启动tomcat的时候spring的配置文件报出异常，
我的配置文件是这样定义的，我应用了dao模式，如：
<bean id="okManager" class="com.mytest.OkManagerImpl" autowire="byName">
<property name="youAreOKDAO">
<ref local="youAreOKDAO"/>
</property>
</bean>
<bean id="youAreOKDAO" parent="baseTxProxy">
<property name="target">
<bean class="com.test.dao.YouAreOKDAOImpl" autowire="byName">
<property name="cacheQueries">
<value>true</value>
</property>
</bean>
</property>
</bean>
运行的时候报异常为
Error creating bean with name 'okManager' defined in ServletContext resource [/WEB-INF/applicationContext.xml]:
Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'youAreOKDAO' of bean class [com.caicai.lead21.service.spring.NewsContentServiceSpringImpl]:
Bean property 'youAreOKDAO' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?
在YouAreOKDAOImpl里我已经写了相应的set和get方法，可是就是报错，后来我把dao的名字改成了youareokDAO都是小写，重新部署，之后就不报错了
