SPRING IN ACTION FIFTH EDITIO, PASO A PASO

ANALISIS Y DESARROLLO PASO A PASO DEL LIBRO SPRING IN ACTION 5TH EDITION

PASO NUMERO 1

INSTALAR INTELLIJ COMUNNITY EDITION,

ABRIR EL CODIGO DE SPRING IN ACTION FIFHT EDITION

EL PASO DE USAR SCRIPT DE CONFIGURACION ES MUY IMPORTANTE TE APARECE EN LA PARTE INFERIOR DERECHA, CONFIGURACION DE INTELLIJ, QUE ES SUPERIOR A ECLIPSE FOR SURE.

DE OTRA MANERA TE ENVIA UN ERROR DE

Non-resolvable parent POM in SpringBoot

HAY QUE DIRECCIONAR BIEN EL JAVA_HOME, MVN Y USAR JDK Y NO JRE, ESTO ES IMPORTANTE PARA QUE COMPILE BIEN. REVISAR BIEN VARIABLES DE AMBIENTE TANTO DE USUARIO COMO GLOBALES

VERSION CORRECTA EN JAVA_HOME Y PATH LOCAL COMO DE USUARIO

C:\Program Files\Java\jdk1.8.0_271

C:\Users\rober>java -version

java version "1.8.0_271"

Java(TM) SE Runtime Environment (build 1.8.0_271-b09)

Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)

C:\Users\rober\Desktop\DELROJA_2020 ORDEN TOTAL\spring-in-action-5-samples-master\spring-in-action-5-samples-master\ch01\tacos>mvn spring-boot:run

mvn clean

mvn install

main

package tacos;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication   // <1>
public class TacoCloudApplication {

  public static void main(String[] args) {

    SpringApplication.run(TacoCloudApplication.class, args); // <2>
  }

}

package tacos;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller            // <1>
public class HomeController {

  @GetMapping("/")     // <2>
  public String home() {

    return "home";     // <3>
  }

}

VEMOS CLARAMENTE QUE ESTA EL CONTROLLER Y GETMAPPING ANNOTATIONS

REGRESA EL HOME, EL HOME.HTML

EN STATIS IMAGES SE REGRESA LA IMAGEN DE TIPO ESTATICO, ES DECIR CONSTANTE
