我需要在Java中编写解析JSON数组的代码。

请给我:

1) Java代码 2)正确导入相应的jar库

3) Url(链接)下载JAR

Answer 1

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;


public static <T> T jsonStringToObject(String jsonString , Class<T> objectClass){
            ObjectMapper mapper = new ObjectMapper();
            mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
            T t=null;
            try {
                  t = mapper.readValue(jsonString, objectClass);
            } catch (IOException e) {
                e.printStackTrace();
            }
            return t;
        }

Person person=jsonStringToObject(jsonString, Person.class);

//注意person调用具有与json相同的属性

从这里下载jackson -core jarhttp://www.java2s.com/Code/Jar/c/Downloadcomfasterxmljacksoncorejar.htm
