Spring Boot Hello World Example – Thymeleaf

In this article, we will show you how to develop a Spring Boot web application, using Thymeleaf view, embedded Tomcat and package it as an executable JAR file.

Technologies used :

Spring Boot 2.1.2.RELEASE
Spring 5.1.4.RELEASE
Thymeleaf 3.0.11.RELEASE
Tomcat embed 9.0.14
JUnit 4.12
Maven 3
Java 8

1. Project Directory

2. Maven

Put spring-boot-starter-web and spring-boot-starter-thymeleaf, it will get anything we need to develop a Spring MVC + Thymeleaf web application, including the embedded Tomcat server.

3. Developer Tools


	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-devtools</artifactId>
		<optional>true</optional>
	</dependency>

This spring-boot-devtools helps to disable the caches and enable hot swapping so that developers will always see the last changes. Good for development. Read this – Spring Boot – Developer tools Try to modify the Thymeleaf templates or properties files, refresh the browser to see the changes take effect immediately.

For Eclipse IDE, it is integrated well with spring-boot-devtools.
For Intellij IDEA, extra steps are required, read this reload static file is not working

4. Spring Boot + MVC

4.1 A simple controller.

WelcomeController.java


package com.mkyong.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.Arrays;
import java.util.List;

@Controller
public class WelcomeController {

    // inject via application.properties
    @Value("${welcome.message}")
    private String message;

    private List<String> tasks = Arrays.asList("a", "b", "c", "d", "e", "f", "g");

    @GetMapping("/")
    public String main(Model model) {
        model.addAttribute("message", message);
        model.addAttribute("tasks", tasks);

        return "welcome"; //view
    }

    // /hello?name=kotlin
    @GetMapping("/hello")
    public String mainWithParam(
            @RequestParam(name = "name", required = false, defaultValue = "") 
			String name, Model model) {

        model.addAttribute("message", name);

        return "welcome"; //view
    }

}

4.2 Create a class and annotate with @SpringBootApplication. In IDE, run this class to start the entire web application.

StartWebApplication.java


package com.mkyong;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class StartWebApplication {

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

}

5. Thymeleaf + Static files

Note
Read this Spring Boot Serving static content to understand the resource mapping.

5.1 For Thymeleaf template files, put in src/main/resources/templates/

src/main/resources/templates/welcome.html


<!DOCTYPE HTML>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <title>Spring Boot Thymeleaf Hello World Example</title>

    <link rel="stylesheet" th:href="@{webjars/bootstrap/4.2.1/css/bootstrap.min.css}"/>
    <link rel="stylesheet" th:href="@{/css/main.css}"/>

</head>

<body>

<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
    <a class="navbar-brand" href="#">Mkyong.com</a>
</nav>

<main role="main" class="container">

    <div class="starter-template">
        <h1>Spring Boot Web Thymeleaf Example</h1>
        <h2>
            <span th:text="'Hello, ' + ${message}"></span>
        </h2>
    </div>

    <ol>
        <li th:each="task : ${tasks}" th:text="${task}"></li>
    </ol>

</main>
<!-- /.container -->

<script type="text/javascript" th:src="@{webjars/bootstrap/4.2.1/js/bootstrap.min.js}"></script>
</body>
</html>

5.2 Spring Boot common application properties

src/main/resources/application.properties


welcome.message: Mkyong

spring.thymeleaf.cache=false

5.3 For Static files like CSS or JS, put in src/main/resources/static/

src/main/resources/static/css/main.css


body {
  padding-top: 5rem;
}
.starter-template {
  padding: 3rem 1.5rem;
  text-align: center;
}

h1{
	color:#0000FF;
}

h2{
	color:#FF0000;
}

6. Unit Test

MockMvc to test the Spring MVC controller.

WelcomeControllerTest.java


package com.mkyong;

import com.mkyong.controller.WelcomeController;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.web.servlet.ModelAndView;

import java.util.Arrays;
import java.util.List;

import static org.hamcrest.Matchers.containsString;
import static org.hamcrest.Matchers.is;
import static org.hamcrest.core.IsEqual.equalTo;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = WelcomeController.class)
public class WelcomeControllerTest {

    @Autowired
    private MockMvc mockMvc;

    List<String> expectedList = Arrays.asList("a", "b", "c", "d", "e", "f", "g");

    @Test
    public void main() throws Exception {
        ResultActions resultActions = mockMvc.perform(get("/"))
                .andExpect(status().isOk())
                .andExpect(view().name("welcome"))
                .andExpect(model().attribute("message", equalTo("Mkyong")))
                .andExpect(model().attribute("tasks", is(expectedList)))
                .andExpect(content().string(containsString("Hello, Mkyong")));

        MvcResult mvcResult = resultActions.andReturn();
        ModelAndView mv = mvcResult.getModelAndView();
        //
    }

    // Get request with Param
    @Test
    public void hello() throws Exception {
        mockMvc.perform(get("/hello").param("name", "I Love Kotlin!"))
                .andExpect(status().isOk())
                .andExpect(view().name("welcome"))
                .andExpect(model().attribute("message", equalTo("I Love Kotlin!")))
                .andExpect(content().string(containsString("Hello, I Love Kotlin!")));
    }


}

7. Demo


$ mvn spring-boot:run

: Tomcat initialized with port(s): 8080 (http)
: Starting service [Tomcat]
: Starting Servlet engine: [Apache Tomcat/9.0.14]

: Tomcat started on port(s): 8080 (http) with context path ''
 Started StartWebApplication in 1.858 seconds (JVM running for 2.222)

URL = http://localhost:8080

URL = http://localhost:8080/hello?name=abc

8. Create an executable JAR

For deployment, just normal Maven package to create an executable JAR file.


$ mvn clean package

$ java -jar target\web-thymeleaf-1.0.jar

Download Source Code

$ git clone https://github.com/mkyong/spring-boot.git
$ cd web-thymeleaf
$ mvn spring-boot:run

Is there any way to serve HTML, CSS, and JavaScript files outside of the WAR file instead of being in the resources directory?

  private int id;
  @Column(name = “MARCA”)
  private String marca;

  @OneToMany(mappedBy = “marcaVo”, cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
  @Fetch(FetchMode.SUBSELECT)

  private List<ProductoVo> listProductoVo;

PRODUCTOS
@Entity(name = “ProductoVo”)

Hello
I am using spring boot 2 (v2.5.1) with thymeleaf maven.

When I am using server.servlet.context-path in application.properties, redirected pages are giving 404.

Hi!
Why, at the added dependence spring-boot-starter-mvc in an example “webflux-thymeleaf” there is mistake?
How to overcome it?

org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: “class path resource [templates/index.html]”)
…
Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field ‘name’ cannot be found on object of type ‘org.thymeleaf.spring5.context.webflux.ReactiveDataDriverContextVariable’ – maybe not public or not valid?

be careful not to place directly :
– WelcomeController.java
– StartWebApplication.java
under the folder java directly.

You must put the controller and the main class at least in a package (or many subpackages) with the name of your choice, otherwise the application will not launch.

The command mvn dependancy:tree may not work with windows.

  This example is tested with Spring Boot 2.1.2.RELEASE, for those who hits errors, the first try is upgrade your Spring Boot to latest.

To those having errors with this example, simple comment out this line of code from your pom.xml
Then, build and Run your application.

org.springframework.boot
spring-boot-devtools

  To those having errors with this example, simple comment out this dependency line of code from your “pom.xml” file
  Then, build and Run your application.
  
  org.springframework.boot
  spring-boot-devtools
  true

  Change @Controller to @RestController in the controller file.

css files couldn’t include. I did like your sample but I got this error “NetworkError: 404 Not Found – http://localhost:8080/static/css/main.css“. How can I solve this?

  Brother, you can’t be looking directly, cause it’s Spring Boot. You @RequestMapping (“/”) it mean http://localhost:8080/

  1. add
  
  org.webjars
  webjars-locator
  
  2. remove /static/ , only href=/css/main.css

Hey, I got the error message: “Error resolving template “welcome”, template might not exist or might not be accessible by any of the configured Template Resolvers”.

Then I found this thread on StackOverflow ( https://stackoverflow.com/questions/44361064/error-resolving-template-welcome-template-might-not-exist-or-might-not-be-acc )

I just added the following dependency and it worked:
org.springframework.boot spring-boot-starter-web

Hi, what is the correct way to change the .html files path? I want them inside webapp/WEB-INF/templates. I’ve tried with the templateResolver setPrefix official thymeleaf doc, adding at my application.yml the spring:thymeleaf:prefix: classpath:WEB-INF/templates (without classpath…) with another @bean definitios in stackoverflow but not working in any way… Any idea or advice?
