只需在项目的pom.xml中加入下面插件

<build>

    <plugins>

        <plugin>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-maven-plugin </artifactId>

        </plugin>

        <plugin>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-maven-plugin</artifactId>

            <executions>

                <execution>

                    <goals>

                        <goal>repackage</goal>

                    </goals>

                </execution>

            </executions>

        </plugin>

    </plugins>

</build>

然后执行mvn package，就可以在target文件夹下找到生成的jar包

然后运行 java -jar ****.jar即可
