Spring-boot を使用して組み込み tomcat サーバーでアプリケーションを実行しようとしています。JNDI リソースと環境を XML ファイルで構成し、アプリケーションの src/main/webapp/META-INF/context.xml の下に配置しています。このアプリケーションを標準のサーブレット コンテナーにデプロイすると、動作します。しかし、組み込みサーバーを使用して起動すると、コンテキスト ファイルに存在する JNDI リソースが認識されません。
次のコードを使用して、プログラムでコンテキスト ファイルを embeddedTomcatContainer に追加しようとしました。このブログから引用-
@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
Tomcat tomcat) {
tomcat.enableNaming();
Context context = new StandardContext();
File f = new File("D:\\Workspace\\SpringBoot\\src\\main\\webapp\\META-INF\\context.xml");
try {
context.setConfigFile(f.toURI().toURL());
tomcat.getHost().addChild(context);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return super.getTomcatEmbeddedServletContainer(tomcat);
}
しかし、次の例外が発生しています。context.xml ファイルを組み込みの tomcat サーバーに追加する方法を教えてください。

また、さらにいくつかの tomcat API を使用して context.xml ファイル (複数の JNDI リソースと環境が定義されている) を組み込みサーバー インスタンスにロードしようとしましたが、Null Pointer Exception が引き続き発生します。使用しようとしたさまざまな API を PFB します。
1. tomcat.addContext("/my-boot", System.getProperty("user.dir")+ "/src/main/webapp/META-INF/context.xml");
2. StandardContext context = new StandardContext();
context.setDefaultContextXml(System.getProperty("user.dir") + "/src/main/webapp/META-INF/context.xml");
tomcat.getHost().addChild(context);
どちらのアプローチでも、Tomcat がリソースの名前を取得しようとしているときに NullPointerException が発生します。API メソッドの名前からして、これを実現する方法が必要だと思います。これを手伝ってください。
