如何使用 flexjson 将 json 转换为 java Obj?

how to convert json to java Obj using flexjson?

是的。我的代码使用 flexjson 将 java obj 转换为 JSON。经测试没问题。但是我不知道如何将 JSON 转换为 java Obj。有人知道吗?提前感谢您的帮助。

        /**
         * convert java obj to json using flexjson 2.1.
         * 
         * @param obj
         * @return jsonStr
         */
    public static String bean2Json(Object obj) {
        JSONSerializer serilizer = new JSONSerializer();
        return serilizer.serialize(obj);
    }

     /**
      * convert json to java obj using flexjson 2.1.
      * 
      * @param jsonStr
      * @param objClass
      *
      * @return obj
      */
    public static <T> T json2Bean(String jsonStr, Class<T> objClass) {
      // TODO
    }
import flexjson.JSONDeserializer;
import flexjson.JSONSerializer;

public class DeserializerTest {
    public static void main(String[] args)
    {
        JSONSerializer serilizer = new JSONSerializer();
        Apple oneApple = new Apple(123);
        String appleString = serilizer.serialize(oneApple);

        // Convert Apple String to Apple object here
        Apple deserializedApple = new JSONDeserializer<Apple>().deserialize( appleString );
        System.out.println("AppleID: "+deserializedApple.appleID);
    }
}

public class Apple {
    public int appleID;

    public Apple(){}

    public Apple(int pAppleID){
        this.appleID=pAppleID;
    }
}

预期的输出应该是 AppleID: 123
