JAVA對象、數組轉JSON

1.需要庫：

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.轉換方法：

　　//對象轉json
　 sqlModel model = new sqlModel();
   model.setAge(18);
   model.setHeight(188.0);
   model.setName("張三");
        
   String jsonStr = null;
   try {
      JSONObject jsonObject = JSONObject.fromObject(model);
      jsonStr = jsonObject.toString();
      System.out.println(jsonStr);
   } catch (Exception e) {
      System.out.println("數組轉json失敗");
   }

結果：

{"age":18,"height":188,"name":"張三"}

//數組轉json
String jsonStr = null;
try {
        JSONArray jsonObject = JSONArray.fromObject(myNameList);
        jsonStr = jsonObject.toString();
        System.out.println(jsonStr);
    } catch (Exception e) {
        System.out.println("數組轉json失敗");
    }
結果：["aaaa","bbbb","cccc","cc","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl","zzl"]
