org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'studentAction' defined in class path resource [applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'studentMangerService' of bean class [com.qlst.action.StudentAction]: Bean property 'studentMangerService' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
