otter4.2.15 同步json报错

数据库版本5.7.20 源库表为utf8格式 目标库表为utf8mb4 同步时候报错

源库json数据为 id: 20237375 result: {"result": [{"success": true, "desc": "成功"}], "success": true}

现在源表是utf8mb4,目标也是utfmb4类型的,result是json类型的,我仍然没有解决掉 我改了报错里的信息，原始信息如下 EventColumn[index=21,columnType=1,columnName=result,columnValue=,isNull=true,isKey=false,isUpdate=true] 其实数据里是可以查到这个值的，非常奇怪

我自己测试了一下 包含null这样的数据在做同步的时候是会报错的 {"shop": "15802"，"condition_total": null} 如果是下面这样的形式就不会报错了 {"shop": "15802"，"condition_total": "null"}

还有一种情况，原始的值本来就是个null eventColumn类的isNull方法判断出来并不是一个null对象，而是解析出来一个NULL，并不是一个json字段，这时候也会报错

我修改对于json类型取值时候的方法 如果是有key但是值为null，我们就把这个key的值设置为“”空字符串 如果本身列的值就是null或者不是以“{”开头及“}”结尾的，我们就把这个值设置为“{}”

以上所述，希望对以后遇到此类问题的人有所帮助
