Und config-Klasse

import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication 
@ComponentScan("com.example.demo") 
public class AppConfig extends SpringBootServletInitializer { 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(AppConfig.class); 
    } 

    public static void main(String[] args) throws Exception { 
     SpringApplication.run(AppConfig.class, args); 
    } 


}

Ich verwende Spring Boot und Resolver JSTL. Meine Version Spring Boot ist 1.5.3 RELEASE.

spring.mvc.view.prefix: /WEB-INF/jsp/ 
spring.mvc.view.suffix: .jsp

Was könnte falsch sein?

Möchten Sie eine bereitstellbare WAR-Datei erstellen? Sehen Sie sich diesen Link an: https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html –

Danke. Es funktioniert: D –

Ich kann nicht herausfinden, was Sie tun möchten. Also, was ist Ihr Zweck, Spring Boot zu verwenden?
Wenn Sie einen RESTful-Service entwickeln möchten, erstellen Sie einfach Ihr Code-Paket als JAR.

Meiner Ansicht nach ist Fehler Stack nicht mit Spring-Boot-Anwendung zu bauen. Es könnte die Möglichkeit sein, die Abhängigkeiten zu konfliktieren, da ich auch mit dieser Art von Situation konfrontiert bin. –

Ich habe auch mit dem gleichen Problem konfrontiert und die Ursache war mit fehlenden Abhängigkeit verbunden. Das Problem bezog sich nicht auf Spring Boot Starter. Also, ich habe einfach versucht, eine weitere Abhängigkeit hinzufügen, die gut mit Ihrem JSTL funktioniert

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>javax.servlet-api</artifactId> 
</dependency>
