Redis SPRINGMVC Configuration and application

1. Create a Constantutil class

/**
* Redis Profile Name
*/
Public final static String redis_file_name_config = "Redis.properties";

2. Add the Pom file

<!--Https://mvnrepository.com/artifact/redis.clients/jedis--
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>

3. Configure a Redis configuration file

#redis服务器IP
redis.addr=10.12.12.140

#redis的端口号
redis.port=6379

#可用连接实例的最大数目, the default is 8 if the assignment is-1, it means no limit, and if the pool is already assigned maxactive Jedis instances, the pool's state is exhausted (exhausted).
redis.maxactive=1024

#控制一个pool最多有多少个状态为idle (Idle) instance of Jedis, which is also 8 by default
redis.maxidle=200

#等待可用连接的最大时间, in milliseconds, the default value is-1, which means that never times out. If the wait time is exceeded, the jedisconnectionexception is thrown directly
redis.maxwait=10000

#初始化连接池超时时间
redis.timeout=10000

4, write Redisutil tool class

Whether the validate operation is performed in advance when a Redis instance is borrow;
If true, the resulting Jedis instances are available
private static Boolean Test_on_borrow = true;

private static Jedispool Jedispool = null;
