maven創建web項目，並用jetty調試

  1、mvn archetype:create -DgroupId=org.david.app -DartifactId=mywebapp -DarchetypeArtifactId=maven-archetype-webapp 
2、cd mywebapp 
     mvn eclipse:eclipse 
     導入eclipse工程 
     （或者直接從eclipse中導入maven工程） 
3、添加servlet依賴 
        <dependency> 
      <groupId>javax.servlet</groupId> 
      <artifactId>servlet-api</artifactId> 
      <version>2.5</version> 
    </dependency> 
4、添加源代碼目錄src/main/java 
     將源代碼放在該目錄下。 
5、添加jetty插件 
<build> 
   <finalName>mywebapp</finalName> 
   <plugins> 
        <plugin> 
          <groupId>org.apache.maven.plugins</groupId> 
          <artifactId>maven-compiler-plugin</artifactId> 
          <configuration> 
            <source>1.5</source> 
            <target>1.5</target> 
          </configuration> 
        </plugin> 
        <plugin> 
          <groupId>org.mortbay.jetty</groupId> 
          <artifactId>maven-jetty-plugin</artifactId> 
        </plugin>       
   </plugins> 
</build> 
6、用jetty調試（http://www.blogjava.net/alwayscy/archive/2007/06/01/118584.html） 
命令行：mvn jetty:run
