    public String testLogWrite(TestLogInDTO testLogInDTO) {
        log.info("名字是：{}，测试日志打印入参：{}", testLogInDTO.getName(), JSON.toJSONString(testLogInDTO));

        log.info("测试日志打印出参：{}", stringBuilder.toString());
        return stringBuilder.toString();
    }

log.info("测试日志打印入参是：" + JSON.toJSONString(testLogInDTO));
