How to use the Spring Boot Maven plugin

Maven

Maven users can inherit spring-boot-starter-parentthe project to get suitable default settings. This parent project provides the following features:

• The default compilation level is Java 1.6
• Source code encoded as UTF-8
• A dependency management node that allows you to omit labels for common dependencies <version>, inherited from spring-boot-dependenciesPOM.
• Appropriate resource filtering
• Appropriate plugin configuration ( exec plugin , surefire , Git commit ID , shade )
• Resource filtering for application.propertiesandapplication.yml

One last note: since default configuration files receive Spring-style placeholders ( ${...}), Maven filtering uses @..@placeholders instead (you can use Maven properties resource.delimiterto override this).

Inherit from starter parent

To configure your project inheritance spring-boot-starter-parentsimply set parentto:

<!-- Inherit defaults from Spring Boot -->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.0.BUILD-SNAPSHOT</version>
</parent>

Note : You should only need to specify the Spring Boot version on this dependency. If importing other starters, you can safely omit the version number.

Using Spring Boot without a parent POM

Not everyone likes to inherit spring-boot-starter-parentPOM. You may need to use a company standard parent, or you may prefer to declare all Maven configuration explicitly.

If you don't , you still get the benefits of dependency management spring-boot-starter-parentby using a dependency:scope=import

<dependencyManagement>
     <dependencies>
        <dependency>
            <!-- Import dependency management from Spring Boot -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>1.3.0.BUILD-SNAPSHOT</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

change java version

spring-boot-starter-parentChoose a fairly conservative Java compatibility strategy. If you follow our advice and use a recent Java version, you can add a java.versionproperty:

<properties>
    <java.version>1.8</java.version>
</properties>

Using the Spring Boot Maven plugin

Spring Boot includes a [Maven plugin](…/VIII. Build tool plugins/58. Spring Boot Maven plugin.md), which can package the project into an executable jar. If you want to use it, you can add the plugin to <plugins>the node:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Note : If using the Spring Boot starter parent pom, you only need to add the plugin without configuring it, unless you want to change settings defined in the partent.
