如何从文件加载Java枚举元素的值

Question

我有一个Java Enum:

public enum CodeType {
  BRONZE("00001BP", "BAP"),
  SILVER("00002SL", "SAP"),
  GOLD("00003GL", "GAP"),
  MOBILE("00004MB", "TCM"),
  SOCIAL("00005SM", "ASM"),
  WEB_PRESENCE("00006WP", "GLO"),
  EMAIL_MARKETING("00007EM", "PEM"),
  CUSTOM_DIAMOND("00008CD", "PCS"),
  CONSUMER_PORTAL("00009CP", "CPS");

  private String code;
  private String key;

  CodeType(String code, String key) {
    this.code = code;
    this.key = key;
  }

  ...
}

如你所见,我有九个元素,每个元素都有两个值.我的问题是如何从属性或xml等文件中加载这些元素的值？我的意思是:

BRONZE(isLoadedFromFile, isLoadedFromFile),
...
CONSUMER_PORTAL(isLoadedFromFile, isLoadedFromFile);

非常感谢.

试试这样的东西......

public enum EnumTest {

    BRONZE, SILVER;

    public String getProperty(String keyOrCode) {
        Properties prop = new Properties();
        try {
            prop.load(new FileInputStream("E:\\EnumMapper.properties"));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return prop.getProperty(this.name() + "." + keyOrCode);
    }

    public String getCode() {
        return getProperty("CODE");
    }

    public String getKey() {
        return getProperty("KEY");
    }

    public static void main(String[] args) {
        System.out.println(EnumTest.BRONZE.getCode());
        System.out.println(EnumTest.BRONZE.getKey());

    }

}

EnumMapper.properties包含的位置

BRONZE.CODE=00001BP
BRONZE.KEY=BAP
SILVER.CODE=00002SL
SILVER.KEY=SAP

只是想分享一些可能性..
