哪个版本？给个 testcase?

2.0.45 参数就是上的json
但是这个不是每次都能复现 我本地没有出现过 在国产环境有时间会出现 上面的json就是出现时的前台传的信息 @RequestMapping("/saveData") public void saveData(@RequestBody Map param) throws Exception { String s = JSONObject.from(param).toString(); System.out.println(s); }

奇怪了，我是在阿里云的倚天710 ARM机器上测试过没问题的，鲲鹏不知道是什么架构，没有环境

1195952223 commented 9 months ago

使用JSON.toJSONString(param, JSONWriter.Feature.FieldBased, JSONWriter.Feature.WriteNullStringAsEmpty);代替了 目前没有在报错了 在观察观察

2502 看下我提交的这个bug，我也是鲲鹏服务器上，不是每次必现

wenshao commented 6 months ago

@luckytao 这个问题在linux aarch64 jdk8下会偶发，我也没找到原因，现在的做法是JDK8就换一种实现。

https://oss.sonatype.org/content/repositories/snapshots/com/alibaba/fastjson2/fastjson2/2.0.50-SNAPSHOT/ 问题已修复，请帮忙用2.0.50-SNAPSHOT版本验证，2.0.50版本预计在5月12日前发布

最新版本的快照版本已经在多种aarch64架构的服务器上通过JDK8/11/17测试，包括：

阿里云倚天710 华为云鲲鹏服务 Amazon EC2 C7g (Arm-based AWS Graviton3) Orange Pi5 Plus RK3588 Orange Pi Aipro (昇腾)
