没有参考代码的时候重新写还是有点累的，这是重温了，第一次写的时候参考了别的一些乱七八糟的代码，虽然不是和这个一样的，不过在不懂的情况下还是很快写出来了，反而是这次光是找需要哪些jar都搞了半天，最后发现extern的用一个jar就够了，addresses和auth之前也是糊里糊涂的，这次总算搞清楚了
maven引入
<dependency> <groupId>com.googlecode.xmemcached</groupId> <artifactId>xmemcached</artifactId> <version>1.4.3</version> </dependency>
先按照在前面的一篇《记一次couchbase（memcached）安装以及使用》的步骤安装好，类型选择couchbase就行了，
测试代码如下：
package Test.test; import java.io.IOException; import java.util.concurrent.TimeoutException; import net.rubyeye.xmemcached.MemcachedClient; import net.rubyeye.xmemcached.MemcachedClientBuilder; import net.rubyeye.xmemcached.XMemcachedClientBuilder; import net.rubyeye.xmemcached.auth.AuthInfo; import net.rubyeye.xmemcached.command.BinaryCommandFactory; import net.rubyeye.xmemcached.exception.MemcachedException; import net.rubyeye.xmemcached.utils.AddrUtil; public class App { public static void main( String[] args ) { try { MemcachedClientBuilder builder = new XMemcachedClientBuilder(AddrUtil.getAddresses("192.168.92.128:11211")) ; builder.addAuthInfo(AddrUtil.getOneAddress("192.168.92.128:11211"), AuthInfo.plain("azul", "xxxx")); builder.setCommandFactory(new BinaryCommandFactory()); builder.setFailureMode(true); builder.setConnectionPoolSize(10); MemcachedClient client = builder.build(); client.set("lwk", 0, "hello"); String value = client.get("key"); System.out.println(value); client.shutdown(); } catch (IOException e) { e.printStackTrace(); } catch (TimeoutException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } catch (MemcachedException e) { e.printStackTrace(); } System.out.println( "end..." ); } }
执行结果：
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. hello end...
管理界面上可以看到：
它是密文存储的
如果不用sasl验证的话先把服务器上的验证去掉然后这样写
package Test.test; import net.spy.memcached.AddrUtil; import net.spy.memcached.MemcachedClient; public class App { public static void main( String[] args ) { try { MemcachedClient client = new MemcachedClient(AddrUtil.getAddresses("192.168.92.128:11211")); client.set("lwk", 0, "hello"); Object value = client.get("lwk"); System.out.println(value); client.shutdown(); } catch (Exception e) { e.printStackTrace(); } System.out.println( "end..." ); } }
结果：
2015-03-01 23:26:38.268 INFO net.spy.memcached.MemcachedConnection: Added {QA sa=/192.168.92.128:11202, #Rops=0, #Wops=0, #iq=0, topRop=null, topWop=null, toWrite=0, interested=0} to connect queue

hello
end...
2015-03-01 23:26:38.284 INFO net.spy.memcached.MemcachedConnection: Shut down memcached client
这里是通过java client访问，一会儿用命令行试一下。
