Question

如何在 Spring @RestController 中注入(inject)完整的子路径？

在我的示例中，我希望注入(inject) subpaths=/test/sub/path

@RestController
public class MyController {
    @GetMapping(value = "/v1/{subpaths}", produces = MediaType.APPLICATION_JSON)
    public Object handle(@PathVariable String subpaths) {
        //this is not called for /v1/test/sub/path
    }
}

实际上，如果想法是有一个单一的入口点，我们可以捕获所有内容，然后提取子路径。 以下说明了相同的内容:

@RestController
public class MyController {
    @GetMapping(value = "/v1/parentPath/**", produces = MediaType.APPLICATION_JSON)
    public Object handle(@RequestParam(name = "myParam") String myParam,HttpServletRequest request) {
        //Get the complete url
        String url=request.getRequestURL();
        String[] paths=url.split("parentPath/");
        //paths[1] is the desired subPath
 
        //Provides URI
        // example : /context-path/v1/parentPath/subPath
        String uri=request.getRequestURI();

        //Returns query string, ex: test=abc&page=1
        String queryString=request.getQueryString();

        //Returns query parameters as map,Includes both query and ported form data
        Map<String, String[]> parameterMap=request.getParameterMap();

    }
}

HttpServletRequest:由Spring自动注入(inject)。(将尝试找到一些文档并将其添加到此处)

为了安全起见，添加了parentPath，以确保我们不会捕获v1下的所有请求
