一、LRU算法介绍
LRU（Least Recently Used）最近最少使用算法，是用在操作系统中的页面置换算法，因为内存空间是有限的，不可能把所有东西都放进来，所以就必须要有所取舍，我们应该把什么东西放进来呢？有没有什么判定标准呢？页面置换算法就是干这个的，企图通过之前的行为预测到之后的行为（这是概率问题），而LRU就是其中的一种，它的基本思想就是既然有一块数据，最近的一段时间内它是最少访问的，这说明在这之后它也可能是最少访问的，如果非要移除一个的话，我只好把它置换出内存了。
总结一下：
LRU：在空间有限的情况下必须做出取舍，将最可能最少被访问的数据置换掉。
二、为什么使用LRU
QUESTION： 我用HashMap也挺好的啊，为什么要使用缓存昂？！
用数据说话，做一个实验来说明为什么要使用缓存，new两个Map底层分别使用HashMap和LinkedHashMap，然后往里面装一百万条数据，然后分别总是访问同一条数据十万次和随机访问十万次：
import java.util.HashMap;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Random; public class Main { public static void main(String[] args) { Map<Integer,Integer> map1=new LinkedHashMap<Integer,Integer>(,0.75F,true);
Map<Integer,Integer> map2=new HashMap<Integer,Integer>(); for(int i=;i<;i++){
map1.put(i,i);
map2.put(i,i);
} // 大量访问同一条数据
long start=System.currentTimeMillis();
for(int i=;i<;i++){
map1.get();
}
System.out.printf("HashMap: %dms\n",System.currentTimeMillis()-start); start=System.currentTimeMillis();
for(int i=;i<;i++){
map2.get();
}
System.out.printf("LinkedHashMap: %dms\n",System.currentTimeMillis()-start); //随机访问数据
start=System.currentTimeMillis();
for(int i=;i<;i++){
map1.get();
}
System.out.printf("HashMap: %dms\n",System.currentTimeMillis()-start); start=System.currentTimeMillis();
for(int i=;i<;i++){
map2.get(new Random().nextInt());
}
System.out.printf("LinkedHashMap: %dms\n",System.currentTimeMillis()-start); } }
结果如下：

首先进行横向比较，无论怎么访问LinkedHashMap总是要比HashMap快得多，
然后进行纵向比较发现HashMap访问同一条数据和随机访问花费的时间差不多，因为它是无状态的，也就是它并不能根据之前的结果帮助到以后的查询，LinkedHashMap的随机访问明显要慢一些了，LRU的策略主要就是用于短时间内频繁的访问相同的数据的。
三、如何使用LinkedHashMap实现LRUMap
继承LinkedHashMap然后覆写removeEldestEntry方法即可，这个方法在每次添加元素之前调用来判断是否需要删除元素，如果需要的话就会用LRU算法移除掉最近最少使用的元素，如下：
import java.util.Iterator;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Map.Entry; public class Main { public static void main(String[] args) { Map<Integer,Integer> map=new LRUMap<>(); map.put(,);
map.put(,);
map.put(,);
map.get();
map.put(,);
map.put(,); for(Iterator<Entry<Integer,Integer>> iter=map.entrySet().iterator();iter.hasNext();){
System.out.print(iter.next().getKey()+" "); //2 7 11
} } } class LRUMap<K,V> extends LinkedHashMap<K,V>{ private int capacity; public LRUMap() {
this();
} public LRUMap(int capacity) {
super(capacity,0.75F,true);
this.capacity=capacity;
} @Override
protected boolean removeEldestEntry(java.util.Map.Entry<K, V> eldest) {
return size()>capacity;
} }
