json zhuan map

将JSON对象转为Map对象可以使用阿里巴巴封装的FastJSON来实现。你可以使用JSON类的parseObject方法来解析JSON字符串并转换为Map对象，或者使用JSONObject类的parse方法来实现。具体代码如下：

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;

// 将JSON字符串解析为Map对象
String jsonString = "{\"key1\":\"value1\", \"key2\":\"value2\"}";
Map<String, Object> map = JSON.parseObject(jsonString, new TypeReference<Map<String, Object>>() {});

// 遍历Map对象并输出键值对
for (Map.Entry<String, Object> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " " + entry.getValue());
}

这段代码可以将JSON字符串`{"key1":"value1", "key2":"value2"}`转换为Map对象，并通过遍历Map对象将键值对输出到控制台。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
