maven集成jetty插件热部署

一、org.eclipse.jetty插件启动

1.maven依赖

<dependency>
   <groupId>org.eclipse.jetty</groupId>
   <artifactId>jetty-webapp</artifactId>
   <version>9.4.5.v20170502</version>
</dependency>

2.plugin

<plugin>
 <groupId>org.eclipse.jetty</groupId>
 <artifactId>jetty-maven-plugin</artifactId>
 <version>9.4.5.v20170502</version>
 <configuration>
 <httpConnector>
   <port>8080</port>
 </httpConnector>
 <stopKey>shutdown</stopKey>
   <stopPort>9966</stopPort>
   <scanIntervalSeconds>3</scanIntervalSeconds>
   <webApp>
    <contextPath>/ciyo</contextPath>
    <descriptor>src/main/webapp/WEB-INF/web.xml</descriptor>
    <resourceBases>
     <resourceBase>${project.basedir}/src/main/webapp</resourceBase>
    </resourceBases>
   </webApp>
   <requestLog implementation="org.eclipse.jetty.server.NCSARequestLog">
     <filename>target/access-yyyy_mm_dd.log</filename>
     <filenameDateFormat>yyyy_MM_dd</filenameDateFormat>
     <logDateFormat>yyyy-MM-dd HH:mm:ss</logDateFormat>
     <logTimeZone>GMT+8:00</logTimeZone>
     <append>true</append>
     <logServer>true</logServer>
     <retainDays>120</retainDays>
     <logCookies>true</logCookies>
     </requestLog>
  </configuration>
</plugin>

二、Java Main 函数启动

1.maven依赖

<dependency>
   <groupId>org.eclipse.jetty</groupId>
   <artifactId>jetty-webapp</artifactId>
   <version>9.4.5.v20170502</version>
</dependency>
<dependency>
   <groupId>org.eclipse.jetty</groupId>
   <artifactId>jetty-jsp</artifactId>
   <version>9.2.22.v20170606</version>
</dependency>

2.server_config.properties

server.host=0.0.0.0
server.web.port=8080
server.web.warFile=src/main/webapp
server.web.contextPath=/ciyo
