Question

我目前正致力于将所有House对象数据保存到文件中。当前我通过.txt加载它并使用BufferedWriter中的write函数保存它。我相信我可以使用JSON来解析我的所有HouseObject数据，但我不知道我该怎么做。我对这一切都很陌生。

这是我的加载/保存文件：

package com.darkasylum.rs2.content.house;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.HashMap;

import com.darkasylum.rs2.entity.object.GameObject;
import com.darkasylum.rs2.entity.player.Player;

public class HouseUtils {
	// Map of all houses.
	public static HashMap<Integer, HouseObject> ALL_HOUSES = new HashMap<Integer, HouseObject>();

	public static int currentlyLoaded = 0;

	// load all hosues
	public static void load(Player player) {
	FileReader fileReader = null;
	BufferedReader reader = null;
	try {

		if (!ALL_HOUSES.containsValue(player.getHouse())) {
			fileReader = new FileReader(new File("./data/houses/" + player.getUsername() + ".txt"));
			reader = new BufferedReader(fileReader);

			ALL_HOUSES.put(currentlyLoaded, player.getHouse());
			player.player_house_key = currentlyLoaded;
			currentlyLoaded++;

			try {
				reader.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		} else {
			System.out.println("Already in map");
		}
	} catch (FileNotFoundException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	}

	// save/input new house for new player
	public static void save(Player player) {
	BufferedWriter writeHouse = null;
	File playerfile = new File("./data/houses/" + player.getUsername() + ".txt");

	if (!playerfile.exists()) {
		try {
			playerfile.createNewFile();

		} catch (IOException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
	}

	try {
		writeHouse = new BufferedWriter(new FileWriter(playerfile));
		writeHouse.write("Owner Name:" + player.getHouse().getOwner_name() + "\n");
		writeHouse.write("House Name:" + player.getHouse().getHouse_name() + "\n");
		writeHouse.write("Personal Objects:\n");
		player.getHouse();
		
		for (int i = 0; i < player.getHouse().myPersonalObjects.size(); i++) {
			writeHouse.write("\t" + player.getHouse().myPersonalObjects.get(i).getId() + ", " + player.getHouse().myPersonalObjects.get(i).getLocation().getX() + ", " + player.getHouse().myPersonalObjects.get(i).getLocation().getY() + ", " + player.getHouse().myPersonalObjects.get(i).getType() + ", " + player.getHouse().myPersonalObjects.get(i).getType() + "\n");
		}

		writeHouse.close();
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

	}
}

这是我的HouseObject

package com.darkasylum.rs2.content.house;

import java.util.HashMap;

import com.darkasylum.rs2.entity.object.GameObject;

public class HouseObject {

private String house_name;
private String owner_name;
public HashMap<Integer, GameObject> myPersonalObjects = new HashMap<Integer, GameObject>();

public String getOwner_name() {
	return owner_name;
}

public void setOwner_name(String owner_name) {
	this.owner_name = owner_name;
}

public String getHouse_name() {
	return house_name;
}

public void setHouse_name(String house_name) {
	this.house_name = house_name;
}

public HouseObject() {
	this.house_name = "N/A";
	this.owner_name = "N/A";
}

public HouseObject(String house_name, String owner_name, GameObject object) {
	this.house_name = house_name;
	this.owner_name = owner_name;
	add_object(object);
}
public void add_object(GameObject objectToAdd) {
	myPersonalObjects.put(myPersonalObjects.size(), objectToAdd);
}
}

我真的想要一些有关改进的提示。我知道我有一些格式错误，比如我的一些命名惯例，但那些是我的一些习惯，我真的不想改善个人喜好。

您可以使用JSON marshaller。您可以查看oracle tutorial以及this SO Q＆amp; A.
