display application version in title using thymeleaf and springboot

I know I'm late but Patrick's answer and Spring docs greatly helps in this matter.

1. If your pom.xml use spring-boot-starter-parent as parent, you can use @project.version@ to get version (and any other Maven properties) in your application.properties file. According to Spring docs:

You can automatically expand properties from the Maven project using resource filtering. If you use the spring-boot-starter-parent you can then refer to your Maven ‘project properties’ via @..@ placeholders

Maven pom.xml:

<groupId>com.foo</groupId>
<artifactId>bar</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>Foo</name>
<description>Bar</description>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.4.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

Spring application.properties:

[email protected]@

2. Then a class annotated with @ControllerAdvice can be used to inject version as model attribute.

@ControllerAdvice
public class ControllerAdvice {

    @Value("${foo.app.version}")
    private String applicationVersion;

    @ModelAttribute("applicationVersion")
    public String getApplicationVersion() {
        return applicationVersion;
    }

}

3. Finally this model attribute can be accessed by Thymeleaf as any other.

<th:block th:text="${applicationVersion}"></th:block>

Hope this helps!

Here is the simplest way I've found : In my controller :

@ModelAttribute("version")
public String getVersion() throws IOException {
    logger.info("ModelAttribute to get application version");
    Manifest manif = new Manifest(
            Application.class.getResourceAsStream("/META-INF/MANIFEST.MF"));
    String version = (String) manif.getMainAttributes().get(
            Attributes.Name.IMPLEMENTATION_VERSION);
    return version;
}

In my htm page :

<h4 th:text="${version}">Version</h4>
