json字符串转数组转对象

举例子，现在有json字符串[{"subsidy":"23","subFlag":"0"}]，想将它转为对象，比如转为map，要怎么实现呢，下面写一种方法参考

public List<Object> getDataByCondition1() {                    List<Object> mapList = null;                String jsonStr = "+[{"subsidy":"23","subFlag":"0"}]+";                if(!Strings.isNullOrEmpty(jsonStr)){                    JSONArray jsonArr = JSONArray.fromObject(jsonStr);                    String classStr = configData.getDataclass();                    if(Strings.isNullOrEmpty(classStr)){                        classStr = "java.util.Map";                    }                    Class clazz = Class.forName(classStr);                    mapList = (List)JSONArray.toCollection(jsonArr,clazz);                }         return mapList;<pre name="code" class="java">    }
