Spring MVC如何设置请求头和响应头的Header

@RequestMapping("/example")
public String handleRequest(@RequestHeader(name = "X-Custom-Header", required = false) String customHeaderValue) {
    // 使用customHeaderValue...
    return "viewName";
}

@ControllerAdvice
public class GlobalHeaderControllerAdvice {
    @AfterResponseBodyAdvice
    public void addGlobalHeader(@RequestHeader HttpHeaders headers) {
        headers.set("X-Global-Response-Header", "GlobalValue");
    }
}

@RequestMapping(value = "/example", method = RequestMethod.GET, headers = "X-Custom-Header=someValue")
public String conditionalRequestMapping() {
    // 方法实现...
}

@RequestMapping("/example")
public String handleRequest(HttpServletRequest request) {
    String customValue = request.getHeader("X-Custom-Header");
    // 使用customValue...
    return "viewName";
}

public class CustomRequestHeaderInterceptor implements ClientHttpRequestInterceptor {
    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
        request.getHeaders().set("X-Custom-Request-Header", "DynamicValue");
        return execution.execute(request, body);
    }
}

public class CustomRequestHeaderFilter implements Filter {
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        httpRequest.setAttribute("X-Custom-Header", "HeaderValue");
        chain.doFilter(request, response);
    }
}

HttpHeaders headers = new HttpHeaders();
headers.set("X-Custom-Request-Header", dynamicHeaderValue);
HttpEntity<String> entity = new HttpEntity<>("Request Body", headers);
restTemplate.exchange(...);

@Controller
@ResponseHeader("X-Custom-Response-Header: DynamicValue")
public class ExampleController {
    // 控制器方法...
}

@RequestMapping("/example")
public String handleRequest(HttpServletResponse response) {
    response.setHeader("X-Custom-Response-Header", "DynamicValue");
    return "viewName";
}

    HttpHeaders headers = new HttpHeaders();
    headers.set("X-Custom-Response-Header", "DynamicValue");
    return new ResponseEntity<>("Response Body", headers, HttpStatus.OK);
}

public class CustomResponseHeaderInterceptor implements HandlerInterceptor {
    @Override

        HttpServletResponse response = (HttpServletResponse) servletResponse;
        response.setHeader("X-Custom-Response-Header", "DynamicValue");
    }
}

public Mono<ResponseEntity<String>> callExternalService(Data data) {
    return webClient.post()
                    .uri("/example")
                    .header("X-Custom-Response-Header", dynamicHeaderValue)
                    .retrieve()
                    .bodyToMono(String.class);
