直接使用java启动下面的main函数，发现Jetty没有到WEB-INF/lib下面的JAR。代码如下：
/**
* 启动器
*/
public class Launcher {
public static void main(String args[]) throws Exception {
new Launcher().start();
}
void start() throws Exception {
// 服务器的监听端口
Server server = new Server(80);
// 关联一个已经存在的上下文
WebAppContext context = new WebAppContext();
// 设置描述符位置
String path = Launcher.class.getResource("/").getPath();
context.setDescriptor(path + "../web.xml");
// 设置Web内容上下文路径
context.setResourceBase(path + "/../../");
// 设置上下文路径
context.setContextPath("/admin/");
context.setParentLoaderPriority(true);
//开启HTML，CSS，JS热部署
context.setInitParameter("org.eclipse.jetty.servlet.Default.useFileMappedBuffer", "false");
server.setHandler(context);
// 启动
server.start();
server.join();
}

시작할 때
java -cp jetty.jar;WebContentWEB-INFclasses Launcher를 사용하여 프로젝트를 시작하세요.오류 로그를 보면
org.springframework.core.JdbcTemplate클래스를 찾을 수 없다는 것을 알 수 있습니다. 문제의 소스코드는 아래classes비즈니스 코드에 있습니다.그래서 하나가 형성되었습니다:
으아악에는 이러한 종속성 구조가 있으므로 Spring 컨테이너를 초기화할 때
AppCloassLoader에서 클래스를 초기화하면(Spring에 따라) Spring 클래스JdbcTemplate를 쿼리할 수 없다는 것을 발견했습니다. 이는 로더의双亲委托机制때문입니다.해결책:
으아악시작 시 모든 libs와 jar 지정
또는 강제 지정, jetty Launcher 시작으로 로드된 클래스 경로를 사용하지 마세요:
context.setParentLoaderPriority(false);start.jar과 같은 캡슐화된 부두 실행 프로그램을 사용하여 시작할 때 특정
classpath설정해 보셨나요
context.setExtraClasspath(你的WEB-INF/lib)?
