JsonData.fromJson(String.valueOf(System.currentTimeMillis())) 出现问题
JsonData.fromJson(“now”)出现问题
今天在做时间衰减函数的时候发现一个问题，搞了我好久没有解决，后面查看了官网文档才发现，这部分代码目前仅支持半手动挡或者手动挡的实现，还没有完全实现自动挡呢，这就让我非常苦恼，没得办法，只能使用半原生的方式去解决JsonData.from解决日期的问题。

这段代码会出现日期解析的问题，不能使用这种方式解决
java">.placement(placementBuilder -> placementBuilder
.origin(JsonData.fromJson(String.valueOf(System.currentTimeMillis())))
.offset(JsonData.fromJson("30d"))
.scale(JsonData.fromJson("9000d"))
.decay(0.5)
)
如果使用JsonData.fromJson(“now”)同样也会报错，只能改成这样子才能解决这个问题。

// 没办法，这部分代码目前只能挂手动档，自动挡处理不了，后面能挂自动挡了再修改过来就行

总结一下，es如果遇到问题，不要直接上去硬刚，看看能不能使用原生的方式解决。
