我在服务器上运行了一个Jersey REST Service应用程序。这个应用程序应该从一个桌面应用程序访问一个集成的浏览器，我可以定义HTML页面与Javascript。因此，客户端代码以原点d：//在本地执行。当我在具有localhost地址的本地计算机上运行Jersey应用程序时，一切都运行得非常好。但是，当我在服务器上部署Jersey应用程序并尝试从桌面应用程序访问它时，返回一个状态为0的错误。在我的本地计算机上使用Postman，我没有问题访问服务器上的球衣应用程序。然而，当我检查我的日志时，我看到，没有通过Postman发送的预检请求（没有原始请求!= null）。
基于这个问题，我猜测，这与CORS有关。我添加了一个CORS过滤器到我的泽西岛应用程序，但它仍然不工作。服务器未注册来自桌面应用程序的任何传入请求。有人知道我错过了什么吗？谢谢你的支持。
我在Desktop应用程序中查询数据的代码：

var ajaxObj = {
        type: "POST", 
        url: jerseyApplicationUrl,
        crossDomain: true,
        data: JSON.stringify(inputFile),  
        contentType:"application/json",
        error: function(jqXHR, textStatus, errorThrown) {
            console.log("Error "+ textStatus +" " + jqXHR.getAllResponseHeaders() + " " + errorThrown+ " "+ jqXHR.status+" " +jqXHR.responseText);
        //Output: Error error 0 undefined
        },
        success: function(data) { 
                console.log("Server returns success for data query with result ");
        },
        complete: function(XMLHttpRequest) {
            //console.log( XMLHttpRequest.getAllResponseHeaders() );
        }, 
        dataType: "json" //request JSON 
    };
    $.ajax(ajaxObj);

我在泽西岛申请的CORS课程：

@Provider
@PreMatching
public class CorsFilter implements ContainerRequestFilter, ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext request) throws IOException {
    // If it's a preflight request, we abort the request with 
    // a 200 status, and the CORS headers are added in the
    // response filter method below.
    if (isPreflightRequest(request)) {
        request.abortWith(Response.ok().build());
        return;
    }
}

/**
 * A preflight request is an OPTIONS request
 * with an Origin header.
 */
private static boolean isPreflightRequest(ContainerRequestContext request) {
    return request.getHeaderString("Origin") != null
            && request.getMethod().equalsIgnoreCase("OPTIONS");
}

/**
 * Method for ContainerResponseFilter.
 */
@Override
public void filter(ContainerRequestContext request, ContainerResponseContext response)
        throws IOException {
    boolean debug = MtcServiceApplication.getInstance()!=null?MtcServiceApplication.getInstance().isDebug():false;
    // if there is no Origin header, then it is not a
    // cross origin request. We don't do anything.
    if (request.getHeaderString("Origin") == null) {
        return;
    }

    // If it is a preflight request, then we add all
    // the CORS headers here.
    if (isPreflightRequest(request)) {
        response.getHeaders().add("Access-Control-Allow-Credentials", "true");
        response.getHeaders().add("Access-Control-Allow-Methods",
            "GET, POST, PUT, DELETE, OPTIONS, HEAD");
        response.getHeaders().add("Access-Control-Allow-Headers",
            // Whatever other non-standard/safe headers (see list above) 
            // you want the client to be able to send to the server,
            // put it in this list. And remove the ones you don't want.
            "X-Requested-With, Authorization, " +
            "Accept-Version, Content-MD5, CSRF-Token, Content-Type");
    }
    
    // Cross origin requests can be either simple requests
    // or preflight request. We need to add this header
    // to both type of requests. Only preflight requests
    // need the previously added headers.
    response.getHeaders().add("Access-Control-Allow-Origin", "*");
}
