내장된 Tomcat 서버에 context.xml 파일을 추가하는 방법
Spring-boot를 사용하여 내장된 Tomcat 서버에서 응용 프로그램을 실행하려고 합니다.애플리케이션의 src/main/webapp/META-INF/context.xml 아래에 있는 XML 파일로 JNDI 리소스 및 환경을 구성합니다.이 애플리케이션을 표준 서블릿 컨테이너에 배포하면 작동합니다.그러나 내장된 서버를 사용하여 시작하면 컨텍스트 파일에 있는 JNDI 리소스를 인식하지 못합니다.
내장된 파일에 컨텍스트 파일을 추가하려고 했습니다.Tomcat Container는 다음 코드를 사용하여 프로그래밍합니다.이 블로그에서 참조 -
@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);
}
하지만 다음과 같은 예외가 발생합니다.누가 내장된 Tomcat 서버에 context.xml 파일을 추가하는 방법을 알려줄 수 있습니까?

내장된 서버 인스턴스에 context.xml 파일(여러 JNDI 리소스 및 환경이 정의되어 있음)을 로드하기 위해 몇 개의 Tomcat API를 더 시도했지만 계속 Null Pointer Exception(Null 포인터 예외)이 발생합니다. PFB는 제가 사용하려고 했던 다른 API를 제공합니다.
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);
두 가지 접근 방식 모두에 대해 NullPointer를 받습니다.Tomcat이 내 리소스의 이름을 가져오는 동안 예외가 발생했습니다.API 방법의 이름으로, 저는 이것을 수행할 수 있는 방법이 있어야 한다고 생각합니다.이것 좀 도와주세요.

@Bean

@Override

tomcat.enableNaming();
Context context = new StandardContext();
File file = new File("D:\\Workspace\\SpringBoot\\src\\main\\webapp\\META-INF\\context.xml");
System.out.println("File Location: "+file.exists());
//First check for file path is true or not. "file.exists()" method will check the location and return true or flase
try {
context.setConfigFile(f.toURI().toURL());
tomcat.getHost().addChild(context);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return super.getTomcatEmbeddedServletContainer(tomcat);
}
getTomcatEmbeddedServletContainer를 configureContext로 교체하는 것이 더 잘 작동하는 것 같습니다.
import org.apache.catalina.startup.ContextConfig;
@Override
protected void configureContext(Context context, ServletContextInitializer[] initializers) {
File f = new File("D:\\Workspace\\SpringBoot\\src\\main\\webapp\\META-INF\\context.xml");
try {
context.setConfigFile(f.toURI().toURL());
} catch (MalformedURLException e) {
e.printStackTrace();
}
ContextConfig config = new ContextConfig();
context.addLifecycleListener(config);
super.configureContext(context, initializers);
}
내장된 Tomcat context.xml을 리소스로 가져오는 다음과 같은 방법을 시도해 볼 수 있습니까?
@Configuration
@EnableAutoConfiguration
@ComponentScan
@ImportResource("classpath:context.xml")
public class Application {
public static void main(String[] args) throws Exception {
new SpringApplicationBuilder()
.showBanner(false)
.sources(Application.class)
.run(args);
}
@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
Tomcat tomcat) {
tomcat.enableNaming();
return super.getTomcatEmbeddedServletContainer(tomcat);
}
};
}
편집: 그러나 위의 구현에서는 내장된 컨테이너 읽기를 사용자 지정하려고 할 때 Spring XSD가 xml 문서를 수동으로 구문 분석해야 합니다.
따라서 context.xml의 내장된 구성을 사용자 정의하기 위해 javaway를 구성하는 것이 항상 더 좋습니다. 여기 다음과 같은 것에 대한 스프링 부트 문서 참조가 있습니다.
아니면 그냥 jndi를 사용하고 싶다면 다음과 같은 것을 참조할 수 있습니다.
이게 도움이 되길 바랍니다.
