integrated configuration springboot redis

Redis I will not introduce the benefits and introduction of , Direct installation and configuration ;

1、redis install

In this paper docker To install redis, It's also easy to install directly and locally , Download the installation package directly and then cmd Just start the window command line .

  1. Pull the mirror image
 Docker pull redis:4.0
  1. Start the mirror
 Docker run -itd --name redis-01 -p 6379:6379 # Mirror image id
  1. Release port
firewall-cmd --state # View firewall status
systemctl start firewalld.service # Start the firewall
firewall-cmd --zone=public --add-port=6379/tcp --permanent # Release port
system restart firewalld.service # service iptables restart
firewall-cmd --reload # service crond reload
firewall-cmd --list-all # View open ports 

2、Spring boot introduce

2.1、 introduce maven rely on


The introduction here is official starter, We used to use jedis, It can be more personal to change .

2.2、 Basic configuration

#Redis Server connection port
#Redis Server connection password ( The default is empty. )
# Maximum number of connections in connection pool ( Use a negative value to indicate that there is no limit )
# Connection pool maximum blocking wait time ( Use a negative value to indicate that there is no limit )
# The maximum free connection in the connection pool
# The smallest free connection in the connection pool
# Connection timeout ( millisecond )

The detailed configuration is changed according to personal needs . actually springboot There is a default configuration , It can be used without configuration .


package com.ssk.shop.bll;
* redis Operation interface
public interface IRedisBll {
* Store the data
void set(String key, String value);
* get data
String get(String key);
* Set the overdue time
boolean expire(String key, long expire);
* Delete data
void remove(String key);
* Self increment operation
* @param delta Self increasing step size
Long increment(String key, long delta);


package com.ssk.shop.bll.impl;
import com.ssk.shop.bll.IRedisBll;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.concurrent.TimeUnit;
public class IRedisBllImpl implements IRedisBll {
private StringRedisTemplate stringRedisTemplate;
public void set(String key, String value) {
stringRedisTemplate.opsForValue().set(key, value);
public String get(String key) {
return stringRedisTemplate.opsForValue().get(key);
public boolean expire(String key, long expire) {
return stringRedisTemplate.expire(key, expire, TimeUnit.SECONDS);
public void remove(String key) {
public Long increment(String key, long delta) {
return stringRedisTemplate.opsForValue().increment(key,delta);

Some basic methods can be encapsulated , Let some ordinary operations more convenient to achieve .

summary :redis Is a good cache processing scheme , Projects can always be used by users to cache some commonly used information , Reduce the pressure of accessing database , It's also an optional option for some seckill programs , So far, there will be some permissions in the project as well as on token use redis Do unique login control ( single token take effect ).
