从命令行运行Spring Boot应用程序时出错

我使用Maven“mvn clean package”打包了一个spring引导服务，并且我成功地能够创建该jar。但是，当我使用下面的命令从命令行运行它：“Java的罐子\目标\ noentenimnininc-0.0.1-SNAPSHOT.jar”我得到下面的错误::从命令行运行Spring Boot应用程序时出错

no main manifest attribute, in noentenimnininc-0.0.1-SNAPSHOT.jar

这是主类

@SpringBootApplication 
@Import({SecurityConfig.class }) 
public class NoEnTenimNiCincApplication implements CommandLineRunner { 

    /** The application logger */ 
    private static final Logger LOG = LoggerFactory.getLogger(NoEnTenimNiCincApplication.class); 

    @Autowired 
    private UserService userService; 

    @Value("${webmaster.username}") 
    private String webmasterUsername; 

    @Value("${webmaster.password}") 
    private String webmasterPassword; 

    @Value("${webmaster.email}") 
    private String webmasterEmail; 

    public static void main(String[] args) { 
     SpringApplication.run(NoEnTenimNiCincApplication.class, args); 
    } 


    @Override 
    public void run(String... args) throws Exception { 

     User user = UserUtils.createBasicUser(webmasterUsername, webmasterEmail); 
     user.setPassword(webmasterPassword); 
     Set<UserRole> userRoles = new HashSet<>(); 
     userRoles.add(new UserRole(user, new Role(RolesEnum.ADMIN))); 
     LOG.debug("Creating user with username {}", user.getUsername()); 
     userService.createUser(user, PlansEnum.PRO, userRoles); 
     LOG.info("User {} created", user.getUsername()); 
    }  
}

，一切工作正常，从Eclipse中运行类 - >运行方式 - > Java的应用项目

这里该模块的pom.xml中：

是否配置弹簧引导Maven的插件生成相应的可执行的JAR – Tome

检查这个帖子http://stackoverflow.com/questions/9689793/cant-execute-jar-file-no-main-manifest-attribute –

只需添加到您的pom.xml，使春季启动Maven插件重新打包的JAR成可执行一个：

<build> 
     <plugins> 
      <plugin> 
       <groupId>org.springframework.boot</groupId> 
       <artifactId>spring-boot-maven-plugin</artifactId> 
      </plugin> 
     </plugins> 
    </build>
