SpringBootWebApplication.java
package com.mkyong;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootWebApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(SpringBootWebApplication.class, args);
}
}
WelcomeController.java
package com.mkyong;
import java.util.Map;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class WelcomeController {
// inject via application.properties
@Value("${welcome.message:test}")
private String message = "Hello World";
@RequestMapping("/")
public String welcome(Map<String, Object> model) {
model.put("message", this.message);
return "welcome";
}
}
Page welcome.jsp does not have access to
If welcome.jsp is replaced with welcome.html, then the output is correct (in this case, the problem does not arise)
but I can't access the welcome.jsp file in this Spring boot application
Why does html have access and why does jsp not have access?
please give a solution

I think it was the Spring version: I change the version to 1.4.1, then> mvn clean install it worked for me. And I am using
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
hope this helps
