TransferBatchRequest(appid=wx9efe3a0b52728900, out_batch_no=SUB202307131126162960002, batch_name=佣金提现, batch_remark=佣金提现, total_amount=50, total_num=1, transfer_scene_id=null, transfer_detail_list=[TransferDetail(out_detail_no=202307131126162960001, transfer_amount=50, transfer_remark=佣金提现, openid=oMvby5TmlWyMA1U1Yh4OkTtuSG5g, user_name=null)]) Java实体怎么转为{a:b,C:d}的格式

您可以使用Java中的JSON库将Java实体转换为{a:b,C:d}格式的字符串。以下是一个使用Jackson库的示例代码：

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) {
        TransferBatchRequest request = new TransferBatchRequest();
        request.setAppid("wx9efe3a0b52728900");
        request.setOutBatchNo("SUB202307131126162960002");
        request.setBatchName("佣金提现");
        request.setBatchRemark("佣金提现");
        request.setTotalAmount(50);
        request.setTotalNum(1);
        // 设置其他字段...

        ObjectMapper objectMapper = new ObjectMapper();
        try {
            String jsonString = objectMapper.writeValueAsString(request);
            System.out.println(jsonString);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }
}

在上面的示例中，我们使用了Jackson库的`ObjectMapper`类将`TransferBatchRequest`对象转换为JSON字符串。您需要根据实际情况设置其他字段。输出的字符串将符合{a:b,C:d}的格式。
