maven工程增加jetty，weblogic虚拟路径

    项目中需要配置Jetty虚拟目录，来放置一些图片，代码如下：

<plugin>    
    <groupId>org.eclipse.jetty</groupId>    
    <artifactId>jetty-maven-plugin</artifactId>    
    <version>${jetty.version}</version>    
    <configuration>    
        <encoding>UTF-8</encoding>    
        <scanIntervalSeconds>10</scanIntervalSeconds>    
        <contextXml>${project.basedir}/src/test/resources/jetty-context.xml</contextXml>    
        <!-- <jettyXml>${project.basedir}/src/test/resources/jetty.xml</jettyXml> -->    
         <webAppConfig>      
             <defaultsDescriptor>${project.basedir}/src/test/resources/webdefault.xml</defaultsDescriptor>      
        </webAppConfig>        
        <stopKey>foo</stopKey>    
        <stopPort>9999</stopPort>    
        <webApp>    
            <contextPath>/</contextPath>    
        </webApp>    
        <!-- 额外监听目录 -->    
        <contextHandlers>    
            <!-- 附件目录服务 -->    
            <contextHandler implementation="org.eclipse.jetty.webapp.WebAppContext">    
                <contextPath>/upload</contextPath>    
                <resourceBase>/home/baseos/upload/</resourceBase>    
            </contextHandler>    
        </contextHandlers>    
    </configuration>    
    <executions>    
        <execution>    
            <id>start-jetty</id>    
            <phase>pre-integration-test</phase>    
            <goals>    
                <goal>run</goal>    
            </goals>    
            <configuration>    
                <scanIntervalSeconds>0</scanIntervalSeconds>    
                <daemon>true</daemon>    
            </configuration>    
        </execution>    
        <execution>    
            <id>stop-jetty</id>    
            <phase>post-integration-test</phase>    
            <goals>    
                <goal>stop</goal>    
            </goals>    
        </execution>    
    </executions>    
</plugin> 

访问服务/upload时相当于访问/home/baseos/upload/文件路径

weblogic.xml代码参考如下：

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE weblogic-web-app  
  PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN"  
  "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd">
<wls:weblogic-web-app xmlns:wls="http://www.bea.com/ns/weblogic/weblogic-web-app"
    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 http://www.bea.com/ns/weblogic/weblogic-web-app http://www.bea.com/ns/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">
  <wls:virtual-directory-mapping>
       <wls:local-path>/weblogic/</wls:local-path>
       <wls:url-pattern>/myimages/*</wls:url-pattern>
  </wls:virtual-directory-mapping>
</wls:weblogic-web-app>

 访问服务/myimages时相当于访问/weblogic/myimages文件路径
