问题 Is it possible to make the @PathVariable to return null if the path variable is not in the url? Otherwise I need to make two handlers. One for /simple and another for /simple/{game} , but both do the same just if there is no game defined i pick first one from a list however if there is a game param defined then i use it. @RequestMapping(value = {"/simple", "/simple/{game}"}, method = RequestMethod.GET) public ModelAndView gameHandler(@PathVariable("example") String example, HttpServletRequest

问题 I was trying to install Sencha Touch SDK tools 2.0.0 but could not run it properly. It created an entry in the $PATH variable.

Spring mvc 3 : How to get path variable in an interceptor?

我只是一个虾纸丫 提交于 2019-12-02 22:15:19
In Spring MVC controller, I can get path variable using @PathVariable to get the value of a variable defined in @RequestMapping. How can I get the value of the variable in an interceptor? Thank you very much! The thread linked to by Pao worked a treat for me In the preHandle() method you can extract the various PathVariables by running the following code Map pathVariables = (Map) request.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE); There is a thread in the Spring forums, where someone says, there is no "easy way", so i suppose you would have to parse the URL to get it. Almost

I just installed Maven and added the \bin directory of maven to my path variables. When I try to use the mvn command in the Command Prompt I just get a message: mvn: command not found Everything else I found on here did not help yet. Edit: I used https://maven.apache.org/install.html to install maven. SET PATH=%PATH%;C:\Program Files\Maven\apache-maven-3.5.0\bin\mvn.cmd PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC You have included the file in the path: C:\Program Files\Maven\apache-maven-3.5.0\bin\mvn.cmd That is not good. The PATH environment variable should only include a

Spring MVC: how to indicate whether a path variable is required or not?

瘦欲@ 提交于 2019-11-28 06:44:41
I am doing a Spring web. For a controller method, I am able to use RequestParam to indicate whether a parameter it is required or not. For example: @RequestMapping({"customer"}) public String surveys(HttpServletRequest request, @RequestParam(value="id", required = false) Long id, Map<String, Object> map) I would like to use PathVariable such as the following: @RequestMapping({"customer/{id}"}) public String surveys(HttpServletRequest request, @PathVariable("id") Long id, Map<String, Object> map) How can I indicate whether a path variable is required or not? I need to make it optional because

@PathVariable in SpringBoot with slashes in URL

泄露秘密 提交于 2019-11-28 01:51:14
I have to get params from URL using @PathValiable in SpringBoot application. These params often have slashes . I don't have a control about what a user would enter in URL so I would like to get what he has entered and then I can handle with it. I have already looked through materials and answers here, I don't think that for me the good solution is to ask users somehow encode the entering params. The SpringBoot code is simple: @RequestMapping("/modules/{moduleName}") @ResponseBody public String moduleStrings (@PathVariable("moduleName") String moduleName) throws Exception { ... } So the URL for

Bind Path variables to a custom model object in spring

一个人想着一个人 提交于 2019-11-27 14:35:47
I have a class that models my request, something like class Venue { private String city; private string place; // Respective getters and setters. } And I want to support a RESTful URL to get information about a venue. So I have controller method like this. @RequestMapping(value = "/venue/{city}/{place}", method = "GET") public String getVenueDetails(@PathVariable("city") String city, @PathVariable("place") String place, Model model) { // code } Is there a way, I can say in spring to bind my path variables to the model object (in this case Venue) instead of getting every individual parameter?
