如何使用byte [] Java显示图片？Spring MVC

import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class ImageController {

    @RequestMapping(value = "/image", method = RequestMethod.GET)
    public ResponseEntity<byte[]> displayImage() {
        // 从数据库或其他地方获取图片数据，假设存储在imageData变量中

        // 设置响应头信息
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.IMAGE_JPEG);
        headers.setContentLength(imageData.length);

        // 创建ResponseEntity对象
        ResponseEntity<byte[]> responseEntity = new ResponseEntity<>(imageData, headers, HttpStatus.OK);

        return responseEntity;
    }
}
