Question

I am trying to pass clusterId=1 as parameter from <a href="http://192.168.11.134:8080/UniconnectConfigurationWeb/nodes?clusterId=1"> and get it into spring mvc controller through @PathParam("clusterId")Integer clusterId. But I'm getting 404 error.

Guide me how to pass parameter through anchor tag and how to hit controller and get the parameter value. I am sharing my code below,

 @RequestMapping(value = "/nodes?clusterId={clusterId}", method = RequestMethod.GET)
     public ModelAndView nodes(@RequestParam("clusterId")Integer clusterId,HttpSession session, HttpServletRequest request) {
         System.out.println(clusterId);
       return dashboard;
      }
    }
<c:url var="myURL" value="http://192.168.11.134:8080/UniconnectConfigurationWeb/nodes">
    <c:param name="clusterId" value="1"/>
</c:url>

这里您使用clusterId作为请求参数，并从客户端传递到服务器端。但是在您的服务器端代码中，您在请求映射注释中使用?clusterId={clusterId}，并且您尝试使用@RequestParam注释接收该请求参数。这里@RequestParam足以接收请求参数。所以，不需要使用这个？clusterId = {clusterId}`，这不是编写服务器端URL的正确方法。

它可以帮助您更好地理解@RequestParam vs @PathVariable

通过<a href=""> and get it to spring mvc controller
