Spring-Boot-Anwendung: ApplicationContextException: EmbeddedWebApplicationContext kann nicht gestartet werden

Question

Wenn ich diese Spring Boot-Anwendung ausführen, bekomme ich eine Ausnahme.

Code:

package com.example.extract.boot; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.web.support.SpringBootServletInitializer; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 

@Configuration 
@ComponentScan(basePackages= "com.example.extract") 
@EnableAutoConfiguration 
//@SpringBootApplication 
public class Demo1Application extends SpringBootServletInitializer { 

    private static Class<Demo1Application> applicationClass = Demo1Application.class; 

    public static void main(String[] args) { 
     System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH","true"); 
     SpringApplication.run(applicationClass, args); 
    } 
    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(applicationClass); 

    } 
}

Ich habe alles versucht, die in Stackoverflow in verfügbar erwähnt wird, aber immer noch die gleiche Ausnahme bekommen .

Answer 1

Bitte erwähnen Sie die Verpackung als "Jar" ​​anstelle von "Krieg", erstellen Sie die Anwendung neu und starten Sie sie neu. Versuchen Sie das und lassen Sie mich wissen, wie es geht.

<packaging>jar</packaging> 

Auch ich sehe, gibt es eine Ausnahme für „Feder-boot-Starter-tomcat“ Abhängigkeit, bitte nehmen Sie es als dies die Ursache zu sein scheint für nicht eingebettet tomcat Behälter zu erfassen.
