Question

我是spring框架的新手，并尝试使用spring xml创建一个bean，但我现在正面临异常

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'feedServerLineRead' defined in class path resource [FeedServer.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'feedProcessor' of bean class [workflow.FeedServerLineRead]: Bean property 'feedProcessor' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

问题已解决：这是由于使用了不正确的jar。 spring.tx是需要使用的jar，而我使用的是spring.dao

org.springframework.beans.NotWritablePropertyException：bean类的属性'xxxx'无效：
