Java traversal reads the entire Redis database instance _java

Redis provides a flexible way of querying data, and the most bull is the search for key to support regular expressions.

Jedis.keys ("*") means search for all key
Jedis.keys ("abc*") indicates the search for key data beginning with ABC

The key is traversed to the value.

is actually a set

Copy Code code as follows:

Redisdo rd = new redisdo ();
Rd.open ();
Set s = Rd.jedis.keys ("*");
Iterator it = S.iterator ();


while (It.hasnext ()) {
String key = (string) it.next ();
String value = Rd.jedis.get (key);
SYSTEM.OUT.PRINTLN (key + value);
}
Rd.close ();

RD's algorithm for integrated Redis operations

Copy Code code as follows:

Package Com.javaer.click.way;

Import Redis.clients.jedis.Jedis;
Import Redis.clients.jedis.JedisPool;
Import Redis.clients.jedis.JedisPoolConfig;
Import redis.clients.jedis.exceptions.JedisConnectionException;

public class Redisdo {
Public Jedis Jedis;

public void Close () {
Jedis.disconnect ();
Jedis = null;
}

Public Jedis open () {
Jedispoolconfig config = new Jedispoolconfig ();

Config.setmaxactive (100);

Config.setmaxidle (20);

Config.setmaxwait (1000l);
Jedispool Pool;
Pool = new Jedispool (config, "xxxxxxxx.xx.xx.xx", 6379);

Boolean borroworoprsuccess = true;
try {
Jedis = Pool.getresource ();
Do Redis opt by instance
catch (Jedisconnectionexception e) {
Borroworoprsuccess = false;
if (Jedis!= null)
Pool.returnbrokenresource (Jedis);

finally {
if (borroworoprsuccess)
Pool.returnresource (Jedis);
}
Jedis = Pool.getresource ();
return Jedis;
