如何将包含字符串键和浮点值的Json树转换为Map

import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;

import java.io.IOException;
import java.util.Map;

public class JsonToMapConverter {
    public static void main(String[] args) {
        String json = "{\"key1\": 1.1, \"key2\": 2.2, \"key3\": 3.3}";

        ObjectMapper objectMapper = new ObjectMapper();
        try {
            // 将JSON字符串转换为Map<String, Float>
            Map<String, Float> map = objectMapper.readValue(json, new TypeReference<Map<String, Float>>() {});

            // 打印转换后的Map
            map.forEach((key, value) -> System.out.println(key + ": " + value));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
