1) 错误：The prefix "context" for element "context:property-placeholder" is not bound.
解决：在文件头中引入：xmlns:context="http://www.springframework.org/schema/context" 就可以。
正解样例：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"
default-autowire="byName">
<context:property-placeholder location="classpath:META-INF/app.properties" />
2) 错误：Cannot convert value of type [org.springframework.jdbc.datasource.DriverManagerDataSource] to required type [com.ibatis.sqlmap.client.SqlMapClient] for property 'sqlMapClient': no matching editors or conversion strategy found
原因：property sqlMapClient 引错了id；一開始ref的不是baikeZhangzishiSqlMapClientReadonly，而是baikeZhangzishiDataSourceReadonly
正解：
<bean id="baikeZhangzishiReadTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate" destroy-method="close">
<property name="sqlMapClient"><ref bean="baikeZhangzishiSqlMapClientReadonly" /></property>
</bean>
<bean id="baikeZhangzishiDataSourceReadonly" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/mysqlAppsDataSourceReadonly</value>
</property>
</bean>
<bean id="baikeZhangzishiSqlMapClientReadonly" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation">
<value>classpath:/ibatis/baikeZhangzishi-sqlmap.xml</value>
</property>
<property name="dataSource" ref="baikeZhangzishiDataSourceReadonly"></property>
</bean>
3)有例如以下两个错误：
错误1:com.ibatis.sqlmap.client.SqlMapException: There is no statement named MS-APPBAIKEZHANGZISHI-ADDINFO in this SqlMap.
错误2：java.lang.NullPointerException
at com.hudong.apps.baikesurvey.dao.impl.BaikeZhangzishiWriteDAOImpl.addBaikeZhangzishi(BaikeZhangzishiWriteDAOImpl.java:29)
at com.hudong.apps.baikesurvey.dao.test.BaikeZhangzishiDAOTest.testAdd(BaikeZhangzishiDAOTest.java:81)
at org.springframework.test.context.junit4.SpringTestMethod.invoke(SpringTestMethod.java:163)
分析：从表面上看，这两个错误系属一个错误，都是sqlMap找不到，可能是相关的xml配置找不到，也可能是id错误，也可能是set注入错误；
我犯得错误是set注入错误，所以在做一些底层东西copy的时候一定要注意这些细节，看看id有没有负责后忘了更改，从而导致set注入相关的spring id，还应该注意的是假设原project使用了高度封装，比方创建一个basedao 存放一些set注入等信息的时候，这时候copy的东西一定要去这个base类中加入对应的模块，比方set注入模块
4)1ibatis错误
com.ibatis.sqlmap.client.SqlMapException: There is no statement named MS-QUERY-TOP-PAGE in this SqlMap.
at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.getMappedStatement(SqlMapExecutorDelegate.java:231)

at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.queryForList(SqlMapExecutorDelegate.java:541)
错误分析：ibatis+spring+jndi+resin使用的使用一定要注意一些配置上面的细节；我这里所犯的错误是由于ibatis配置引用底层sqlxml的时候没有放到sqlMapConfig中；注意jndi的配置不能直接引用ibatis的底层sql文件，必须引用有sqlMapConfig配置的xml文件；
错误例如以下：
jndi 直接引用sql的xml；
<!-- dataSource readonly -->
......
<bean id="topSqlMapClientReadonly" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation">
<value>classpath:/ibatis/com/hudong/apps/baikesurvey/sqlmap/top1000-readonly-sqlmap-mapping.xml</value>
</property>
<property name="dataSource" ref="topDataSourceReadonly"></property>
</bean>
......
正确使用：
<!-- dataSource readonly -->
<bean id="topDataSourceReadonly" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/mysqlDataSourceReadonly</value>
</property>
</bean>
<bean id="topSqlMapClientReadonly" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation">
<value>classpath:/ibatis/baikeSurvey-sqlmap.xml</value>
</property>
<property name="dataSource" ref="topDataSourceReadonly"></property>
</bean>
<bean id="topReadTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate" destroy-method="close">
<property name="sqlMapClient"><ref bean="topSqlMapClientReadonly"/></property>
</bean>
注意ibatis的sqlmap配置，一定要放入sqlMapConfig中；这里另一点要注意的，那就是useStatementNamespaces命名空间的配置，这里假设设置成了false，那么底层sql配置文件就能够不配置命名空间；假设设置成了true，那么必须配置命名空间，否则也会出现这个错误
