详解Spring MVC 集成EHCache缓存

废话少说，直接上代码：

ehcache.xml 文件

需要增加的JAR包

springmvc.xml 需要在beans增加以下

xmlns:cache="http://www.springframework.org/schema/cache"
http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd

增加bean

EHCacheUtils 操作类

import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;

/**
 * 操作缓存类
 * 
 * @author jiangadam
 */

public class EhcacheUtils {

  private static final String path = "/config/ehcache.xml"; // EHCache 的配置文件地址

  private CacheManager manager;

  private static EhcacheUtils ehCache;

  private EhcacheUtils(String path) {
    manager = CacheManager.create(getClass().getResource(path));
  }

  public static EhcacheUtils getInstance() {
    if (ehCache == null) {
      ehCache = new EhcacheUtils(path);
    }
    return ehCache;
  }

  /**
   * 缓存一个对象
   * 
   * @param cacheName
   *      缓存的名字
   * @param key
   *      缓存的KEY
   * @param value
   *      缓存的值
   */
  public void put(String cacheName, String key, Object value) {
    Cache cache = manager.getCache(cacheName);
    Element element = new Element(key, value);
    cache.put(element);
  }

  /**
   * 获取一个缓存的对象，没有返回NULL
   * 
   * @param cacheName
   * @param key
   * @return
   */
  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);
  }

}

PUT 写入缓存

GET 获取缓存的数据
