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json
String 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"]
