ibatis的一些错误码解释以及解决方法、一些使用心得

<script>function StorePage(){d=document;t=d.selection?(d.selection.type!='None'?d.selection.createRange().text:''):(d.getSelection?d.getSelection():'');void(keyit=window.open('http://www.365key.com/storeit.aspx?t='+escape(d.title)+'&u='+escape(d.location.href)+'&c='+escape(t),'keyit','scrollbars=no,width=475,height=575,left=75,top=20,status=no,resizable=yes'));keyit.focus();}</script>

1. --- Cause: java.sql.SQLException: 无效的列类型; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException:
原因:

某个字段的插入值为空

解决方法：

将该字段的数值添加进去，或者将格式转化为动态的sql

2.

com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in com/kompakar/queue/transfusion/dao/ibatis/map/HisInfo.xml.
--- The error occurred while applying a parameter map.
--- Check the getPatientInfoByClinicNo-InlineParameterMap.
--- Check the statement (query failed).
--- Cause: java.sql.SQLException: ORA-01002: 读取违反顺序
ORA-02063: 紧接着line（源于DBLINKFGHIS）

Caused by: java.sql.SQLException: ORA-01002: 读取违反顺序
ORA-02063: 紧接着line（源于DBLINKFGHIS）

原因：

在不应该提交事务的地方，主动提交了事务。用DBLINK方式连接另一个数据库，在IBATIS中必须声明为事务。

解决方法：

将这个方法声明为事务。

3.

错误码：

com.ibatis.common.beans.ProbeException: There is no READABLE property named 'tAlarmlogId' in class 'com.kompakar.queue.transfusion.bo.TAlarmLogBO'

错误原因：

BO文件中定义的变量，中间有大写的，所以在匹配中出错。－－准确的说，是ibatis中的第二个字母不能大写

解决方法：

将BO文件中的所有变量名都修改为小写。

4.org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mraServiceTarget' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'patientMedicalAlertDAO' of bean class [com.kompakar.ehealth.service.impl.mra.MRAService]: Bean property 'patientMedicalAlertDAO' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?
org.springframework.beans.NotWritablePropertyException: Invalid property 'patientMedicalAlertDAO' of bean class [com.kompakar.ehealth.service.impl.mra.MRAService]: Bean property 'patientMedicalAlertDAO' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?
at org.springframework.beans.BeanWrapperImpl.setPropertyValue(BeanWrapperImpl.java:831)

原因：在service中配置了property，但是在具体的service实现类中，却没有声明该property，以及没有实现相应的set和get方法（bean的方法）。

解决方案：

在service的实现类中，增加该属性字段的声明和set、get方法

5、17:12:14,796 ERROR eHealthActionServlet:68 - class com.kompakar.ehealth.common.frame.communicate.eHealthActionServlet Exception occured in performing process(HttpServletRequest request, HttpServletResponse response).
javax.servlet.ServletException: There is no statement named WardMstr-getAllwardList in this SqlMap.

可能原因：
A、在相应的sqlmap配置文件真的没有 “WardMstr-getAllwardList ”
B、在sqlmap配置文件中， 没有引用对应表的配置xml文件。
解决方法：
修改sqlmap相应的配置文件。

6、在sqlmap中，特殊字符需要用 <![CDATA[ ]]>符号将特殊字符括起来
