Question

我正在WebSphere 8.5.5.9上部署具有jersey 2.25的Web应用程序。我们正在通过下面的类注册资源。

public class ApplicationResourceConfig extends ResourceConfig {

/**
 * 
 */
public ApplicationResourceConfig() {
    packages(verifyAndLoadResources());
}

/**
 * @return
 */
private String[] getAllResources() {
    List<String> resources = new ArrayList<>();
    resources.add("com.ofs.fsapps.commonapps.appPreferences.resource.AppPreferencesResource");  

    resources.add("com.ofs.fsapps.commonapps.summary.rest.Summary");
    return resources.toArray(new String[0]);
}

/**
 * @return
 */
private String[] verifyAndLoadResources() {
    List<String> packageResourceList = new ArrayList<>();
    for (String resource : getAllResources()) {
        try {
            Class<?> result = Class.forName(resource);
            if (result != null) {
                register(StringUtils.substringAfterLast(resource, ".") + ".class");
                packageResourceList.add(StringUtils.substringBeforeLast(resource, "."));
            }
        } catch (ClassNotFoundException e) {
            System.out.println("Package/Class not Found : "+resource);
        }catch(Exception e) {
            System.out.println("Exception in loading Package/Class : "+resource);
        }
    }
    return packageResourceList.toArray(new String[0]);
}

}

使用上述方法，其余的调用均无法正常工作并以404响应。如果我们在web.xml中输入包/类，则一切正常。

    <servlet>
    <servlet-name>CommonRESTServlet</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>com.ofs.fsapps.commonapps.summary.rest.Summary, com.ofs.fsapps.commonapps.appPreferences.resource.AppPreferencesResource</param-value>
    </init-param>
</servlet>

请注意，已创建共享库，并且该库也与EAR链接。

下面是SystemErr.log中的异常。

带有Jersey 2.25的WebSphere 8.5.5.9
