利用*.properties定义文件对类进行初始化或通过xml注入

public class EhCache*** implements PCache {
	private  int maxElementsInMemory = Integer.parseInt(ResourceBundle.getBundle("cache")
			.getString("cache.maxElementsInMemory").toString());
	private  boolean overflowToDisk = Boolean.getBoolean(ResourceBundle.getBundle("cache")
			.getString("cache.overflowToDisk").toString());
	private  boolean eternal = Boolean.getBoolean(ResourceBundle.getBundle("cache")
			.getString("cache.eternal").toString());
	private  long timeToIdleSeconds = Long.parseLong(ResourceBundle.getBundle("cache")
			.getString("cache.timeToIdleSeconds").toString());;
	private  long timeToLiveSeconds = Long.parseLong(ResourceBundle.getBundle("cache")
			.getString("cache.timeToLiveSeconds").toString());;
	Cache cache = null;   
	public EhCache***(String cacheName){
		cache = new Cache(cacheName,this.getMaxElementsInMemory(),this.isOverflowToDisk(),this.isEternal(),this.getTimeToLiveSeconds(),this.getTimeToIdleSeconds());
         }

不过最好用Sring的Bundle

也可以这样初始化

public class EhCache** implements PCache {
	private  int maxElementsInMemory;
	private  boolean overflowToDisk;
	private  boolean eternal;
	private  long timeToIdleSeconds;
	private  long timeToLiveSeconds;
	private String cacheName = "";
    CacheManager manager = CacheManager.create();
    private  Cache cache = null;
    
	public EhCache**(String cacheName){
		this.cacheName = cacheName;
	}
	public void init(){		
	     cache = new Cache(this.cacheName,this.getTimeToIdleSeconds());
			
	}

}

在xml中,通过注入属性对其进行初始化
<bean id="ehCache" class="com.yk.platform.cache.impl.EhCache*" scope="singleton" init-method="init">
           <constructor-arg type="java.lang.String">
             <value>newCache</value>
           </constructor-arg>
           <property name = "maxElementsInMemory" value="500"></property>
           <property name = "eternal" value="false"></property>
           <property name = "timeToIdleSeconds" value="300"></property>
           <property name = "timeToLiveSeconds" value="1200"></property>
           <property name = "overflowToDisk" value="true"></property>
     </bean>
