私はSpring Restful Serviceを初めて使用し、以下のURLを入力したときに異なる形式で結果を取得したい-----

localhost:7001/SpringRestService/restful/methodName/ALL/ALL/ALL/ALL.xml
localhost:7001/SpringRestService/restful/methodName/ALL/ALL/ALL/ALL.json
localhost:7001/SpringRestService/restful/methodName/ALL/ALL/ALL/ALL.pdf

しかし、サーバーを起動すると以下のエラーが発生します----

 <Servlet: "SpringRest" failed to preload on startup in Web application: "SpringRestService".
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.view.ContentNegotiatingViewResolver#0' defined in ServletContext resource [/WEB-INF/SpringRest-servlet.xml]: Cannot create inner bean 'org.springframework.web.servlet.view.UrlBasedViewResolver#20e0f98' of type [org.springframework.web.servlet.view.UrlBasedViewResolver] while setting bean property 'viewResolvers' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.view.UrlBasedViewResolver#20e0f98' defined in ServletContext resource [/WEB-INF/SpringRest-servlet.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Property 'viewClass' is required

UrlBasedViewResolver の構成が不完全です。例外は、プロパティ「viewClass」が欠落していることを示しています。たとえば、完全な構成:

<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
  <property name="prefix" value="/jsp/"/>
  <property name="suffix" value=".jsp"/>
  <property name="viewClass" 
    value="org.springframework.web.servlet.view.JstlView"/>
</bean>
