Jetty9内嵌开发Web项目
1、准备环境
- 下载Jetty：采用Maven方式
注意：apache-jsp用于jsp访问，否则会报错访问jsp页面会报错：jsp support not configured
- 其他依赖
spring4.x
jdk1.8
2、编写Jetty web项目启动类
package com.onion.web.servlet.jetty;
import java.io.File;
import java.net.URL;
import java.security.ProtectionDomain;
import java.util.Arrays;
import org.apache.tomcat.InstanceManager;
import org.apache.tomcat.SimpleInstanceManager;
import org.eclipse.jetty.apache.jsp.JettyJasperInitializer;
import org.eclipse.jetty.plus.annotation.ContainerInitializer;
import org.eclipse.jetty.server.Connector;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.ServerConnector;
import org.eclipse.jetty.webapp.WebAppContext;
import com.onion.common.config.OnionConfig;
/**
* Jetty Web应用启动器
* @author aton
* @since 2017-09-21
*/
public class JettyLauncher {
private static final int PORT = OnionConfig.getInteger("web.port", 8080);//web项目端口
private static final String APP_ROOT_PATH = "src/test/webapp";//web项目本地路径
private static final String CONTEXT_PATH = "/onion";//上下文
public static void runJettyServer(int port, String contextPath) {
Server server = createDevServer(port, contextPath);
try {
server.start();
server.join();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
server.stop();
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static Server createDevServer(int port, String contextPath) {
Server server = new Server();
server.setStopAtShutdown(true);
ServerConnector connector = new ServerConnector(server);
// 设置服务端口
connector.setPort(port);
connector.setReuseAddress(false);
server.setConnectors(new Connector[] {connector});
// 设置web资源根路径以及访问web的根路径
WebAppContext webRoot = new WebAppContext(APP_ROOT_PATH, contextPath);
webRoot.setDescriptor(APP_ROOT_PATH + "/WEB-INF/web.xml");
webRoot.setResourceBase(APP_ROOT_PATH);
webRoot.setDisplayName("shiro");
webRoot.setClassLoader(Thread.currentThread().getContextClassLoader());
webRoot.setConfigurationDiscovered(true);
webRoot.setParentLoaderPriority(true);
//JSP相关，由于jetty升级原因，在9.4.x版本一定要增加以下代码，否则会出现错误1；
File temp = new File(APP_ROOT_PATH + "/temp");
webRoot.setTempDirectory(temp);
webRoot.setAttribute("javax.servlet.context.tempdir", temp);
webRoot.setAttribute("org.eclipse.jetty.containerInitializers" , Arrays.asList (
new ContainerInitializer(new JettyJasperInitializer(), null)));
webRoot.setAttribute(InstanceManager.class.getName(), new SimpleInstanceManager());
server.setHandler(webRoot);
return server;
}
/********************************************************************/
public static void main(String[] args) {
runJettyServer(PORT, CONTEXT_PATH);
}
}
2、Web.xml
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
3、错误1
