org.springframework.beans.NotWritablePropertyException

问题：

org.springframework.beans.NotWritablePropertyException:Invalid property 'recommendBusinessLogic' of bean class[cn.cnr.cms.api.resource.v1.specialTopic.SpecialTopicResource]: Bean property'recommendBusinessLogic' is not writable or has an invalid setter method. Doesthe parameter type of the setter match the return type of the getter?

解决：

我的ctx-api-resource.xml文件的相关如下：

<bean id="specialTopicResource"
class="cn.cnr.cms.api.resource.v1.specialTopic.SpecialTopicResource"
scope="singleton">
<property name="specialTopicConversionServiceFacade" ref="specialTopicConversionServiceFacade" />
<property name="specialTopicBusinessLogic" ref="specialTopicBusinessLogic" />
<property name="recommendBusinessLogic" ref="recommendBusinessLogic" />
<property name="labelBusinessLogic" ref="labelBusinessLogic" />
</bean>

bean里有4个property，而在class文件（即"cn.cnr.cms.api.resource.v1.specialTopic.SpecialTopicResource"）里只有前2个的getter和setter,补足即可。

总结：bean里的property有几个，class文件就必须声明几个的getter和setter！
