org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.view.ContentNegotiatingViewResolver#0' defined in ServletContext resource [/WEB-INF/configs/spring/mvc-dispatcher-servlet.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'viewClass' of bean class [org.springframework.web.servlet.view.ContentNegotiatingViewResolver]: Bean property 'viewClass' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
