Spring Integrated Redis client Jedis (Java)

Jedis is a Redis Java client, and spring configures the Redis connection pool as a bean.

"Redis.clients.jedis.JedisPool", which is a Redis connection pool for stand-alone environments.

1. Maven imports the relevant package:

    <!--redis Dependencies--    <dependency>      <groupId>redis.clients</groupId>      < artifactid>jedis</artifactid>      <version>2.9.0</version>    </dependency>

2, the following is the configuration of the Redis connection pool in a single machine environment:

<?xml version= "1.0" encoding= "UTF-8"?>
<beans xmlns= "Http://www.springframework.org/schema/beans"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
xmlns:context= "Http://www.springframework.org/schema/context"
Xsi:schemalocation= "Http://www.springframework.org/schema/beans
Http://www.springframework.org/schema/beans/spring-beans.xsd
Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd " >

<!--introducing the properties configuration file for Jedis--
<!--If you have multiple data sources that need to be managed by <context:property-placeholder and do not want to be placed in a configuration file, be sure to add ignore-unresolvable= "true"-
<context:property-placeholder location= "Classpath:properties/redis.properties" ignore-unresolvable= "true"/ >

<!--related configuration--> for Jedis connection pool;
<bean id= "Jedispoolconfig" class= "Redis.clients.jedis.JedisPoolConfig" >
<!--new version is Maxtotal, the old version is maxactive-->
<property name= "Maxtotal";
<value>${ Redis.pool.maxactive}</value>
</property>
<property name= "Maxidle";
<value>${ Redis.pool.maxidle}</value>
</property>
<property name= "Testonborrow" value= "true"/>
<property name= "Testonreturn" value= "true"/>
</bean>

<bean id= "Jedispool" class= "Redis.clients.jedis.JedisPool" >
<constructor-arg name= "Poolconfig" ref= "Jedispoolconfig"/>
<constructor-arg name= "host" value= "${redis.host}"/>
<constructor-arg name= "Port" value= "${redis.port}" type= "int"/>
<constructor-arg name= "Timeout" value= "${redis.timeout}" type= "int"/>
<constructor-arg name= "Password" value= "${redis.password}"/>
<constructor-arg name= "Database" value= "${redis.database}" type= "int"/>
</bean>
</beans>

3, the corresponding Classpath:properties/redis.properties.xml is:

#最大分配的对象数redis. pool.maxactive=200# the maximum number of objects that can hold the Idel state redis.pool.maxidle=50redis.pool.minidle= 10redis.pool.maxwaitmillis=20000# when no object is returned in the pool, the maximum wait time redis.pool.maxwait=300# format: redis://:[password]@[server address]:[Port]/[db Index]redis.uri = Redis://:[email Protected]:6379/0redis.host = 127.0.0.1redis.port = 6379redis.timeout= 30000redis.password = 12345redis.database = 0

4, Redisutil

Package com.ctid.business.redis.util;

Import Javax.annotation.Resource;

Import org.springframework.stereotype.Component;

Import Redis.clients.jedis.Jedis;
Import Redis.clients.jedis.JedisPool;
@Component
public class Redisutil {

@Resource
Private Jedispool jedispool;//Injection Jedispool

public string get (string key) {//Gets the value of the specified key. If key does not exist, return nil
Jedis Jedis = Jedispool.getresource ();
String string = Jedis.get (key);
Jedis.close ();
return string;
}

public string Set (string key, String value) {//Set some string value
Jedis Jedis = Jedispool.getresource ();
String string = Jedis.set (key, value);
Jedis.close ();
return string;
}

public string Hget (string hkey, String key) {//Gets the value of the specified field in the hash table
Jedis Jedis = Jedispool.getresource ();
String string = Jedis.hget (hkey, key);
Jedis.close ();
return string;
}

Public long Hset (string hkey, String key, String value) {//To assign a value to a field in a hash table
Jedis Jedis = Jedispool.getresource ();
Long result = Jedis.hset (hkey, key, value);
Jedis.close ();
return result;
}

Public long incr (String key) {//Adds a number value stored in key, if key does not exist, then the value of key is first initialized to
0, and then perform the incr operation
Jedis Jedis = Jedispool.getresource ();
Long result = JEDIS.INCR (key);
Jedis.close ();
return result;
}

Public long expire (String key, int second) {//Set expiry time for key
Jedis Jedis = Jedispool.getresource ();
Long result = Jedis.expire (key, second);
Jedis.close ();
return result;
}

Public long TTL (String key) {//Returns the remaining expiration time of key in seconds
Jedis Jedis = Jedispool.getresource ();
Long result = Jedis.ttl (key);
Jedis.close ();
return result;
}

Public long del (String key) {//deleted by key
Jedis Jedis = Jedispool.getresource ();
Long result = Jedis.del (key);
Jedis.close ();
return result;
}

Public long Hdel (string hkey, String key) {//delete one or more specified fields in the hash table key
Jedis Jedis = Jedispool.getresource ();
Long result = Jedis.hdel (hkey, key);
Jedis.close ();
return result;
}

}

5. Redisutil Call

Package Com.ctid.business.redis.testIpv6;

Import Javax.annotation.Resource;

Import Org.apache.commons.logging.Log;
Import Org.apache.commons.logging.LogFactory;
Import Org.springframework.stereotype.Service;

Import Com.ctid.business.redis.util.RedisUtil;

@Service
public class TestIpv6 {

private static final Log LOGGER = Logfactory.getlog (Testipv6.class);
@Resource
Private Redisutil Redisutil;

public void TestIpv6 () {
Logger.info ("redis======================================");
String RESULT1 = redisutil.set ("Test", "1111");
Logger.info ("Redis Setting Value:" + result1);
String result2 = redisutil.get ("test");
Logger.info ("Redis Query Value:" + result2);

}

}
