SpringBoot項目打包成jar並運行

1、確保SpringBoot項目在IDE中可以正常運行

2、在pom.xml中添加如下配置

<build>
    <!--這里寫上打成jar包的名稱-->
    <finalName>springboot_quick_1</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <!--這里寫上main方法所在類的路徑-->
                <mainClass>com.lcy.Application</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

為防止部分網友弄錯配置，如下展示添加配置后pom.xml文件中的所有內容

<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">

    <artifactId>springboot_quick_1</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>
    
    <parent>

        <version>2.1.0.RELEASE</version>
    </parent>
    
    <dependencies>
        <dependency>

        </dependency>
    </dependencies>

<build>
    <!--這里寫上打成jar包的名稱-->
    <finalName>springboot_quick_1</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <!--這里寫上main方法所在類的路徑-->
                <mainClass>com.lcy.Application</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
</project>

3、進入項目所在文件夾內，執行命令：mvn install

4、等第3步執行完成，界面顯示BUILD SUCCESS后，再執行命令：mvn package spring-boot:repackage

5、等第4步執行完成，界面顯示BUILD SUCCESS后，進入項目的target文件夾內，可以找到jar

 

 6、運行jar：java -jar springboot_quick_1.jar
