $1 million,and the rest during the next 19 years."
????? The redneck ,furious with the man ,screamed out:"I want all my money.If you don't give??me all my money ,i want my dollar back!"
注意讀音：money、million、battle zone。
