Spring Boot应用程序中多个Angular客户端的RequestMapping问题 [英] RequestMapping issue with multiple Angular clients in Spring Boot Application

问题描述

我需要处理一些GET请求才能转发到多个Angular客户端.

I need to handle some GET requests in order to forward to multiple Angular clients.

https://example.com/web/index.html    // Client 1
https://example.com/admin/index.html  // Client 2

由于我不想为/web使用碎片化的(# -ed)路径，所以事情变得相当糟糕.

Since I don't want to use fragmented (#-ed) paths for /web things get rather annyoing.

这是我当前的不起作用解决方案:

This is my current not working solution:

@Controller
public class ForwardController {

    @RequestMapping(value = "/*", method = RequestMethod.GET)
    public String redirectRoot(HttpServletRequest request) {

        String req = request.getRequestURI();

        if (req.startsWith("/admin/")) {
            return this.redirectAdminTool(request);
        }

        return "forward:/web/index.html";
    }

    @RequestMapping(value = "/web/{path:[^.]*}", method = RequestMethod.GET)
    public String redirectWeb(HttpServletRequest request) {
        return "forward:/web/index.html";
    }

    @RequestMapping(value = "/admin/{path:[^.]*}", method = RequestMethod.GET)
    public String redirectAdminTool(HttpServletRequest request) {
        return "forward:/admin/index.html";
    }
}

有了这个，有效的工作就是访问例如

With this, what does work is accessing e.g.

• /web/pricing

但是无法访问

• /web/pricing/vienna

我可以通过浏览器访问/web/pricing，点击"刷新"，一切正常.但这不适用于/web/pricing/vienna.

I can access /web/pricing via browser, hit "refresh" and everything will work. But it does not for /web/pricing/vienna.

现在，我无法弄清楚如何处理请求以及如何转发请求，以使像/web/pricing/vienna这样的子路径也能正常工作.

Now, I cannot figure out how to handle the requests and how to forward them in order to make sub-paths like /web/pricing/vienna to work as well.

有什么办法可以使这项工作完成?

Is there any way I can make this work?

如果将@RequestMapping路径更改为类似/web/**的内容，则整个过程将陷入无休止的循环并破坏服务器.

If I change the @RequestMapping path to something like /web/** the whole thing ends up in an endless loop and breaks the server.

我可能需要的是这样的表达式:

What I probably need is an expression like this:

/web(/[^\\.]*)

这将导致

MATCH:    /web/pricing
MATCH:    /web/specials/city
MATCH:    /web/specials/city/street
NO MATCH: /web/index.html

但是，Spring不喜欢此正则表达式:/web(/[^\\.]*)

However, Spring does not like this regex: /web(/[^\\.]*)

最后，这个问题归结为找到一种方法来匹配除/web以下的静态资源以外的所有其他事物.

In the end this issue boils down to finding a way to match everythign except static resources below /web.

推荐答案

这就是我最终要做的事情:

Here is what I ended up doing:

我将两个客户端都移到了子目录a/:

I moved both clients to a subdirectory a/:

static/a/web
static/a/admin

此外，我实现了这样的ForwardController:

Further, I implemented a ForwardController like this:

@Controller
public class ForwardController {

    @RequestMapping(value = "/*", method = RequestMethod.GET)
    public String redirectRoot(HttpServletRequest request) {
        return "forward:/a/web/index.html";
    }

    @RequestMapping(value = "/a/**/{path:[^.]*}", method = RequestMethod.GET)
    public String redirectClients(HttpServletRequest request) {

        String requestURI = request.getRequestURI();

        if (requestURI.startsWith("/a/admin/")) {
            return "forward:/a/admin/index.html";
        }

        return "forward:/a/web/index.html";
    }

}
