json

问题 I have a column which has Json string records. I want to parse the json and fetch the value of a particular key from within the select statement. Sample JSON {"kofaxDocId":"8ae16f46-c68f-11e5-8105-0e15fb39b661","systemDocType":"Loan Application","requestId":"c770a940-b9f3-4c41-aee6-3e08c1470ec6","docType":"Loan Application","confidence":0.6499999761581421,"engineType":"kofax","completionStatus":"Suggested"} I want my select query to fetch only the value of the key "confidence". I tried using

问题 I have this which works to declare a JSON string in a bash script: local my_var="foobar" local json=`cat <<EOF {"quicklock":"${my_var}"} EOF` The above heredoc works, but I can't seem to format it any other way, it literally has to look exactly like that lol. Is there any way to get the command to be on one line, something like this: local json=`cat <<EOF{"quicklock":"${my_var}"}EOF` that would be so much nicer, but doesn't seem to take, obviously simply because that's not how EOF works I

问题 I wish to have a custom GSON deserializer such that whenever it is deserializing a JSON object (i.e. anything within curly brackets { ... } ), it will look for a $type node and deserialize using its inbuilt deserializing capability to that type. If no $type object is found, it just does what it normal does. So for example, I would want this to work: { "$type": "my.package.CustomMessage" "payload" : { "$type": "my.package.PayloadMessage", "key": "value" } } public class CustomMessage { public

问题 I use Spring MVC 3.2.4. I have a controller method that receives data from an HTML form.

问题 The program below generates different JSON when run in a .NET Core project vs a .NET Framework app. Code class Program { internal static readonly MediaTypeFormatter DefaultFormatter = new JsonMediaTypeFormatter { UseDataContractJsonSerializer = false, SerializerSettings = { NullValueHandling = NullValueHandling.Ignore, DateTimeZoneHandling = DateTimeZoneHandling.Utc, DateFormatHandling = DateFormatHandling.IsoDateFormat } }; private static DataTable BuildTestDataTable() { var testDataTable =

问题 I have a json file with same key but different values as follows, { "domains" : { "A" : { "name" : "a", "type" : "a1" }, "B" :{ "name" : "r", "type" : "g1" }, "A" : { "name" : "b", "type" : "b1" } } } which is coming from external system . How to convert the json to java map object and access the different values of the key: A I am using something like below, map = mapper.readValue(json, new TypeReference<HashMap<String,String>>(){}); which returns a map with unique keys. But I need a map
