I get a JSONObject
from the client and I want to convert it to a Map
in Java Spring-Boot. Does anyone know a good approach with my data structure?
Json Object:
FilterObject: {
"firstName":
{"filterType":"text","type":"contains","filter":"emma"},...
}
Map to:
Map<String, ColumnFilter> filterMap;
public class ColumnFilter {
private String filterType;
private String type;
private String filter;
}
CodePudding user response:
You can use this code snippet:
String columnFilterJson = "{\"firstName\":{\"filterType\":\"text\",\"type\":\"contains\",\"filter\":\"emma\"}}";
ObjectMapper objectMapper = new ObjectMapper();
HashMap<String, ColumnFilter> columnFilterMap = objectMapper.readValue(columnFilterJson, new TypeReference<HashMap<String, ColumnFilter>>() {});
Then with considering your ColumnFilter
class has toString()
method you can check result:
for (Map.Entry<String, ColumnFilter> entry: columnFilterMap.entrySet()) {
String key = entry.getKey();
ColumnFilter value = entry.getValue();
System.out.println(key);
System.out.println(value);
}
