线程不是都实现Runnable或者继承Thread吗，这里面的线程是怎么启动的

Question

@Component
public class WorkerService {
private static final Logger logger = LoggerFactory
.getLogger(WorkerService.class);
@Autowired
private QueueService queueService;
@Autowired
private NoticeClient noticeClient;
@Value("${file.store.path}")
private String fileStorePath;
public final int BUFSIZE = 1024 * 8;

@PostConstruct
public void init() {
    this.processMerge();
    this.processNotice();
}

/**
 * 启动发送上传完成通知的线程
 */
private void processMerge() {
    queueService.rightPop("merge", new Worker() {
        @Override
        public void process(final String content) {
            String[] array = content.split(",");
            String name = array[0];
            long size = Long.valueOf(array[1]);
            File iso = new File(fileStorePath, name + ".iso");
            if (!iso.exists()) {
                long block = size / 1048576 + (size % 1048576 > 0 ? 1 : 0);
                List<File> fileList = new ArrayList<>();
                for (long i = 0; i < block; i++) {
                    fileList.add(new File(fileStorePath + "/" + name, String.valueOf(i)));
                }
                mergeFiles(iso,fileList);
            }
            if(name.startsWith("97")) {
                queueService.leftPush("state", content);
            }
            if(iso.exists()){
                File folder = new File(fileStorePath, name);
                try {
                    FileUtils.deleteDirectory(folder);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    });
}

你看一下QueueSerivce所属类的源代码呗，这个只是匿名内部类，有点像是其他语言中的闭包，把你要完成的逻辑传出去，程序会在适当的地方调用
