Maven 教程3-怎样启动web项目

方案1：dos运行

运行cmd输入

• mvn jetty:run

jetty插件版本

• 先在pom.xml添加jetty插件
• jdk7可以使用jetty插件7.1.0.RC1
• jdk8要使用高版本插件，如8.1.16.v20140903

<plugin>
                <groupId>org.mortbay.jetty</groupId>
                <artifactId>jetty-maven-plugin</artifactId>
                <!--jdk1.7-->
                <!--version>7.1.0.RC1</version-->
                <!--jdk1.8-->
                <version>8.1.16.v20140903</version>
                <configuration>
                    <webAppConfig>
                        <contextPath>/</contextPath>
                    </webAppConfig>
                </configuration>
            </plugin>

方案2：Eclipse运行

安装tomcat插件

下载地址http://www.eclipsetotale.com/tomcatPlugin.html
- tomcatPluginV331.zip
http://www.eclipsetotale.com/tomcatPlugin/tomcatPluginV331.zip
- 解压缩之后，只有一个jar文件
把此jar文件放入eclipse根目录plugin

配置运行

• 打勾
  添加tomcat插件,打一个唯一的勾后运行tomcat，相当于把pom里面配置的jar文件和编译的class添加到tomcat的classpath
  
• 添加server runtime至工程
• 修改外置tomcat的server.xml

<Context path="" docBase="指向webapp文件路径"/>

方案3：右键运行

pom.xml配置一下把maven项目变成标准web工程结构
