Spring-data-redis Configuration and usage examples

Spring-data-redis configuration and use examples

One, add maven dependency

<!-redis->
<dependency>
<groupId> org.springframework.data </ groupId>
<artifactId> spring-data-redis </ artifactId>
<version> 1.5.0.RELEASE </ version>
<scope> provided </ scope>
</ dependency>
<dependency>
<groupId> redis.clients </ groupId>
<artifactId> jedis </ artifactId>
<version> 2.6.3 </ version>
<scope> provided </ scope>
</ dependency>
<dependency>
<groupId> org.apache.commons </ groupId>
<artifactId> commons-pool2 </ artifactId>
<version> 2.3 </ version>
<scope> provided </ scope>
</ dependency>
<dependency>
<groupId> org.codehaus.jackson </ groupId>
<artifactId> jackson-core-asl </ artifactId>
<version> 1.9.13 </ version>
<scope> provided </ scope>
</ dependency>
<!-redis->
Second, redis.properties

## applicationContext-redis.xml
redis.ip = 192.168.1.156
redis.port = 6379
redis.timeout = 5000
redis.maxIdle = 10
redis.minIdle = 1
redis.maxTotal = 30
redis.maxWaitMillis = 5000
#testOnBorrow true indicates whether to check before removing the connection from the pool, if the test fails, remove the connection from the pool and try to remove another
redis.testOnBorrow = true
Three, apllicationContext-redis.xml

<? xml version = "1.0" encoding = "UTF-8"?>

</ bean>
<bean id = "redisTemplate" class = "org.springframework.data.redis.core.RedisTemplate">

</ bean>

</ beans>
Four, use examples

Five, the use of several data structures in redis

@Resource (name = "redisTemplate")
private RedisTemplate <String, String> template;
The tedisTemplate is assembled. All data types are operated by binding the type key first, and then the operation:

template.boundValueOps (stringKey);
template.boundHashOps (key);
template.boundListOps (key);
template.boundSetOps (key);
template.boundZSetOps (key);
