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

原文：http://pimin.net/archives/432

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

缘由：在调试Spring Data Elasticsearch的时候，希望在查询的时候实现分页查询。传统的方式就是在Controller的参数表中自己获取分页信息，然后组装成Pageable。在Spring Data Elasticsearch官方文档介绍有两种自动化方案：

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

官方介绍说可以注册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>

 

很遗憾，使用这两种方法后直接报错：

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)

 

解决方案，那就是在web-context.xml加入下面的代码

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