Jetty 嵌入式开发（实例）

qianqianling

　　我尝试了jetty几个版本，类的使用有些差异，在此记录下jettyVersion = 9.0.2.v20130417 的部分实例
　　maven 依赖及配置：



<properties>
<!-- Adapt this to a version found on http://central.maven.org/maven2/org/eclipse/jetty/jetty-maven-plugin/ -->
<jettyVersion>9.0.2.v20130417</jettyVersion>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<!-- jetty 依赖 -->
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>${jettyVersion}</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
<configuration>
<mainClass>org.example.HelloWorld</mainClass>
</configuration>
</plugin>
</plugins>
</build>
　　以下是示例代码：



package com.bocom.testjetty.httpserver;
import org.eclipse.jetty.server.Connector;
import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.ServerConnector;
import org.eclipse.jetty.server.handler.ContextHandler;
import org.eclipse.jetty.server.handler.HandlerList;
public class httpserver {
public static void main(String[] arg0) throws Exception{
server1();
server2();
}
/**
* 多个连接器实例
* @throws Exception
*/
public static void server1() throws Exception{
Server server = new Server();
ServerConnector connector1 = new ServerConnector(server);
connector1.setPort(8082);
ServerConnector connector2 = new ServerConnector(server);
connector2.setPort(9001);
server.setConnectors(new Connector[] { connector1, connector2 });
server.setHandler(new HelloHandler());
server.start();
}
/**
* 多个handler实例
* @throws Exception
*/
public static void server2() throws Exception {
Server server = new Server(9080);
ContextHandler context1 = new ContextHandler();
context1.setContextPath("/hello");
context1.setHandler(new HelloHandler());
ContextHandler context2 = new ContextHandler();
context2.setContextPath("/content");
context2.setHandler(new HelloHandler());
HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[]{context1,context2});
server.setHandler(handlers);
server.start();
server.join();
}

}
package com.bocom.testjetty.httpserver;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.server.handler.AbstractHandler;
public class HelloHandler extends AbstractHandler{
public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html;charset=utf-8");
response.setStatus(HttpServletResponse.SC_OK);//响应状态码
baseRequest.setHandled(true);
response.getWriter().println("<a>你好！</a>");
}
}
