// Set via JVM args
// java -Dapp.name=MyApp -Dserver.port=8080 Main

// Or programmatically
System.setProperty("app.name", "MyApp");

Performance | 性能特性:

  • Time complexity: O(n) for loading - 时间复杂度: 加载为O(n)
  • Properties snapshot at creation - 创建时的属性快照

Security | 安全性:

  • Thread-safe: Yes - 线程安全: 是
  • Immutable snapshot - 不可变快照
