我有一个存储了大量的映射从字符串到各种对象的Java程序。

I have a Java program that stores a lot of mappings from Strings to various objects.

现在，我的选择是要么依赖（通过HashMap的）或二进制搜索（通过TreeMap中）散列。我想知道是否有一个流行及品质的集合库的高效，规范线索为基础的Map实现？

Right now, my options are either to rely on hashing (via HashMap) or on binary searches (via TreeMap). I am wondering if there is an efficient and standard trie-based map implementation in a popular and quality collections library?

我已经写了我自己的过去，但我宁愿用什么标准去了，如果有的话。

I've written my own in the past, but I'd rather go with something standard, if available.

快速澄清：虽然我的问题是，一般情况下，在当前项目中，我处理大量的数据，是通过完全限定类名或方法签名索引。因此，有许多共享prefixes。

Quick clarification: While my question is general, in the current project I am dealing with a lot of data that is indexed by fully-qualified class name or method signature. Thus, there are many shared prefixes.
