rest - 如何修复 Jersey POST 请求参数警告？

Question

我正在使用 Jersey 构建一个非常简单的 REST API，我的日志文件中有一个我不确定的警告。

WARNING: A servlet POST request, to the URI http://myserver/mycontext/myapi/users/12345?action=delete, contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected.

我的 webapp 只定义了 Jersey servlet，映射到/myapi/*

我怎样才能停止这些警告？

对我来说，警告是针对 POST application/x-www-form-urlencoded 显示的。我正在使用 Spring Boot，它有一个 HiddenHttpMethodFilter，它在其他任何事情之前先执行 getParameter ......所以我最终做了这个讨厌的覆盖:

@Bean
    public HiddenHttpMethodFilter hiddenHttpMethodFilter() {
        return new HiddenHttpMethodFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
                    FilterChain filterChain) throws ServletException, IOException {
                if ("POST".equals(request.getMethod())
                        && request.getContentType().equals(MediaType.APPLICATION_FORM_URLENCODED_VALUE)) {
                    filterChain.doFilter(request, response);
                } else {
                    super.doFilterInternal(request, response, filterChain);
                }
            }
        };
    }
