使用从web.xml配置的defaultservlet,使用jetty 7提供静态内容

Question

这是jetty 7和xml配置,而不是嵌入式.

我正在尝试将一个静态文件crossdomain.xml提供给连接到我从jetty运行的数据源的应用程序.为此,我配置了一个servlet及其映射:

<servlet>
    <servlet-name>default    </servlet-name>
    <servlet-class>org.eclipse.jetty.servlet.DefaultServlet    </servlet-class>
    <init-param>
        <param-name>resourceBase    </param-name>
        <param-value>/foo/foo    </param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>default    </servlet-name>
    <url-pattern>/*    </url-pattern>
</servlet-mapping>

可悲的是,我得到的只是404.任何帮助将不胜感激,顺便说一下我的web.xm lfile的其余部分如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"version="2.5">

<servlet>
    <servlet-name>cometd    </servlet-name>
    <servlet-class>org.cometd.server.continuation.ContinuationCometdServlet    </servlet-class>
    <load-on-startup>1    </load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>cometd    </servlet-name>
    <url-pattern>/cometd/*    </url-pattern>
</servlet-mapping>

<servlet>
    <servlet-name>default    </servlet-name>
    <servlet-class>org.eclipse.jetty.servlet.DefaultServlet    </servlet-class>
    <init-param>
        <param-name>resourceBase    </param-name>
        <param-value>/foo/foo    </param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>default    </servlet-name>
    <url-pattern>/*    </url-pattern>
</servlet-mapping>


<servlet>
    <servlet-name>initializer    </servlet-name>
    <servlet-class>com.foo.research.Initializer    </servlet-class>
    <load-on-startup>2    </load-on-startup>
</servlet>

<filter>
    <filter-name>cross-origin    </filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter    </filter-class>
</filter>
<filter-mapping>
    <filter-name>cross-origin    </filter-name>
    <url-pattern>/cometd/*    </url-pattern>
</filter-mapping>

</web-app>

Answer 1

我遇到过同样的问题; 这是一个有效的片段(Jetty 6.1.22).我基本上用org.mortbay替换了org.eclipse并删除了resourceBase参数(但见下文).这实际上最终出现在我的WAR文件中的web.xml文件中:

  <servlet>
    <servlet-name>myservlet</servlet-name>
    <servlet-class>foo.bar.MyServlet</servlet-class>
    <display-name></display-name>
    <description>The smallest Servlet ever!</description>
  </servlet>
  <servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.mortbay.jetty.servlet.DefaultServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>myservlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/static/*</url-pattern>
  </servlet-mapping>

然后,您必须将静态文件放在WAR文件的"static"目录中.像这样(只是为了说清楚):

  ROOT.war
  |_ WEB-INF/
  |_ static/

如果要将静态文件放在其他位置(但仍将它们映射到/ static/URI下),可以使用resourceBase参数指定目录,就像您一样.

Jetty的文档帮助我更好地理解了这一点:http: //docs.codehaus.org/display/JETTY/Servlets+Bundled+with+Jetty
