SpringBoot项目打包成jar并运行

1、确保SpringBoot项目在IDE中可以正常运行

2、在pom.xml中添加如下配置

<build>
    <!--这里写上打成jar包的名称-->
    <finalName>springboot_quick_1</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <!--这里写上main方法所在类的路径-->
                <mainClass>com.lcy.Application</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

为防止部分网友弄错配置，如下展示添加配置后pom.xml文件中的所有内容

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <packaging>jar</packaging>

    </parent>

<build>
    <!--这里写上打成jar包的名称-->
    <finalName>springboot_quick_1</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <!--这里写上main方法所在类的路径-->
                <mainClass>com.lcy.Application</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
</project>

3、进入项目所在文件夹内，执行命令：mvn install

4、等第3步执行完成，界面显示BUILD SUCCESS后，再执行命令：mvn package spring-boot:repackage

5、等第4步执行完成，界面显示BUILD SUCCESS后，进入项目的target文件夹内，可以找到jar

 6、运行jar：java -jar springboot_quick_1.jar
