VAADIN：未从文件系统或类加载器中找到 MyAppWidgetset.nocache.js

  • 772

大家好！将 Web 应用程序部署到 tomcat 服务器。通过intellij idea这里具有这样的特点：

<component name="ArtifactManager">
  <artifact type="exploded-war" build-on-make="true" name="webrp:war exploded">
    <output-path>$PROJECT_DIR$/target/webrp-1.0</output-path>
    <root id="root">
      <element id="directory" name="WEB-INF">
        <element id="directory" name="classes">
          <element id="module-output" name="webrp" />
        </element>
        <element id="directory" name="lib">
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-server:7.6.7" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-sass-compiler:0.9.13" />
          <element id="library" level="project" name="Maven: com.vaadin.external.flute:flute:1.3.0.gg2" />
          <element id="library" level="project" name="Maven: com.yahoo.platform.yui:yuicompressor:2.4.8" />
          <element id="library" level="project" name="Maven: rhino:js:1.7R2" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-shared:7.6.7" />
          <element id="library" level="project" name="Maven: com.vaadin.external.streamhtmlparser:streamhtmlparser-jsilver:0.0.10.vaadin1" />
          <element id="library" level="project" name="Maven: com.vaadin.external.google:guava:16.0.1.vaadin1" />
          <element id="library" level="project" name="Maven: org.jsoup:jsoup:1.8.3" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-push:7.6.7" />
          <element id="library" level="project" name="Maven: com.vaadin.external.atmosphere:atmosphere-runtime:2.2.7.vaadin1" />
          <element id="library" level="project" name="Maven: com.vaadin.external.slf4j:vaadin-slf4j-jdk14:1.6.1" />
          <element id="library" level="project" name="Maven: org.w3c.css:sac:1.3" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-themes:7.6.7" />
          <element id="library" level="project" name="Maven: org.tltv.gantt:gantt-addon:0.9.3" />
        </element>
      </element>
      <element id="javaee-facet-resources" facet="webrp/web/Web" />
    </root>
  </artifact>
</component>

结果，我有一个错误：

Aug 09, 2016 9:51:40 AM com.vaadin.server.VaadinServlet serveStaticResourcesInVAADIN
INFO: Requested resource [/VAADIN/widgetsets/ru.comp.webgrp.MyAppWidgetset/ru.comp.webgrp.MyAppWidgetset.nocache.js] not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.

网上介绍的那些方法都不管用，有的也不适合。据我了解，问题是 vaadin 本身不编译。添加更多时出现相同的错误gwt-compiler-output

如果我们添加整个输出：

    <component name="ArtifactManager">
  <artifact type="exploded-war" build-on-make="true" name="webrp:war exploded">
    <output-path>$PROJECT_DIR$/target/webrp-1.0</output-path>
    <root id="root">
      <element id="directory" name="WEB-INF">
        <element id="directory" name="classes">

        </element>
        <element id="directory" name="lib">
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-server:7.6.7" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-sass-compiler:0.9.13" />
          <element id="library" level="project" name="Maven: com.vaadin.external.flute:flute:1.3.0.gg2" />
          <element id="library" level="project" name="Maven: com.yahoo.platform.yui:yuicompressor:2.4.8" />
          <element id="library" level="project" name="Maven: rhino:js:1.7R2" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-shared:7.6.7" />
          <element id="library" level="project" name="Maven: com.vaadin.external.streamhtmlparser:streamhtmlparser-jsilver:0.0.10.vaadin1" />
          <element id="library" level="project" name="Maven: com.vaadin.external.google:guava:16.0.1.vaadin1" />
          <element id="library" level="project" name="Maven: org.jsoup:jsoup:1.8.3" />
          <element id="library" level="project" name="Maven: com.vaadin:vaadin-push:7.6.7" />
          <element id="library" level="project" name="Maven: com.vaadin.external.atmosphere:atmosphere-runtime:2.2.7.vaadin1" />

.........................................

          <element id="library" level="project" name="Maven: org.codehaus.jackson:jackson-xc:1.9.12" />
        </element>
      </element>
      <element id="javaee-facet-resources" facet="webrp/web/Web" />
      <element id="directory" name="VAADIN">
        <element id="directory" name="widgetsets">
          <element id="gwt-compiler-output" facet="webrp/gwt/GWT" />
        </element>
      </element>
    </root>
  </artifact>
</component>

然后我得到一个错误：

这是 WebrUI 的样子：

@Widgetset("ru.comp.webgrp.MyAppWidgetset")
@Title(value = "Планирование")
public class WebrpUI extends UI {

    private Navigator navigator;

    @Override
    protected void init(VaadinRequest request) {
        navigator = new Navigator(this, this);
        navigator.addView("", ResourcesView.class);
        navigator.addView("resources", ResourcesView.class);
    }

    @WebServlet(urlPatterns = "/*", name = "WebrpUIServlet", asyncSupported = true)
    @VaadinServletConfiguration(ui = WebrpUI.class, productionMode = false)
    public static class WebrpUIServlet extends VaadinServlet {
    }
}
