JAX-RS Apache Oltu服务器请求带有JSON主体

我正在尝试使用ApacheOltu在我的JAX-RS应用程序中实现OAuth2。我发现：https://github.com/apache/oltu/tree/trunk/oauth-2.0/integration-tests/src/test/java/org/apache/oltu/oauth2/integration/endpoints

@POST
@Consumes("application/x-www-form-urlencoded")
@Produces("application/json")
public Response authorize(@Context HttpServletRequest request) throws OAuthSystemException
{
    OAuthTokenRequest oauthRequest = null;
    OAuthIssuer oauthIssuerImpl = new OAuthIssuerImpl(new MD5Generator());
    try {
        oauthRequest = new OAuthTokenRequest(request);
    } catch (OAuthProblemException e) {
    OAuthResponse res = OAuthASResponse.errorResponse(HttpServletResponse.SC_BAD_REQUEST).error(e)
            .buildJSONMessage();
    return Response.status(res.getResponseStatus()).entity(res.getBody()).build();
}

这适用于application/x-www-form-urlencoded。然而，我也想得到对application/json的支持。我找不到任何关于如何扩展或实现它的文档。有人熟悉这个问题吗？

最好我想重用OAuthTokenRequest
