## 背景 ##

springboot可以通过maven直接打包称为可执行的jar。而不需要打成war包后放入Tomcat才能启动。

### step1 pom.xml文件 ###

将下面代码插入 的下部

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

### step2 ###

运行右侧maven的lifecycle点击 package会执行打包。执行log可以看到jar包的位置。

[INFO] --- maven-jar-plugin:3.1.1:jar (default-jar) @ springboot-helloworld ---
    [INFO] Building jar: D:\Appdata\idea\springboothelloworld\target\springboot-helloworld-1.0-SNAPSHOT.jar

## step 3执行 ##

通过 java -jar 包名可以直接执行

D:\>java -jar D:\Appdata\idea\springboothelloworld\target\springboot-helloworld-1.0-SNAPSHOT.jar
