1、将ehcache.xml文件放到src目录下

2、写个工具类

package com.common.utils;import java.net.URL;import net.sf.ehcache.Cache;import net.sf.ehcache.CacheManager;import net.sf.ehcache.Element;public class EhcacheUtil {    private static String path = "/ehcache.xml";    private URL url;    private CacheManager manager;         private static EhcacheUtil cacheUtil;        private  EhcacheUtil(String path){        url = this.getClass().getResource(path);        manager = CacheManager.create(url);    }        public static EhcacheUtil getInstance() {         if(cacheUtil == null){            synchronized (EhcacheUtil.class) {                if(cacheUtil == null){                    cacheUtil = new EhcacheUtil(path);                }            }        }        return cacheUtil;    }        public void put(String cacheName, String key, Object value) {         Cache cache = manager.getCache(cacheName);         Element element = new Element(key, value);         cache.put(element);     }         public Object get(String cacheName, String key) {         Cache cache = manager.getCache(cacheName);         Element element = cache.get(key);         return element == null ? null : element.getObjectValue();     }         public Cache get(String cacheName) {         return manager.getCache(cacheName);     }         public void remove(String cacheName, String key) {         Cache cache = manager.getCache(cacheName);         cache.remove(key);     } }

3、写个测试类

package com.test;import com.common.utils.EhcacheUtil;public class TestEhcache {    public static void main(String[] args) {        EhcacheUtil.getInstance().put("cacheTest", "test", "so easy!");        Object object = EhcacheUtil.getInstance().get("cacheTest", "test");        System.out.println((String)object);    }}

4、结束啦
