问题：我无法获取 */* 在要Map到的客户端消息中 application/json 在服务器端，通过更改服务器代码而不是客户端代码(部署的客户端太多，无法执行后者）
在wildfly 10上，一切都按原样工作（使用 */* )，但在wildfly 14/18上它失败了

RESTEASY002010: Failed to execute: javax.ws.rs.NotSupportedException: RESTEASY003200: Could not find message body reader for type: class xxxx of content type: */* at org.jboss.resteasy.resteasy-
jaxrs@3.9.1.Final//org.jboss.resteasy.core.interception.ServerReaderInterceptorContext.throwReaderNotFound

以上都是在Java8上实现的。下面的代码显示了客户端更改，该更改将使wf14+在没有服务器端编辑的情况下工作：

HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "*/*");  // works for WF10, not WF14+
// conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8"); // works for all

适用的服务器端代码如下：

@POST
@Path("fileDownload")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_OCTET_STREAM)
// Consume options tried that still failed:
// @Consumes({ MediaType.APPLICATION_JSON, MediaType.WILDCARD, MediaType.APPLICATION_OCTET_STREAM, "*/*", "*/*\r\n", "*/*; charset=UTF-8" } )
public Response fileDownload(@HeaderParam("Range") String range, FileDownloadRequest fileDwnReq) throws IOException { ... }

我的网络搜索都指向客户端的变化（这将工作），但我们必须改变服务器端或留在wf10。我也尝试过在web.xml中设置字符集行为或Map媒体类型，但没有什么不同。例如：

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>MyRestServices</display-name>
    <listener>
    <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
    </listener-class>
    </listener>

    <!--   
    To specify the previous behavior, in which UTF-8 was used for text media types, but 
    the explicit charset was not appended, the context parameter "resteasy.add.charset" may be 
    set to "false". It defaults to "true". 
    See https://docs.jboss.org/resteasy/docs/3.1.2.Final/userguide/html_single/index.html
    This did not work.
     -->
<!--     <context-param> -->
<!--        <param-name>resteasy.add.charset</param-name> -->
<!--        <param-value>false</param-value> -->
<!--     </context-param> -->

     <context-param>
        <param-name>resteasy.media.type.mappings</param-name>
        <param-value>*/* : application/json</param-value>
<!-- <param-value>html : text/html, json : application/json, xml : application/xml</param-value> -->
    </context-param>

我被难住了。如有任何建议/建议，将不胜感激。
