Could not instantiate bean class [org.springframework.data.domain.Pageable]: Specified class is an interface解決方案

原文：http://pimin.net/archives/432

環境：Eclipse LUNA、Spring 4.1.1、或Spring 4.3.3、Spring Data Elasticsearch 1.1.0

緣由：在調試Spring Data Elasticsearch的時候，希望在查詢的時候實現分頁查詢。傳統的方式就是在Controller的參數表中自己獲取分頁信息，然后組裝成Pageable。在Spring Data Elasticsearch官方文檔介紹有兩種自動化方案：

1、使用<bean class=”org.springframework.data.web.config.SpringDataWebConfiguration” />

官方介紹說可以注冊DomainClassConverter和HandlerMethodArgumentResolver。

2、配置org.springframework.data.web.PageableHandlerMethodArgumentResolver

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="customArgumentResolvers">
<list>
<bean class="org.springframework.data.web.PageableHandlerMethodArgumentResolver" />
</list>
</property>
</bean>

 

很遺憾，使用這兩種方法后直接報錯：

org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:978)
org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:857)
javax.servlet.http.HttpServlet.service(HttpServlet.java:620)
org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:842)
javax.servlet.http.HttpServlet.service(HttpServlet.java:727)
org.springframework.web.filter.HttpPutFormContentFilter.doFilterInternal(HttpPutFormContentFilter.java:88)
org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)
org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:88)
org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)

 

解決方案，那就是在web-context.xml加入下面的代碼

<mvc:annotation-driven>
<mvc:argument-resolvers>
<bean class="org.springframework.data.web.PageableHandlerMethodArgumentResolver" />
</mvc:argument-resolvers>
</mvc:annotation-driven>
