JSON.config(JSONWriter.Feature.WriteMapNullValue);
大量数据转换时
zymzdzblPo.setContent(content.toJSONString());
jvm直接crash

[wenshao]

这个没看到fastjson2的堆栈啊

[lion000]

昨天在找问题，提的比较急
情况是这样的，用上面的代码，做javabean转json再转json字符串，javabean属性为空时，默认会丢失key，所以添加JSON.config(JSONWriter.Feature.WriteMapNullValue);全局配置，调用方式时设置，效果一样
添加之后，大概几万的数据量，做批量转换时，jvm崩溃，详细的堆栈如下，还有一些堆栈日志，需要的话，可以提供
