Spring 3.0 多个@PathVariable的问题

发布于 2024-11-29 05:47:31 字数 729 浏览 0 评论 0原文

在我的应用程序中，我必须比较控制器中的 3 个产品，

@RequestMapping(value = "/products/{proId1}Vs{proId2}Vs{proId3}", method = RequestMethod.GET)
public ModelAndView compareThreeProducts(@PathVariable("proId1") int id1, @PathVariable("proId2") int id2, @PathVariable("proId3") int id3)
{
   //someLogic

当点击我的 url(http://something/products/12Vs13Vs14) 时，

我映射了请求，我收到 http 400 错误，

我也尝试了 2 个 @pathVariable，如下

@RequestMapping(value = "/products/{proId1}Vs{proId2}", method = RequestMethod.GET)
public ModelAndView compareTwoProducts(@PathVariable("proId1") int id1, @PathVariable("proId2") int id2)

所示工作正常，但为什么我面临 3 个变量的问题，而且服务器日志中也没有错误，那么如何找到错误所在。

有什么解决办法吗？？

In my application I have to compare 3 products for that in my controller I mapped request as

@RequestMapping(value = "/products/{proId1}Vs{proId2}Vs{proId3}", method = RequestMethod.GET)
public ModelAndView compareThreeProducts(@PathVariable("proId1") int id1, @PathVariable("proId2") int id2, @PathVariable("proId3") int id3)
{
   //someLogic

when hit my url(http://something/products/12Vs13Vs14)

I'm getting http 400 error

I also tried for 2 @pathVariable like

@RequestMapping(value = "/products/{proId1}Vs{proId2}", method = RequestMethod.GET)
public ModelAndView compareTwoProducts(@PathVariable("proId1") int id1, @PathVariable("proId2") int id2)

this is working fine but why i'm facing problem with 3 variables and also there are no errors in server log then how to find what's the bug.

any solution??

如何显式指定您希望每个路径变量匹配的正则表达式，如所述这里？

@RequestMapping(value = "/products/{proId1:\d+}Vs{proId2:\d+}Vs{proId3:\d+}", method = RequestMethod.GET)

您可以尝试将所有内容集中到一个路径变量中，然后手动解析它：

@RequestMapping(value = "/products/{compareIdString}", method = RequestMethod.GET)
public ModelAndView compareThreeProducts(@PathVariable("compareIdString") String compareIdString)
{
    // split compareIdString on "Vs"
    // parse each resulting value to an int

不过，这更多的是一种解决方法，而不是解决方案。如果您想尝试找出到底出了什么问题，您可能需要按照 Bozho 的建议在 Spring 代码中进行调试。

You could try lumping everything into one path variable then parsing it manually:

@RequestMapping(value = "/products/{compareIdString}", method = RequestMethod.GET)
public ModelAndView compareThreeProducts(@PathVariable("compareIdString") String compareIdString)
{
    // split compareIdString on "Vs"
    // parse each resulting value to an int

This is more of a workaround than a solution, though. You might want to debug in the Spring code as Bozho suggested if you want to try to figure out exactly what's going wrong.
