java 中org.json的用法
一,工程pom文件中新增依赖,参考http://mvnrepository.com/artifact/org.json/json/20160212
<dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20160212</version> </dependency>
二、用到的部分代码,用Json 字符串生成json对象,再从中获取需要的字段
/* 解析消息 */ String clientMsg = tuple.getStringByField("clientInfo"); /* covert string to json object */ JSONObject clientMsgObject = new JSONObject(clientMsg); String acSNStr = clientMsgObject.getString("acSN"); String clientMacStr = clientMsgObject.getString("clientMAC"); String onLineTimeStr = clientMsgObject.getString("onLineTime");
