配合JAVA后台，插件配置提交时报错Cannot construct instance of java.util.LinkedHashMap #146
Description
修改任意插件的json配置文件，保存，后台就会报错：
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `java.util.LinkedHashMap` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('{
"MiniApp": {
"appid": "xxxxx",
"secret": "xxxxx"
}
}')
原因是java后台中，接收参数config字段是
@ColumnDefine(comment = "配置", type = "json")
@Column(typeHandler = JacksonTypeHandler.class)
private Map<String, Object> config;而前端传递的config字段是json字符串
我自己的解决办法是在前端传递时：
{
...data,
config:JSON.parse(data.config)
}
