本文整理了Java中org.apache.commons.collections.MultiMap类的一些代码示例，展示了MultiMap类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。MultiMap类的具体详情如下：
包路径：org.apache.commons.collections.MultiMap
类名称：MultiMap

MultiMap介绍

[英]Defines a map that holds a collection of values against each key.

A MultiMap is a Map with slightly different semantics. Putting a value into the map will add the value to a Collection at that key. Getting a value will return a Collection, holding all the values put to that key.

For example:

MultiMap mhm = new MultiHashMap(); 
mhm.put(key, "A"); 
mhm.put(key, "B"); 
mhm.put(key, "C"); 
Collection coll = (Collection) mhm.get(key);

coll will be a collection containing "A", "B", "C".

NOTE: Additional methods were added to this interface in Commons Collections 3.1. These were added solely for documentation purposes and do not change the interface as they were defined in the superinterface Map anyway.
[中]定义一个映射，该映射针对每个键保存一组值。
MultiMap是一个语义稍有不同的映射。将值放入地图将在该键处向集合添加值。获取一个值将返回一个集合，其中包含所有放入该键的值。
例如：

MultiMap mhm = new MultiHashMap(); 
mhm.put(key, "A"); 
mhm.put(key, "B"); 
mhm.put(key, "C"); 
Collection coll = (Collection) mhm.get(key);

coll将是一个包含“a”、“B”、“C”的集合。
注：Commons Collections 3.1中向该接口添加了其他方法。这些仅为文档目的而添加，不会更改superinterfaceMap中定义的接口。
