Description

Hi,

Same problem as CXF-7474, but for JBoss EAP 7.0 & CXF 3.2.4.

The SwaggerUiResolver is not able to find the swagger-ui jar, included in our war via maven; the path returned by the class loader ends with ".jar/" instead of the expected ".jar" or ".jar!/".

To bypass the problem, we modified the checkUiRoot as follow:

// Artifact: cxf-rt-rs-service-description-swagger
// Class: org.apache.cxf.jaxrs.swagger.SwaggerUiResolver
protected static String checkUiRoot(String urlStr, String swaggerUiVersion)
{
  int swaggerUiIndex = urlStr.lastIndexOf("/swagger-ui-");
  if (swaggerUiIndex != -1)
  {
    boolean urlEndsWithJarSep = urlStr.endsWith(".jar!/");
    int offset = -1;

    if (urlEndsWithJarSep || urlStr.endsWith(".jar"))
    {
      offset = urlEndsWithJarSep ? 6 : 4;
    }
    else if (urlStr.endsWith(".jar/"))
    {
      offset = 5;
      urlEndsWithJarSep = true;
    }

    if (offset > -1)
    {
      String version = urlStr.substring(swaggerUiIndex + 12, urlStr.length() - offset);
      if (swaggerUiVersion != null && !swaggerUiVersion.equals(version))
      {
        return null;
      }
      else
      {
        if (!urlEndsWithJarSep)
        {
          urlStr = "jar:" + urlStr + "!/";
        }

        return urlStr + "META-INF/resources/webjars/swagger-ui/" + version + "/";
      }
    }
  }

  return null;
}
