1.Maven项目使用JSON需要的依赖包
<!-- 引入json依赖 --><dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier></dependency><dependency> <groupId>commons-beanutils</groupId> <artifactId>commons-beanutils</artifactId> <version>1.7.0</version></dependency><dependency> <groupId>commons-collections</groupId> <artifactId>commons-collections</artifactId> <version>3.1</version></dependency><dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.5</version></dependency><dependency> <groupId>net.sf.ezmorph</groupId> <artifactId>ezmorph</artifactId> <version>1.0.3</version></dependency>2.遍历JSONArray
package cn.jm.action;import net.sf.json.JSONArray;import net.sf.json.JSONObject;/** * * @ClassName: Test * @Description: TODO * @Author Ming * @Date 2018年7月23日 下午8:41:28 * @Vesion 1.0 * */public class Test {public static void main(String[] args) {String str = "[{'status':'有效','name':'技限公司','code':'001'}," + "{'status':'无效','name':'有限公司','code':'005'}]";JSONArray json = JSONArray.fromObject(str); if(json.size()>0){ for(int i=0;i<json.size();i++){ JSONObject job = json.getJSONObject(i); // 遍历 jsonarray 数组，把每一个对象转成 json 对象 System.out.println(job.get("status")) ; // 得到 每个对象中的属性值 }}}}
