springboot前后端以jar包的形式打包发布

下图红框内容，决定了你是打包为jar还是war。

我以为打包为war为例说明。

1.设定springboot项目的启动类，在pom.xml中加入以下内容

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.DemoApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
        <!-- <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <filtering>false</filtering>
            </resource>

            <resource>
                <directory>src/main/webapp</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources> -->
    </build>

2.进入springboot项目的pom.xml所在的目录

执行命令 mvn clean package ，项目会被打包到同级的target文件夹中。

$ mvn clean package

 3.进入刚刚打好的war包同级目录，执行命令   java -jar myspringboot-xxxxx.war
