java 字符串的json格式数据转换成Map集合

1.如何是maven项目的在pom.xml加入

dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20160810</version>
</dependency>

依赖.如不是自行下载jar包

 

2.示例如下

public static void main(String[] args) {
        
        String detail="{\"result\":0,\"msg\":\"成功\",\"info\":{\"saleUnit\":\"\",\"weight\":\"0.04\"}}";
        
     6         
        JSONObject json=new JSONObject(detail);
        Map<String,Object> map=new HashMap<String, Object>();
        Iterator it = json.keys();
        while (it.hasNext()) {  
           String key = (String) it.next();  
           Object value = json.get(key);  
           map.put(key, value);
        }
        System.out.println(map.get("info"));
    }
