声明：异常类文章主要是记录了我遇到的异常信息及解决方案，解决方案大部分都是百度解决的，（这里只是针对我遇到的做个汇总），特此声明！
Action异常

2016-11-12 15:17:08,931[ERROR][org.apache.struts2.dispatcher.Dispatcher]:Exception occurred during processing request: Unable to instantiate Action, jcxx.web.actions.monitor.MediDepartAction, defined for ‘index‘ in namespace ‘/jcxx/server/monitor/medidepart‘com.sun.proxy.$Proxy22 cannot be cast to jcxx.service.bo.config.feeitem.IBoTDICTCHARGEITEM

　　spring的XML文件中的BO配置

<!--中心药品诊疗维护-->
<bean id="boTDICTCHARGEITEM_Jcxx" parent="txTransactionProxyJcxx">
    <property name="target">
        <bean class="jcxx.service.bo.config.feeitem.impl.BoTDICTCHARGEITEMImpl">
        <constructor-arg index="0" ref="daoTDICTCHARGEITEM_Jcxx"/>
        </bean>
    </property>
</bean>

　　解决方案：

//service层对应的Action引入业务层接口的方法
iBoItem = (IBoTDICTCHARGEITEM) BeansHelp.getBeanInstance("boTDICTCHARGEITEM");
更改为：
iBoItem = (IBoTDICTCHARGEITEM) BeansHelp.getBeanInstance("boTDICTCHARGEITEM_Jcxx");

sqlMap异常

com.ibatis.sqlmap.client.SqlMapException: There is no statement named xnh.config.getTDICTCODE_COUNT_test in this SqlMap.
at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.getMappedStatement(SqlMapExecutorDelegate.java:232)
at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.queryForObject(SqlMapExecutorDelegate.java:510)
at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.queryForObject(SqlMapExecutorDelegate.java:494)
at com.ibatis.sqlmap.engine.impl.SqlMapSessionImpl.queryForObject(SqlMapSessionImpl.java:106)
at com.ibatis.sqlmap.engine.impl.SqlMapClientImpl.queryForObject(SqlMapClientImpl.java:82)
at xnh.service.dao.config.dict.impl.DaoTDICTCODEImpl.getTDICTCODE_COUNT(DaoTDICTCODEImpl.java:53)
at xnh.service.bo.config.dict.impl.BoTDICTCODEImpl.getTDICTCODE_COUNT(BoTDICTCODEImpl.java:58)

　　原因：
　　　　sqlMap是由Dao层实现类调用的sql语句，异常的意思是：在"xnh.config"这个命名空间下没有找到id="getTDICTCODE_COUNT_test"的sql语句

spring异常：

nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property ‘boBASE_ORG_INFOImpl‘ of bean class [com.xyhsoft.demo.service.bo.mq.MQReceiver]: Bean property ‘boBASE_ORG_INFOImpl‘ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

　　spring对应的配置：

<!-- 组织机构维护 -->
<bean id="boBASE_ORG_INFOImpl" class="com.xyhsoft.demo.service.bo.organize.impl.BoBASE_ORG_INFOImpl">
    <constructor-arg index="0" ref="daoBASE_ORG_INFOImpl" />
</bean>
<bean id="daoBASE_ORG_INFOImpl" class="com.xyhsoft.demo.service.dao.organize.impl.DaoBASE_ORG_INFOImpl">
    <property name="sqlMapClient" ref="sqlMapClient" />
</bean>

　　原因：
　　　　MQReceiver.java类没有set注入"boBASE_ORG_INFOImpl"
解决方案：

// 组织机构
private IBoBASE_ORG_INFO boBASE_ORG_INFOImpl;
/**
* @param boBASE_ORG_INFOImpl
*/
public void setBoBASE_ORG_INFOImpl(IBoBASE_ORG_INFO boBASE_ORG_INFOImpl) {
    this.boBASE_ORG_INFOImpl = boBASE_ORG_INFOImpl;
}

异常四（Dao层实现类出异常）

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘userDao‘ defined in class path resource [com/config/userConfig.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property ‘sqlMapClient‘ of bean class [com.service.user.dao.impl.DaoUser]: Bean property ‘sqlMapClient‘ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

解决方案：
　　dao实现类没有继承extends SqlMapClientDaoSupport
异常五（Bo层实现类出异常）

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘userBiz‘ defined in class path resource [com/config/userConfig.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property ‘userDao‘ of bean class [com.service.user.bo.impl.BoUser]: Bean property ‘userDao‘ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

解决方案：
　　spring的配置文件中，name值与要调用该对象声明的属性名保持一致

<!-- 配置Bo,调Dao -->
<bean id="userBo" class="com.service.user.bo.impl.BoUser">
<!-- 此处的name值，必须与业务层实现类声明的Dao层的属性名相同 -->
　　<property name="daoUser" ref="userDao"/>
</bean>

　　Bo层

//调用dao层用户类,spring托管实例化
private IDaoUser daoUser;
public void setDaoUser(IDaoUser daoUserImpl) {
    this.daoUser = daoUserImpl;
}

异常六（set注入异常）

Caused by: org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type [com.sun.proxy.$Proxy9 implementing com.xyhsoft.demo.service.bo.dictionary.IBoBASE_DICTIONARY,
org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.xyhsoft.demo.service.bo.organize.IBoBASE_ORG_INFO] for property ‘boBASE_DICTIONARYImpl‘;
nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.sun.proxy.$Proxy9 implementing com.xyhsoft.demo.service.bo.dictionary.IBoBASE_DICTIONARY,
org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.xyhsoft.demo.service.bo.organize.IBoBASE_ORG_INFO] for property ‘boBASE_DICTIONARYImpl‘: no matching editors or conversion strategy found

　　原因：

// 组织机构
private IBoBASE_ORG_INFO boBASE_ORG_INFOImpl;
// 字典管理
private IBoBASE_ORG_INFO boBASE_DICTIONARYImpl;

public void setBoBASE_DICTIONARYImpl(IBoBASE_ORG_INFO boBASE_DICTIONARYImpl) {
    this.boBASE_DICTIONARYImpl = boBASE_DICTIONARYImpl;
}

public void setBoBASE_ORG_INFOImpl(IBoBASE_ORG_INFO boBASE_ORG_INFOImpl) {
    this.boBASE_ORG_INFOImpl = boBASE_ORG_INFOImpl;
}

　　声明重复：同一个变量类型：IBoBASE_ORG_INFO ，不同的变量名和set方法
