java アプリケーションを実行するために、組み込みの tomcat(v_ 8.0.33 ) を使用しています。コンソールに次のエラーがスローされます。

正しい web.xml ファイルへのマッピングだと思いますが、どういうわけかタグを解析できず、理由がわかりません。このTomcatのバージョンが原因ですか(何かが非推奨で、私が使用している可能性があります)?

以下は私のweb.xmlです：

<?xml version="1.0" encoding="UTF-8"?>

webapp-runner の XML 解析ロジックに問題があるため、回避策は web.xml デプロイメント記述子の使用を避けることです。

代わりに--> tomcat インスタンスを含むMainクラスで使用します。

Tomcat.addServlet(context, "yourServletName", resourceConfig());
context.addServletMapping("/yourApi/*", "yourServletName");



 private ServletContainer resourceConfig() {
        return new ServletContainer(new ResourceConfig(
                new ResourceLoader().getClasses()));
    }

ResourceLoader.java

import java.util.HashSet;
import java.util.Set;

import javax.ws.rs.core.Application;



public class ResourceLoader extends Application{

    @Override
    public Set<Class<?>> getClasses() {
        final Set<Class<?>> classes = new HashSet<Class<?>>();

        // register root resource
        classes.add(classWhereYouDefinedUrlEndpoint.class);
        return classes;
    }

これはあなたの時間を節約するかもしれません:)
