Spring Boot Bootstrap

Boostrap was originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.

In this technical post I will show you how to add Bootstrap to your Spring Boot project. In order to get the setup for this example, please refer my previous post Spring Boot JPA

First you need to add Bootstrap dependency to your project, the way you should do it is add it as a Bower plugin to your build.gradle file in this way, you delegate to Gradle the responsability to orchestrate Bootstrap dependency management.

plugins {
  id 'com.craigburke.bower-installer' version '2.5.1'
}

bower {
  installBase = 'src/main/resources/static/assets/third-party'
  'bootstrap'('3.3.7'){
    source '**'
  }
}

Next, we are going to add header and footer to a simple html page using navbar component.

Header

<nav class="navbar navbar-inverse navbar-fixed-top">
  <font color="white">Spring Boot</font>
</nav>

Footer

<footer>
  <nav class="navbar navbar-inverse navbar-fixed-bottom">
    <a class="navbar-brand" href="https://github.com/josdem/spring-boot-jpa">josdem 2018</a>
  </nav>
</footer>

Do not forget to add Bootstrap style sheet in your head section

<head>
  <link rel="stylesheet" th:href="@{/assets/third-party/bootstrap/dist/css/bootstrap.min.css}" />
</head>

Another component we are going to use is Jumbotron which is a kind of viewport to showcase messages on your site.

<div class="jumbotron">
  <div class="container">
    <h1>Welcome!</h1>
    <p>Spring Boot Workshop</p>
    <a href="https://github.com/josdem/spring-boot-jpa" class="btn btn-primary btn-lg" role="button">Learn more</a>
  </div>
</div>

This is a complete html example with header, footer, form and jumbotron integrated.

<html>
<head>
  <link rel="stylesheet" th:href="@{/assets/third-party/bootstrap/dist/css/bootstrap.min.css}" />
</head>
<body>
  <nav class="navbar navbar-inverse navbar-fixed-top">
    <font color="white">Spring Boot</font>
  </nav>
  <div class="jumbotron">
    <div class="container">
      <h1>Welcome!</h1>
      <p>Spring Boot Workshop</p>
      <a href="https://github.com/josdem/spring-boot-jpa" class="btn btn-primary btn-lg" role="button">Learn more</a>
    </div>
  </div>
  <div class="container">
  <form id="create" th:action="@{/persons}" th:object="${personCommand}" method="post">
    <div class="form-group">
  	  <label class="col-sm-1 col-form-label-lg" for="nickname">Nickname:</label>
  	  <input class="form-control form-control-lg" type="text" name="nickname" th:field="*{nickname}" placeholder="nickname" id="nickname"/>
  	  <label th:if="${#fields.hasErrors('nickname')}" th:errors="*{nickname}"></label>
    </div>
  	<br/>
    <div class="form-group">
  	  <label class="col-sm-1 col-form-label-lg" for="email">Email:</label>
  	  <input class="form-control form-control-lg" type="text" name="email" th:field="*{email}" placeholder="email" id="email"/>
  	  <label th:if="${#fields.hasErrors('email')}" th:errors="*{email}"></label>
    </div>
  	<br/><br/>
  	<button class="btn btn-success" id="btn-success" type="submit">Submit</button>
  </form>
  </div>
  <footer>
    <nav class="navbar navbar-inverse navbar-fixed-bottom">
      <a class="navbar-brand" href="https://github.com/josdem/spring-boot-jpa">josdem 2018</a>
    </nav>
  </footer>
</body>
</html>
