Spring Boot web application example:

Here are steps to create a Spring boot web application example Using JSP.

Project structure:

Spring boot project structure

Tools used for creating below project:

Spring Boot 1.5.3.RELEASE
Spring 4.3.8.RELEASE
Tomcat Embed 8
Maven 3
Java 8
Eclipse

Step 1: Create a dynamic web project using maven in eclipse named “SpringBootHelloWorldExample”.

Maven dependencies:

Step 2: Change pom.xml as below:


<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

<name>SpringBootHelloWorldExample Maven Webapp</name>

</build>

</project>

The spring-boot-starter-parent provides you all maven defaults required for any spring project.
Since we are developing a web application, we also need to add spring-boot-starter-web dependency.
This will include additional dependencies such Spring boot, tomcat etc which are required for this application.
If you notice, we did not provide any version for specific components. You just need to provide version no.(1.5.3.RELEASE) for spring boot.
step 3: Create a package named "org.arpit.java2blog.springboot"
create a controller class named "HelloWorldController.java"


package org.arpit.java2blog.springmvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {

 @RequestMapping("/helloworld")
 public ModelAndView hello() {

  String helloWorldMessage = "Hello world from java2blog!";
  return new ModelAndView("hello", "message", helloWorldMessage);
 }
}

package org.arpit.java2blog.springmvc.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

@Controller

public class HelloWorldController {

@RequestMapping("/helloworld")

public ModelAndView hello() {

String helloWorldMessage = "Hello world from java2blog!";

return new ModelAndView("hello", "message", helloWorldMessage);

}

As request first goes to dispatcherServlet and it redirects to the controller class. Here @Controller depicts that this is our controller class. @RequestMapper is used to map incoming HTTP request to handler method(hello() in above controller).So hello() method of HelloWorldController.java will handle GET request from dispatcher.So when we have url of


http://localhost:8080/helloworld or
http://localhost:8080/helloworld.html

http://localhost:8080/helloworld or

http://localhost:8080/helloworld.html

above method will get called.

Step 4: Create a package named “org.arpit.java2blog”
create a class named “SpringBootHelloWorldApplication.java”


package org.arpit.java2blog;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootHelloWorldApplication {

    public static void main(String[] args) 
    {
        SpringApplication.run(SpringBootHelloWorldApplication.class, args);   
    }
}

package org.arpit.java2blog;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class SpringBootHelloWorldApplication {

public static void main(String[] args)

{

SpringApplication.run(SpringBootHelloWorldApplication.class, args);

}

We have just added @SpringBootApplication and it does all the work.
Let’s understand more about this annotation.
@SpringBootApplication is an annotation that adds all of the following:

@Configuration makes the class as a source of bean definitions for the application context.
@EnableAutoConfiguration enables Spring boot to add beans presents in classpath setting and various property setting.
Normally you would add @EnableWebMvc for a Spring MVC application, but Spring Boot adds it automatically when it sees spring-webmvc on the classpath.
This flags the application as a web application and activates key behaviors such as setting up a DispatcherServlet.
@ComponentScan tells Spring to look for other components, configurations, and services in the default package, allowing it to find the controllers.
If specific packages are not defined, scanning will occur from the package of the class that declares this annotation.

Step 5: Create a property file named application.properties as below and put it in src/main/resoures.

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

Above two properties are very much similar to used in springmvc-dispatcher-servlet.xml in Spring MVC example.

Step 6: Modify index.jsp as below:


<%@ page language="java" contentType="text/html; charset=UTF-8"
 pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>HelloWorld</title>
</head>
<body>
<a href="helloworld.html">Click here to read hello message </a>
</body>
</html>

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>HelloWorld</title>

</head>

<body>

<a href="helloworld.html">Click here to read hello message </a>

</body>

</html>

Step 7: Create hello.jsp in /WEB-INF/ folder


<%@ page language="java" contentType="text/html; charset=UTF-8"
 pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello</title>
</head>
<body>
${message}
</body>
</html>

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Hello</title>

</head>

<body>

${message}

</body>

</html>

That’s all about Spring Boot hello world example.
Step 8: It ‘s time to do maven build.

Right click on project -> Run as -> Maven build

Step 9: Provide goals as clean install spring-boot:run (given below) and click on run
Spring boot maven build
you will see below output at console:

Step 10: Let’s test the application now.
As Spring uses embedded tomcat, you can access the project using http://localhost:8080/index.jsp.
Spring boot index
When you click on above link, you will get below screen.
Spring boot Hello World
