我对 Spring MVC 有一个奇怪的问题。我有一个控制器方法,它接受 2 个日期参数作为请求参数startDateendDate. 如果我使用带有 2 个参数的简单 url,如下所示:

http://localhost/myapp/videos?startDate=2013-05-10&endDate=2013-06-01.json

我收到此错误消息:

[#|2013-05-27T17:39:01.711+0200|INFO|glassfish3.1.2|javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=24;_ThreadName=Thread-2;|38386 [http-thread-pool-8080(5)] DEBUG org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver  - Resolving exception from handler [public java.util.List<Video> com.ufasoli.Videos.programs(com.ufasoli.filtering.SearchParams)]: org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors

|#]

但是一旦我删除了.json这样的东西:

http://localhost/myapp/videos?startDate=2013-05-10&endDate=2013-06-01

一切正常...

这对我来说似乎是一个错误,因为数据绑定器在将数据绑定到控制器时不应考虑 url 扩展名,或者这是正常行为吗?

以下是导致问题的控制器方法:

 @RequestMapping(value = "/videos/", 
                 method = RequestMethod.GET, 
                 produces = MediaType.APPLICATION_JSON_VALUE)
    public List<Videos> videos( SearchParams searchParams) {

        return videosRepository.videos(searchParams);
    }

这是我的 SearchParams 类:

public class SearchParams extends BaseSearchParams implements Serializable{


    private static final long serialVersionUID = 1L;
    @DateTimeFormat(iso = ISO.DATE, pattern = "yyyy-MM-dd")
    private Date startDate;
    @DateTimeFormat(iso = ISO.DATE, pattern = "yyyy-MM-dd")
    private Date endDate;

     //Setters/Getters
}

我正在使用 Spring MVC 3.2.1.RELEASE

有什么见解吗?

我认为'url扩展'(如果有的话)应该是路径的一部分,因此在查询之前属于:http://localhost/myapp/videos.json?startDate=2013-05-10&endDate=2013-06-01.
