1.How to build project by maven?

Type command "mvn -Dtest -DfailIfNoTests=false assembly:assembly" to build the project.Maven will download the dependencies automacly and build project.


2.How to run unit tests?

The test.properties file under the src/test/resources folder is used for setting memcached test server.
Please set test.memcached.servers property,Then run the AllTests class with jvm option "-ea".

3.Is Xmemcached compatible with jdk5?
Yes,since 1.2.0-RC1,Xmemcached is compatible with jdk5.

#New a XMemcachedClient instance

 XMemcachedClientBuilder builder = new XMemcachedClientBuilder(
           AddrUtil.getAddresses("localhost:11211"));
 XMemcachedClient client=builder.build();
 
#If you want to use binary protocol(use memcached 1.4.0 and xmemcached 1.2.0)
  XMemcachedClientBuilder builder = new XMemcachedClientBuilder(
           AddrUtil.getAddresses("localhost:11211"));
  builder.setCommandFactory(new BinaryCommandFactory());
  XMemcachedClient client=builder.build();
 
#If you want to use xmemcached talking with kestrel
  XMemcachedClientBuilder builder = new XMemcachedClientBuilder(
           AddrUtil.getAddresses("localhost:11211"));
  builder.setCommandFactory(new KestrelCommandFactory());
  XMemcachedClient client=builder.build();

#If you want to store primitive type as String
  client.setPrimitiveAsString(true);

#add or remove memcached server dynamically 

client.addServer("localhost:12001 localhost:12002");

#get operation

String name =client.get("test");

#set add replace append prepend gets

client.add("hello", 0, "dennis");
client.replace("hello", 0, "dennis");
client.append("hello", 0, " good");
client.prepend("hello", 0, "hello ");
GetsResponse response=client.gets("hello");
long cas=response.getCas();
Obejct value=response.getValue();

#incr decr
client.set("a",0,"1");
client.incr("a",4); 
client.deccr("a",4); 

#cas

});

#flush_all
client.flushAll();

#stats
Map<InetSocketAddress,Map<String,String>> result=client.getStats();

# get server versions
Map<InetSocketAddress,String> version=memcached.getVersions();

#bulk get
List<String> keys = new ArrayList<String>();
keys.add("hello");
keys.add("test");
Map<String, Object> map = client.get(keys);

#Enable jmx support

#Set server's weight

//set weight to 2
client.addServer("localhost",12000,2); 

//or through XMemcachedClientBuilder,pass a weight array to XMemcachedClientBuilder constructor
