    Spring Boot JSP Example

    This example shows how to render a jsp in Spring Boot application

    Step 1) Create pom.xml and add below maven dependency


    Step 2) Create WebApplication class

    package com.example.demo;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    public class WebApplication extends SpringBootServletInitializer {
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(WebApplication.class);
        public static void main( String[] args ) {
        	SpringApplication.run(WebApplication.class, args);  

    Step 3) Create HelloWorldController class which will expose endpoint to return a String which will be displayed by the JSP page

    package com.example.demo;
    import java.util.Map;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.GetMapping;
    public class HelloWorldController {
        public String hello(Map<String, Object> model) {
        	model.put("message", "Hello world JSP example");
            return "helloWorld";

    Step 4) Create helloWorld.jsp file under src/main/webapp/WEB-INF/jsp folder

    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
            <title>Spring Boot JSP example</title>
            <link href="css/main.css" rel="stylesheet">
            <h1>Spring Boot JSP Example</h1>
            <h2>Message: ${message}</h2>

    Step 5) Create application.properties file under src/main/resources folder

    spring.mvc.view.prefix: /WEB-INF/jsp/
    spring.mvc.view.suffix: .jsp       

    Step 6) Create main.css file under src/main/resources/static/css folder

    spring.mvc.view.prefix: /WEB-INF/jsp/
    spring.mvc.view.suffix: .jsp     

    Maven Build

    Step 7) Running WebApplication

    Console Output :

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

    Step 8) Testing HelloWorldApplication

    Open any browser and launch http://localhost:8080. You will see 'Hello World' message displayed in the broswer.
