和配置類

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


@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); 
    } 


}

我使用spring引導和解析器jstl。我的版本spring引導是1.5.3 RELEASE。

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

出了什麼問題？

你想創建一個可部署的war文件？看看這個鏈接：https：//docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html –

謝謝。它的工作原理：D –

我無法弄清楚你想要做什麼。那麼，您使用Spring Boot的目的是什麼？
如果您想開發一個RESTful服務，只需將您的代碼包構建爲JAR。

按照我的觀點，錯誤堆棧與建立彈簧引導應用程序無關。這可能是與依賴關係相沖突的機會，因爲我也面臨這種情況。 –

我也遇到了同樣的問題，根本原因與缺失依賴有關。這個問題與Spring引導啓動器無關。所以，我只是想增加一個依賴這是工作的罰款與JSTL
