如何使用RestTemplate发布bean列表，但bean必须是字节数组？

public class MyBean {
    private byte[] data;

    // 省略构造函数、getter和setter方法
}

RestTemplate restTemplate = new RestTemplate();

// 创建一个包含字节数组的MyBean对象
MyBean myBean = new MyBean();
myBean.setData(yourByteArray);

// 创建HttpHeaders对象，并设置Content-Type为application/json
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);

// 创建HttpEntity对象，将MyBean对象和HttpHeaders对象作为参数传入
HttpEntity<MyBean> requestEntity = new HttpEntity<>(myBean, headers);

// 发送POST请求，并获取响应结果
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);

List<MyBean> beanList = new ArrayList<>();

// 添加多个MyBean对象到列表中
beanList.add(myBean1);
beanList.add(myBean2);
// ...

// 创建HttpEntity对象，将beanList和HttpHeaders对象作为参数传入
HttpEntity<List<MyBean>> requestEntity = new HttpEntity<>(beanList, headers);

// 发送POST请求，并获取响应结果
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);
