android okhttpclient多次调用同一方法导致socket is closed

多次通过okhttpclient从后端加载图片，导致socket is closed。有什么解决方吗码？保持长连接不行

public Bitmap getImageBitMap(String imgUrl) throws IOException {
    Bitmap bitmap;
    OkHttpClient okHttpClient = new OkHttpClient();
    Request request = new Request.Builder()
            .url(imgUrl)
            .build();
    Response response = okHttpClient.newCall(request).execute();
    byte[] bytes = Objects.requireNonNull(response.body()).bytes();
    bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
    return bitmap;
}

我试了下你这代码多次下载没问题啊。是不是后端图片下载接口有问题？

后端获取图片的代码

@Configuration
public class WebMvcConfigure extends WebMvcConfigurationSupport {
    private static final Logger logger = LoggerFactory.getLogger(WebMvcConfigure.class);
    @Value("${uploadFilePath}")
    private String uploadFilePath;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        logger.info(uploadFilePath);

        //和页面有关的静态目录都放在项目的static目录下
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
        //上传的图片路径
        registry.addResourceHandler("/uploaded/**").addResourceLocations("file:" + uploadFilePath);

    }
}

貌似不是okhttpclient的问题，现在已经能够正常运行了

我没改okhttpcient以及后端代码。我也不知道，后来就好了。
为spinner绑定了onItemSelected，然后再调用线程。

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                switch (i) {
                    case 0:
                        Thread thread1 = new Thread(runnable1);
                        thread1.start();
                        break;
                    case 1:
                        Thread thread2 = new Thread(runnable2);
                        thread2.start();
                        break;
                    case 2:
//                        暂时不支持
                        break;
                    case 3:
                        Thread thread4 = new Thread(runnable4);
                        thread4.start();
                        break;
                }
            }
            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {
            }
        });

然后在线程中，调用了okhttpclient

Runnable runnable1 = new Runnable() {
        @Override
        public void run() {
            productOkHttp http = new productOkHttp();
            try {
                List<product> products = http.getProduct();
                handleData(products,http);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
    };
