Util.toMap介绍

[英]Converts a Properties object to a Map<String, String>.

This is necessary because Properties is a dinosaur class. It ought to extend Map<String,String>, but instead extends Hashtable<Object,Object>.

Typical usage, to iterate over a Properties:
Properties properties; for (Map.Entry<String, String> entry = Util.toMap(properties).entrySet()) { println("key=" + entry.getKey() + ", value=" + entry.getValue()); }
[中]将属性对象转换为Map<String, String>。
这是必要的，因为属性是一个恐龙类。它应该扩展Map<String,String>，但应该扩展Hashtable<Object,Object>。
在属性上迭代的典型用法：
Properties properties; for (Map.Entry<String, String> entry = Util.toMap(properties).entrySet()) { println("key=" + entry.getKey() + ", value=" + entry.getValue()); }

 properties.put("nonString", 34);
 try {
  for (Map.Entry<String, String> e : Util.toMap(properties).entrySet()) {
   String s = e.getValue();
   Util.discard(s);
  }
  fail("expected exception");
 } catch (ClassCastException e) {
  // ok
 }
}
