我曾尝试运行CAS webapp，例如可执行WAR，最初我发现了两种可能的解决方案。但是会有更好的解决方案吗？
1）创建一个主类来启动Jetty嵌入式服务器并运行CAS war文件;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.apache.tomcat.InstanceManager;
import org.apache.tomcat.SimpleInstanceManager;
import org.eclipse.jetty.annotations.ServletContainerInitializersStarter;
import org.eclipse.jetty.apache.jsp.JettyJasperInitializer;
import org.eclipse.jetty.plus.annotation.ContainerInitializer;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;
import org.h2.jdbcx.JdbcDataSource;
public class CasServerEmbedded {
public static void main(String[] args) throws Exception {
// Create the server
Server server = new Server(8080);
// Enable parsing of jndi-related parts of web.xml and jetty-env.xml
org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList
.setServerDefault(server);
classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration",
"org.eclipse.jetty.plus.webapp.EnvConfiguration", "org.eclipse.jetty.plus.webapp.PlusConfiguration");
// Create a WebApp
final WebAppContext webAppContext = new WebAppContext();
webAppContext.setAttribute("javax.servlet.context.tempdir", getScratchDir());
webAppContext.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern",
".*/[^/]*servlet-api-[^/]*\\.jar$|.*/javax.servlet.jsp.jstl-.*\\.jar$|.*/.*taglibs.*\\.jar$");
webAppContext.setAttribute("org.eclipse.jetty.containerInitializers", jspInitializers());
webAppContext.setAttribute(InstanceManager.class.getName(), new SimpleInstanceManager());
webAppContext.addBean(new ServletContainerInitializersStarter(webAppContext), true);
webAppContext.setWar("C:\\temp\\cas-server-webapp-4.2.1.war");
server.setHandler(webAppContext);
final JdbcDataSource jdbcDataSource = new JdbcDataSource();
jdbcDataSource.setURL("jdbc:h2:c:\\temp\\teste;mv_store=false");
jdbcDataSource.setUser("sa");
jdbcDataSource.setPassword("sa");
jdbcDataSource.getConnection();
new org.eclipse.jetty.plus.jndi.Resource(webAppContext, "jdbc/mydatasource", jdbcDataSource);
server.start();
server.join();
}
/**
* Establish Scratch directory for the servlet context (used by JSP
* compilation)
*/
private static File getScratchDir() throws IOException {
File tempDir = new File(System.getProperty("java.io.tmpdir"));
File scratchDir = new File(tempDir.toString(), "embedded-jetty-jsp");
if (!scratchDir.exists()) {
if (!scratchDir.mkdirs()) {
throw new IOException("Unable to create scratch directory: " + scratchDir);
}
}
return scratchDir;
}
/**
* Ensure the jsp engine is initialized correctly
*/
private static List<ContainerInitializer> jspInitializers() {
JettyJasperInitializer sci = new JettyJasperInitializer();
ContainerInitializer initializer = new ContainerInitializer(sci, null);
List<ContainerInitializer> initializers = new ArrayList<ContainerInitializer>();
initializers.add(initializer);
return initializers;
}
}
2）使用Maven我可以执行目标 jetty：run-war ，它会在Jetty嵌入式服务器中启动WAR覆盖。

正如您所看到的，两种解决方案都将CAS启动到一个独立的Web服务器中，但我想要达到的是Jenkins所做的事情，一个可以通过简单的命令行启动的WAR文件：java -jar CAS.war
有没有办法在通过Jetty嵌入式运行的WAR文件中导出Maven构建？

CAS v5和Spring Boot会自动提供此行为。不要重新发明轮子。
