  Ehcache利用Terracotta方式同步缓存 收藏
1.下载并安装Terracotta

http://www.terracotta.org/

2.启动Terracotta

bin/start-tc-server.bat 或 bin/start-tc-server.sh

3.代码
Set值类：

view plaincopy to clipboardprint?
package my.test.terracotta; 
 
import java.io.InputStream; 
 
import my.test.ehcache1.EHCacheTest; 
import net.sf.ehcache.Cache; 
import net.sf.ehcache.CacheManager; 
import net.sf.ehcache.Element; 
 
public class TestTerracottaSet { 
     
    public TestTerracottaSet() { 
        InputStream is = EHCacheTest.class.getResourceAsStream("/my/test/terracotta/ehcache.xml"); 
        CacheManager cacheManager = new CacheManager(is); 
        Cache cache = cacheManager.getCache("sampleTerracottaCache"); 
        for (int i = 0; i < 1001; i++) { 
            cache.put(new Element("key" + i, "value" + i)); 
        } 
    } 
 
    public static void main(String[] args) throws Exception { 
        new TestTerracottaSet(); 
    } 
} 

Get值类：

view plaincopy to clipboardprint?
package my.test.terracotta; 
 
import java.io.InputStream; 
 
import my.test.ehcache1.EHCacheTest; 
import net.sf.ehcache.Cache; 
import net.sf.ehcache.CacheManager; 
import net.sf.ehcache.Element; 
 
public class TestTerracottaGet { 
     
    public TestTerracottaGet() { 
        InputStream is = EHCacheTest.class.getResourceAsStream("/my/test/terracotta/ehcache.xml"); 
        CacheManager cacheManager = new CacheManager(is); 
        Cache cache = cacheManager.getCache("sampleTerracottaCache"); 
        for (int i = 0; i < 1001; i++) { 
            Element elem = cache.get("key" + i); 
            if (elem == null) { 
                System.out.println("key" + i + " not found"); 
            } else { 
                System.out.println("key" + i + "=" + elem.getValue()); 
            } 
        } 
    } 
 
    public static void main(String[] args) throws Exception { 
        new TestTerracottaGet(); 
    } 
} 

配置文件：修改官方样例配置文件，添加

view plaincopy to clipboardprint?
<terracottaConfig url="localhost:9510"/> 

view plaincopy to clipboardprint?
<cache name="sampleTerracottaCache" 
           maxElementsInMemory="1000" 
           eternal="false" 
           timeToIdleSeconds="3600" 
           timeToLiveSeconds="1800" 
           overflowToDisk="false"> 
        <terracotta/> 
    </cache> 

这是利用Terracotta服务器来进行缓存同步

4.运行

（1）先运行TestTerracottaSet类

（2）再运行TestTerracottaGet类

（3）运行结果：

key0=value0
key1=value1
key2=value2
key3=value3
key4=value4
key5=value5
key6=value6
key7=value7
key8=value8
key9=value9
key10=value10
......

key1000=value1000

可以通过Terrocotta控制台查看缓存情况，如图：
