Spring boot can't show jsp page but run Controller mapping method

Question

I have a problem in my spring boot application : I can not show the jsp page but it's run the Controller method mapped to that page .

main Class :

package com.example.souk;

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

@SpringBootApplication
public class Souk5Application {

    public static void main(String[] args) {
        SpringApplication.run(Souk5Application.class, args);
    }
}

the Controller :

package com.example.souk;

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

@Controller
public class Souk5Controller {

    @RequestMapping("/afficher")
    public String test(){
        System.out.println("je suis dans souk 5 controller ");
        return "afficher";
    }
}

application.properties:

spring.datasource.url=jdbc:mysql://localhost:3306/kijiji
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-AUTO=update
spring.jpa.properties.hibernate.dialct=org.hibernate.dialect.MySQL5Dialect

As mentioned by Rishikesh add dependencies in pom.xml and do the following also.

You need to extend your Main class from SpringBootServletInitializer.

@SpringBootApplication 
public class Souk5Application extends SpringBootServletInitializer{

     @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Souk5Application .class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Souk5Application.class, args);
    }
}

Note : Make sure your directory is as correct as below (Sources : sitesbay):

Add below dependencies to your POM file:

<dependency>
 <groupId>org.apache.tomcat.embed</groupId>
 <artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
 <groupId>javax.servlet</groupId>
 <artifactId>jstl</artifactId>
</dependency>

Place the JSP templates under src/main/resources/META-INF/resources/WEB-INF/jsp/

In your application.properties: Should update to below:

spring.mvc.view.prefix= /WEB-INF/jsp/

spring.mvc.view.suffix= .jsp
