Issue
In my SpringBoot application I have 2 controllers. I am trying to render JSP page but unable to do so. I have <app-root> in JSP page which points to Angular application.
On hitting http://localhost:8081//api/project1/mission/home I get below error.
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
I have tried many solutions but none of them are working. I need help. Thank you

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;
@Controller
@RequestMapping(path = "/")
public class FirstController {
private String message = "Hi";
@GetMapping

System.out.println(this.message);
return "welcome";
}
}
AnotherController.js
package com.google.mission.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;
@Controller
@RequestMapping(path = "/home")
public class AnotherController {
private String message = "Hi";
@GetMapping
public String serveTemplate(Map<String, Object> model) {
model.put("message", this.message);
return "welcome";
}
}
Solution
Adding the below dependency should solve the error.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
