使用属性文件中的值初始化枚举中的常量

constant1=value1
constant2=value2
constant3=value3

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;

public class EnumExample {
    public enum MyEnum {
        CONSTANT1,
        CONSTANT2,
        CONSTANT3
    }

    public static void main(String[] args) {
        Properties properties = new Properties();
        try {
            FileInputStream fileInputStream = new FileInputStream("config.properties");
            properties.load(fileInputStream);
            fileInputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

        MyEnum constant1 = MyEnum.valueOf(properties.getProperty("constant1"));
        MyEnum constant2 = MyEnum.valueOf(properties.getProperty("constant2"));
        MyEnum constant3 = MyEnum.valueOf(properties.getProperty("constant3"));

        System.out.println(constant1);
        System.out.println(constant2);
        System.out.println(constant3);
    }
}
