我試圖安裝一個彈簧啓動的應用程序與嵌入式Jetty服務器。這臺服務器應該運行一個小的webapp。但是,在開始時,我會在加載war文件之後發現以下異常。嵌入式碼頭:ServletContext的要求配置默認的servlet處理

我已經下調代碼到最低限度,仍然得到錯誤。
主要
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class ServerApplication {
public static void main(String[] args) {
SpringApplication.run(ServerApplication.class);
}
}
配置
@Configuration
@EnableAutoConfiguration
public class JettyServerCustomizer implements EmbeddedServletContainerCustomizer {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
if (container instanceof JettyEmbeddedServletContainerFactory) {
customizeJetty((JettyEmbeddedServletContainerFactory) container);
}
}
public void customizeJetty(
JettyEmbeddedServletContainerFactory containerFactory) {
containerFactory.addServerCustomizers(jettyServerCustomizer());
}
@Bean
public JettyServerCustomizer jettyServerCustomizer() {
return new JettyServerCustomizer() {
@Override
public void customize(Server server) {
String jetty_home = System.getProperty("jetty.home","..");
WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setWar(jetty_home+"/webapps/sample.war");
server.setHandler(webapp);
}
};
}
}
有什麼建議?謝謝!
更新
試圖從Strelok我得到這個錯誤,而不是建議後。
