我正在尝试找到在Java中读取YAML文件的最佳方法。我不确定哪个解析器是最好的,但目前我读取动态的解决方案(如果用户想向文件添加更多内容,下次程序加载时)是一系列 for 循环,在 ArrayLists 和哈希映射之间转换并解析原始字符串。
前任:
HashMap<Object, Object> perWaveHashMap = (HashMap)waveConfiguration.getList("waves").get(wave); //wave-1
for(Object mobObject : perWaveHashMap.values()){
ArrayList<Object> mobObjectArrayList = (ArrayList) mobObject;
for(Object mob : mobObjectArrayList){
HashMap<Object, Object> mobHashMap = (HashMap)mob;
String mobNameString = null;
for(Object mobName : mobHashMap.keySet()){
mobNameString = mobName.toString();
}
for(Object mobAttribute : mobHashMap.values()){
HashMap<Object, Object> attributesToGive = (HashMap)mobAttribute;
final ArrayList<Object> attributeList = new ArrayList<>();
for(Object attribute : attributesToGive.values()){
attributeList.add(attribute);
}
assert mobNameString != null;
final String finalMobNameString = mobNameString;
System.out.println("Final Mob Name String: " + finalMobNameString);
if(finalMobNameString.equalsIgnoreCase("vintr")){
Mobs.isSpecialBossWave =true;
new Vintr();
} else {
if (attributeList.size() == 1) {
Mobs.addMobs((int) attributeList.get(0), EntityType.valueOf(finalMobNameString.toUpperCase()));
} else if (attributeList.size() == 2) {
Mobs.addMobs((int) attributeList.get(0), EntityType.valueOf(finalMobNameString.toUpperCase()), (int) attributeList.get(1));
} else if (attributeList.size() == 3) {
Mobs.addMobs((int) attributeList.get(0), EntityType.valueOf(finalMobNameString.toUpperCase()), (int) attributeList.get(1), (boolean) attributeList.get(2));
} else if (attributeList.size() == 4) {
Mobs.addMobs((int) attributeList.get(0), EntityType.valueOf(finalMobNameString.toUpperCase()), (int) attributeList.get(1), (boolean) attributeList.get(2), (boolean) attributeList.get(3));
} else if (attributeList.size() == 5) {
Mobs.addMobs((int) attributeList.get(0), EntityType.valueOf(finalMobNameString.toUpperCase()), (int) attributeList.get(1), (boolean) attributeList.get(2), (boolean) attributeList.get(3), (boolean) attributeList.get(4));
} else if (attributeList.size() == 6) {
Mobs.addMobs((int) attributeList.get(0), EntityType.valueOf(finalMobNameString.toUpperCase()), (int) attributeList.get(1), (boolean) attributeList.get(2), (boolean) attributeList.get(3), (boolean) attributeList.get(4), (boolean) attributeList.get(5));
}
}
}
}
}
基本上,YML 文件如下所示:
waves:
- 1:
- zombie:
amount: 1
modifier: 2
boss: false
beeline: false
- 1:
- spider:
amount: 12
modifier: 2
boss: false
beeline: false
hunter: true
-2 :
- mobname:
-options
我的代码现在的方式允许我添加任意数量的"波",以及我想要的每波中任意数量的生物。我发现我编写代码的方式非常丑陋且难以使用,并且正在寻找解决此问题的更好方法。
欢迎任何帮助!
谢谢
您可以使用 snakeyaml 将 yaml 文件读入 POJO。
File configFile = new File(configFilename);
FileInputStream fis = new FileInputStream(configFile);
Yaml yaml = new Yaml(new Constructor(Config.class));
Config config = yaml.loadAs(fis, Config.class);
您的 Config 类可以如下所示:
public class Config {
List<Wave> waves;
public List<Wave> getWaves() {
return waves;
}
}
// similarly define other classes for the Wave etc...
