Spring Framework @pathvariable Map参数上的HATEOAS链接失败

时间:2016-10-24 15:11:47

标签: java rest spring-mvc spring-hateoas

我正在使用Spring-mvc和Spring hateoas框架编写ReST API。我正在努力创造一个“自我”。链接到具有@pathvariable Map作为参数的方法。我想要为方法允许多个路径变量(并且它可能在将来增长),并且在方法中我试图根据变量的存在或不存在来解决单独的路径。这一切都正常,直到我尝试创建一个自我链接。

我收到了异常

出现意外错误

  

type =内部服务器错误,状态= 500)。没有发现转换器能够   从类型转换   [@ org.springframework.web.bind.annotation.PathVariable   输入java.util.Map]   [java.lang.String中]

这是我的方法

@RequestMapping(value={"/subs","/masterclient/{masterclient}/subs"}, 
    method = RequestMethod.GET)

   public List<Jobs>  getJobList(
         @PathVariable  Map<String, String> pathVariables,
         @RequestParam(value="count", required = false) int count) 
   {

      if (pathVariables.containsKey("masterclient")) 
      {
         System.out.println("Master Client = " +
                         pathVariables.get("masterclient"));
      } 
      else 
      {
         System.out.println("No Master Client");
      }



      //Add a Link to the self here.
      List list = new ArrayList<Jobs>();
           list.add(linkTo(methodOn(ControllerJobs.class).getJobList(pathVariables, count)).withSelfRel());

      return list;
   }
