我使用Maven“mvn clean package”打包了一个spring boot服务,我成功地创建了jar。但是当我使用以下命令从命令行运行它时:“java -jar \ target \ noentenimnininc-0.0.1-SNAPSHOT.jar”我收到以下错误::

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

这是主要的课程

@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());
    }    
}

从Eclipse运行该类的一切正常 - &gt;运行方式 - &gt; Java Appplication

这个模块的pom.xml:

只需将其添加到pom.xml,以便Spring Boot Maven插件将您的JAR重新打包成可执行文件:

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