问如何在rest中检查传入的请求URL

EN

@RequestMapping(value = { "/", " * " })
public ResponseEntity<?> redirectRequest(HttpServletRequest httpServletRequest) {
        String bodyRequest = "";
    String baseURL = "";
    if ("POST".equalsIgnoreCase(httpServletRequest.getMethod())
            || "PUT".equalsIgnoreCase(httpServletRequest.getMethod())) {
        try {
            bodyRequest = httpServletRequest.getReader().lines()
                    .collect(Collectors.joining(System.lineSeparator()));
        } catch (IOException e) {

        }
    }

    HttpEntity<?> request = new HttpEntity<>(bodyRequest);
    Enumeration<String> headerNames = httpServletRequest.getHeaderNames();

    if (headerNames != null) {
        while (headerNames.hasMoreElements()) {
            String headerName = headerNames.nextElement();
            request.getHeaders().add(headerName, httpServletRequest.getHeader(headerName));
        }
    }

    if (httpServletRequest.getContextPath().contains("api/lb1"))
        baseURL = "lb ur1";
    else
        baseURL = "lb url 2";
    return restTemplate.exchange(baseURL + httpServletRequest.getContextPath(),
            HttpMethod.resolve(httpServletRequest.getMethod()), request, ResponseEntity.class,
            httpServletRequest.getRequestURI());

}
