springboot创建可执行文件jar

要创建可执行文件 jar，我们需要将spring-boot-maven-plugin添加到我们的pom.xml中。要做到这一点，请在dependencies部分下方插入以下行：

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

保存pom.xml并从命令行运行mvn package，如下所示：

$ mvn package

要运行该应用程序，请使用java -jar命令，如下所示：

$ java -jar target/myproject-0.0.1-SNAPSHOT.jar
