Not able to run jsp file in spring boot using embedded tomcat server
Question
I have created a simple SpringBoot project to view jsp file.
Here is my Project tree -
This is MyappApplication.java
package com.simplespringboot.myapp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MyappApplication {
public static void main(String[] args) {
SpringApplication.run(MyappApplication.class, args);
System.out.println("Let's get started");
}
}
This is TestController.java
package com.simplespringboot.myapp;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class TestController {
@RequestMapping("/")
@ResponseBody
public String handler() {
System.out.println("I am handler method");
return "HI there ";
}
@RequestMapping("/home")
public String home() {
System.out.println("I am home method");
return "home";
}
}
Application.properties
spring.mvc.view.prefix= /views/
spring.mvc.view.suffix=.jsp
This is my home.jsp file -
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
This is home view
</body>
</html>
This is my POM.xml file -

Whenever I am trying to my application this error is coming in the terminal -

Open Command Palette and choose Maven: Add a dependency , type the missing jar name:
This is equals to add the following code in pom.xml:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<version>10.0.4</version>
</dependency>
Then rebuild the project and see if the question goes away.
