springboot 项目pom配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.docker</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><name>demo</name><description>demo</description><packaging>jar</packaging><properties><java.version>1.8</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><spring-boot.version>2.2.3.RELEASE</spring-boot.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>${spring-boot.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration><source>1.8</source><target>1.8</target><encoding>UTF-8</encoding></configuration></plugin><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>${spring-boot.version}</version><configuration><mainClass>com.docker.demo.DemoApplication</mainClass><skip>false</skip></configuration></plugin></plugins></build></project>

执行：java -jar demo-0.0.1-SNAPSHOT.jar

提示：demo-0.0.1-SNAPSHOT.jar中没有主清单属性

解压：demo-0.0.1-SNAPSHOT.jar
打开 demo-0.0.1-SNAPSHOT\META-INF\MANIFEST.MF 文件，内容如下

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Built-By: Administrator
Created-By: Apache Maven 3.2.5
Build-Jdk: 1.8.0_261

缺少了启动类Start-Class: com.docker.demo.DemoApplication

解决方法：
1.修改spring-boot-maven-plugin插件配置增加repackage

<plugin>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-maven-plugin</artifactId>
   <version>${spring-boot.version}</version>
   <configuration>
       <mainClass>com.docker.demo.DemoApplication</mainClass>
       <skip>false</skip>
   </configuration>
<executions>
   <execution>
       <id>repackage</id>
       <goals>
           <goal>repackage</goal>
       </goals>
   </execution>
</executions>
</plugin>

2. IDEA 执行 mvn clean mvn install

3. 执行 java -jar demo-0.0.1-SNAPSHOT.jar 启动成功

4.打开 demo-0.0.1-SNAPSHOT\META-INF\MANIFEST.MF 文件，内容如下

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Built-By: Administrator
Start-Class: com.docker.demo.DemoApplication
Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/
Spring-Boot-Version: 2.2.3.RELEASE
Created-By: Apache Maven 3.2.5

Main-Class: org.springframework.boot.loader.JarLauncher
