Vadim Beilin commented on CXF-7474:
-----------------------------------
In our case URLClassLoader.getURLs() contains only the URL of
all_dependencies.jar, and all_dependencies.jar!/META-INF/MANIFEST.MF has
swagger-ui-NNN.jar in its Class-Path attribute. So iteration over the
URLClassLoader's classpath reveals all_dependencies.jar, but not the swagger-ui
jar.
This is my test (I modified findSwaggerUiRoot to accept ClassLoader for testing
purposes):
{code}
File tmpfile = Files.createTempFile("all_dependencies",
".jar").toFile();
tmpfile.deleteOnExit();
Manifest mf = new Manifest();
mf.getMainAttributes().put(Attributes.Name.MANIFEST_VERSION, "1.0");
mf.getMainAttributes().put(Attributes.Name.CLASS_PATH,
"......./swagger-ui-2.1.2.jar"); // <- location of the
swagger-ui jar, differrent form the default version
JarOutputStream jos = new JarOutputStream(new
FileOutputStream(tmpfile), mf);
jos.flush();
jos.close();
try (URLClassLoader cl = new URLClassLoader(new URL[] {
tmpfile.toURI().toURL() }, null);) {
String uiroot = SwaggerUiResolver.findSwaggerUiRoot(cl, null,
null); // <-- modification for testing purposes
Assert.assertNotNull("not found in all_dependencies.jar", uiroot);
Assert.assertThat(uiroot, containsString("2.1.2"));
}
{code}
> Swagger2Feature - Swagger UI not working with JBoss
> ---------------------------------------------------

> Key: CXF-7474
> URL: https://issues.apache.org/jira/browse/CXF-7474
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.2.0
> Reporter: Olivier Paquet
> Assignee: Sergey Beryozkin
> Fix For: 3.1.13, 3.2.0
>
>
> Hi,
> We currently try to use the Swagger2Feature with the Swagger UI integration,
> so following your documentation. So we added the dependency in our Maven
> project.
> {code}
> Enabling Swagger UI
> First one needs to add the following
> <dependency>
> <groupId>org.webjars</groupId>
> <artifactId>swagger-ui</artifactId>
> <version>2.2.10-1</version>
> </dependency>
> The newest version 3.x of swagger-ui can also be used.
> {code}
> But after deploying the application in a JBoss 6.4 EAP, the url containing
> the /api-docs could not be mapped.
> So I debugged the
> https://github.com/apache/cxf/blob/master/rt/rs/description-swagger/src/main/java/org/apache/cxf/jaxrs/swagger/SwaggerUiResolver.java
> and found out that you do something like:
> {code}
> final String resourcesRootStart = "META-INF/resources/webjars/swagger-ui/";
> ClassLoader cl = AbstractSwaggerFeature.class.getClassLoader();
> if (cl instanceof URLClassLoader) { ...
> {code}
> But in JBoss the Classloader is of type ModuleClassloader, so it will never
> get into this if case.
> So I added the following code to bypass this issue :
> {code}
> } else {
> Enumeration<URL> urls =
> cl.getResources("META-INF/resources/webjars/swagger-ui/");
> while (urls.hasMoreElements()) {
> URL url = urls.nextElement();
> String urlStr = url.toString();
> urlStr =
> urlStr.replace("META-INF/resources/webjars/swagger-ui/", "");
> int swaggerUiIndex = urlStr.lastIndexOf("/swagger-ui-");
> if (swaggerUiIndex != -1) {
> boolean urlEndsWithJarSep = urlStr.endsWith(".jar!/");
> if (urlEndsWithJarSep || urlStr.endsWith(".jar")) {
> int offset = urlEndsWithJarSep ? 6 : 4;
> String version = urlStr.substring(swaggerUiIndex +
> 12, urlStr.length() - offset);
> if (swaggerUiVersion != null &&
> !swaggerUiVersion.equals(version)) {
> continue;
> }
> if (!urlEndsWithJarSep) {
> urlStr = "jar:" + urlStr + "!/";
> }
> return urlStr + resourcesRootStart + version + "/";
> }
> }
> }
> }
> {code}
> This was not working directly because of the JBoss VFS filesystem, so I moved
> the swagger-ui.jar into a separater JBoss module which I included using a
> jboss-deploymentstructure.xml.
> Now the url
> http://localhost:8081/.../app/swaggerSample/api-docs?url=http://localhost:8081/.../app/swaggerSample/swagger.json
> is working and displays me the Swagger UI.
> Here are the information:
> - CXF version: 3.2.0-SNAPSHOT
> - Java 8
> - JBoss 6.4 EAP / JBoss Wildfly 10
> I can provide you with all information in case you need my project / war file
> ...
