1.需要库：

commons-beanutils-1.7.0.jar

commons-collections-3.1.jar

commons-lang-2.1.jar

commons-logging-1.1.3.jar

ezmorph-1.0.2.jar

json-lib-2.4-jdk15.jar

2.转换方法：

　　//对象转json　 sqlModel model = new sqlModel(); model.setAge(18); model.setHeight(188.0); model.setName("张三"); String jsonStr = null; try { JSONObject jsonObject = JSONObject.fromObject(model); jsonStr = jsonObject.toString(); System.out.println(jsonStr); } catch (Exception e) { System.out.println("数组转json失败"); }

结果：

{"age":18,"height":188,"name":"张三"} //数组转jsonString jsonStr = null; try { JSONArray jsonObject = JSONArray.fromObject(myNameList); jsonStr = jsonObject.toString(); System.out.println(jsonStr); } catch (Exception e) { System.out.println("数组转json失败"); } 结果：["aaaa","bbbb","cccc","cc","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl"]
