JAVA对象、数组转JSON

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"]
