3.   简单的Redis测试程序
　　读者可以自行创建Eclipse项目，引入jedis的客户端包，测试程序如下：

 

public class RedisTest {
private Jedis jedis = null;
private String key1 = "key1";
private String key2 = "key2";
public RedisTest() {
jedis = new Jedis("localhost");
}
public static void main(String[] args) {
RedisTest redisTest = new RedisTest();
redisTest.isReachable();
redisTest.testData();
redisTest.delData();
redisTest.testExpire();
}
public boolean isReachable() {
boolean isReached = true;
try {
jedis.connect();
jedis.ping();
// jedis.quit();
} catch (JedisConnectionException e) {
e.printStackTrace();
isReached = false;
}
System.out
.println("The current Redis Server is Reachable:" + isReached);
return isReached;
}
public void testData() {
jedis.set("key1"， "data1");
System.out.println("Check status of data existing:"
+ jedis.exists(key1));
System.out.println("Get Data key1:" + jedis.get("key1"));
long s = jedis.sadd(key2， "data2");
System.out.println("Add key2 Data:" + jedis.scard(key2)
+ " with status " + s);
}
public void delData() {
long count = jedis.del(key1);
System.out.println("Get Data Key1 after it is deleted:"
+ jedis.get(key1));
}
public void testExpire() {
long count = jedis.expire(key2， 5);
try {
Thread.currentThread().sleep(6000);
} catch (InterruptedException e) {
e.printStackTrace();
}
if (jedis.exists(key2)) {
System.out
.println("Get Key2 in Expire Action:" + jedis.scard(key2));
} else {
System.out.println("Key2 is expired with value:"
+ jedis.scard(key2));
}
}
}
