spring使用哪个模型类作为请求映射方法的错误响应？

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @RequestMapping("/example")
    public ResponseEntity<String> handleRequest() {
        // 处理请求的逻辑
        // 如果发生错误
        if (errorCondition) {
            // 构建错误响应
            return ResponseEntity.status(HttpStatus.BAD_REQUEST).body("请求参数错误");
        }
        // 正常处理请求
        return ResponseEntity.ok("请求处理成功");
    }

    @ExceptionHandler(Exception.class)
    public ResponseEntity<String> handleException(Exception e) {
        // 处理全局异常
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("服务器内部错误");
    }
}
