How to switch redis Library in Springboot2.X
Use the Redis native method to use 16 databases at the same time, and continue to use the above pom file dependency
9. Redis tool class
Remember: the next version for Springboot2.1.X, including 2.0.X, 2.2.X, currently does not switch databases through the following.
Import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;import org.springframework.data.redis.core.StringRedisTemplate;import org.springframework.stereotype.Component;@Componentpublic class RedisUtil {@ Autowired private StringRedisTemplate redisTemplate; public void setRedisTemplate (StringRedisTemplate redisTemplate) {this.redisTemplate = redisTemplate;} public void setDataBase (int num) {LettuceConnectionFactory connectionFactory = (LettuceConnectionFactory) redisTemplate.getConnectionFactory () If (connectionFactory! = null & & num! = connectionFactory.getDatabase ()) {connectionFactory.setDatabase (num); this.redisTemplate.setConnectionFactory (connectionFactory); connectionFactory.resetConnection ();}} public StringRedisTemplate getRedisTemplate () {return this.redisTemplate;} public void set (String key, String value) {redisTemplate.opsForValue () .set (key, value) } / / get the value of the specified key public String get (String key) {return redisTemplate.opsForValue (). Get (key);}} 10, Controller test @ AutowiredRedisUtil redisUtil;@GetMapping ("/ test") public String test (String key) {for (int I = 1; I < 3; iSue +) {redisUtil.setDataBase (I); redisUtil.set (key, "" + I + key) } / / the development environment uses the following code, which simply tests to different redis databases / / redisUtil.setDataBase (RedisPartition.EIGHT.getOrdinal ()); return redisUtil.get (key);}
11. Summary
There are two ways to switch databases between jedis and StringRedisTemplate. I prefer to use jedis. With SringRedisTemplate, I don't copy all the redis methods too much.
12. Attach
The following is the configuration of ssm framework switching to use redis database at the same time, as for redis.xml and redis.properties to copy from the Internet.
@ Resource (name= "stringRedisTemplate") private StringRedisTemplate stringRedisTemplate;private StringRedisTemplate choseConnection (RedisConnectionEnum redisEnum) {JedisConnectionFactory factory = (JedisConnectionFactory) stringRedisTemplate.getConnectionFactory (); factory.setDatabase (redisEnum.getDbNum ()); stringRedisTemplate.setConnectionFactory (factory); return stringRedisTemplate;} is it helpful for you to read the above?
