Question

My Autowire可以在任何地方使用，但不能在我的线程上运行。我收到这个错误：

说明

threads.EnvironmentThread中的字段dockerService   需要一个'services.DockerService'类型的bean   无法找到。

动作：

考虑定义类型的bean   您的配置中的“services.DockerService”。

我的代码：

 @SpringBootApplication
public class IzyApplication implements CommandLineRunner{

@Autowired
private DockerService dockerService;

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


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

    // Call Threads
    ApplicationContext context = new AnnotationConfigApplicationContext(ThreadConfig.class);
    EnvironmentThread environmentThread = (EnvironmentThread) context.getBean("environmentThread");
    environmentThread.setName("Environment Thread");

    //Start Them
    environmentThread.start();
}

}

线程：运行EnvironmentThread environmentThread = (EnvironmentThread) context.getBean("environmentThread");

时抛出错误

@Component
@Scope("prototype")
public class EnvironmentThread extends Thread {

private static final Logger logger = Logger.getLogger(EnvironmentThread.class);

@Autowired
private DockerService dockerService;
@Autowired
private SettingsService settingsService;
@Autowired
private EnvironmentRepository environmentRepository;
@Autowired
private ReportService reportService;

@Override
public void run() {

}

threadconfig.vi可

@Configuration
@ComponentScan(basePackages = {"threads"})
public class ThreadConfig {

}

服务

@Service("dockerService")
public class DockerService {

private static Logger logger;
public DockerClient dockerClient;
@Autowired
private SettingsService settingsService;

// #####################  BUILD CONNECTION WITH DOCKER ####################################
@Singleton
public void buildDockerClient() {

    logger = Logger.getLogger(DockerService.class);

    try {
        //todo remove id
        Settings settings = settingsService.getSettings();
        DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder()
                .withDockerHost("tcp://" + settings.getDockerIP() + ":" + settings.getDockerPort())
                .withDockerConfig("/home/user/.docker/config.json")
                .build();

        dockerClient = DockerClientBuilder.getInstance(config).build();

    } catch (Exception e) {
        logger.error(e.getMessage(), e);
    }
  }

您正在使用ThreadConfig中指定@ComponentScan(basePackages = {"threads"})的设置创建应用程序上下文。

DockerService位于包services中。该应用程序上下文不知道它，因为您没有告诉它扫描该包。

Java中非常简单的线程
