Join For FreeIn this tutorial, I am going to show you how easy it is to create a web application with Spring Boot 2, along with the embedded Tomcat + JSP template and JSP views.
What You'll Need
1. Project Structure
You can get the blueprint from the Spring Initializer page.
2. Project Dependencies

3. Configuration
3.1 Application Configurations
This SpringBootServletInitializer runs a SpringBootJspApplication from a traditional WAR deployment
SpringBootJspApplication.java
xxxxxxxxxx
package com.eprogrammerz.examples.spring.springbootjsp;
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;
@SpringBootApplication
public class SpringBootJspApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootJspApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(SpringBootJspApplication.class, args);
}
}
3.2 Resources
application.properties
xxxxxxxxxx
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
4. Controller and View Template
4.1 Create a Controller With Simple Method Handling the Base Request
xxxxxxxxxx
package com.eprogrammerz.examples.spring.springbootjsp.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
public class HelloController {
@GetMapping({"/", "/hello"})
public String hello(Model model, @RequestParam(value="name", required=false, defaultValue="World") String name) {
model.addAttribute("name", name);
return "hello";
}
}
4.2 Add JSP View as a Template
For JSP files, put in src/main/webapp/WEB-INF/jsp/
xxxxxxxxxx
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Hello ${name}!</title>
</head>
<body>
<h2 class="hello-title">Hello ${name}!</h2>
</body>
</html>
5. Run With Maven
You can run your application with a bash command at the project root directory:
xxxxxxxxxx
mvn clean spring-boot:run
Then go to localhost:8080 to test out your application.
That's it!
