使用JSON将JSON转换为Map<String、String>

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonToMapExample {
    public static void main(String[] args) {
        String json = "{\"key1\":\"value1\",\"key2\":\"value2\",\"key3\":\"value3\"}";

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            Map<String, String> map = objectMapper.readValue(json, new TypeReference<Map<String, String>>() {});

            // 输出转换后的Map
            for (Map.Entry<String, String> entry : map.entrySet()) {
                System.out.println(entry.getKey() + ": " + entry.getValue());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
