Spring Boot Jackson map JSON response from 3rd party API to custom Object

Issue

I want to create a Java class out of a json response I get from a third party API which I have already managed to to with using the ObjectMapper. However, in this specific case, the JSON response has no keys so I dont know how I can map this into an Object, basically how should I use @JsonProperty annotation if the json response looks like this

[
[
1499040000000,      // Kline open time
"0.01634790",       // Open price
"0.80000000",       // High price
"0.01575800",       // Low price
"0.01577100",       // Close price
"148976.11427815",  // Volume
1499644799999,      // Kline Close time
"2434.19055334",    // Quote asset volume
308,                // Number of trades
"1756.87402397",    // Taker buy base asset volume
"28.46694368",      // Taker buy quote asset volume
"0"                 // Unused field, ignore.
]
]

Solution

You want to use:

@JsonFormat(shape = JsonFormat.Shape.ARRAY)
@JsonPropertyOrder({ "foo", "bar" })
public class FooBar {
  public String foo;
  public String bar;
}
