需要用到json相关的jar包，可以用库的，也可以用阿里的fastjson遍历json数组简单示例如下// 一个未转化的字符串 String str = "[{name:'a',value:'aa'},{name:'b',value:'bb'},{name:'c',value:'cc'},{name:'d',value:'dd'}]" ;   // 首先把字符串转成 JSONArray  对象 JSONArray json = JSONArray.fromObject(str ); if(json.size()>0){   for(int i=0;i<json.size();i++){  // 遍历 jsonarray 数组，把每一个对象转成 json 对象 JSONObject job = json.getJSONObject(i);  // 得到 每个对象中的属性值 System.out.println(job.get("name")+"=") ;     }
