内部Json Blob应转换为Map<String、String>

import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonBlobConverter {
    public static Map<String, String> convertJsonBlob(String jsonBlob) {
        ObjectMapper objectMapper = new ObjectMapper();
        try {
            return objectMapper.readValue(jsonBlob, new TypeReference<Map<String, String>>() {});
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}

String jsonBlob = "{\"key1\": \"value1\", \"key2\": \"value2\"}";
Map<String, String> map = JsonBlobConverter.convertJsonBlob(jsonBlob);
System.out.println(map.get("key1"));  // 输出：value1
System.out.println(map.get("key2"));  // 输出：value2
