无法找到运行在SpringBoot上的WebSphere应用程序的webjars

Question

我一直试图在WebSphere服务器上托管Spring应用程序。

版本：

• SpringBoot 2.1.6 SpringBoot
• 自由WebSphere 19.0.0.6与JavaEE 8
• webjars-定位器0.36

该应用程序成功地部署在独立的Tomcat 9.0.22上，可以在那里解析webjars。然而，对于WebSphere，当试图从html页面访问webjars时，我会收到一个错误：

2019-08-05 10:43:11.839 DEBUG 1 --- [ecutor-thread-6] o.s.web.servlet.DispatcherServlet        : GET "/appcontext/webjars/jquery/jquery.min.js", parameters={}
2019-08-05 10:43:11.845 DEBUG 1 --- [ecutor-thread-6] o.s.w.s.handler.SimpleUrlHandlerMapping  : Mapped to ResourceHttpRequestHandler ["classpath:/META-INF/resources/webjars/"]
2019-08-05 10:43:11.849 DEBUG 1 --- [ecutor-thread-6] o.s.w.s.r.ResourceHttpRequestHandler     : Resource not found
2019-08-05 10:43:11.849 DEBUG 1 --- [ecutor-thread-6] o.s.web.servlet.DispatcherServlet        : Completed 404 NOT_FOUND

Spring成功地映射了webjars模式：

2019-08-05 10:43:09.039 DEBUG 1 --- [ecutor-thread-6] o.s.w.s.handler.SimpleUrlHandlerMapping  : Patterns [/webjars/**, /**] in 'resourceHandlerMapping'

Answer 1

解决方案是将classloading条目(将useJarUrls属性设置为true )添加到WebSphere server.xml文件中：

<server description="myServer">
    <featureManager>
        <feature>servlet-3.0</feature>
    </featureManager>
    <classloading useJarUrls="true"/> <!-- this line was added -->
    <httpEndpoint httpPort="9080" httpsPort="9443" host="*" id="defaultHttpEndpoint"/>
</server>

这个IBM support issue特别有助于解决这个问题。
