SpringBoot configuration redis and distributed session-redis method (code)

The content of this article is about the method (code) of configuring redis and distributed session-redis in SpringBoot. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The difference between springboot project and traditional project configuration redis is simpler and more convenient. In a distributed system, to solve the session sharing problem, spring session redis can be used.

1, pom.xml

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
<dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>

2, rdis configuration class

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.JedisPoolConfig;
import redis.clients.jedis.JedisShardInfo;
import redis.clients.jedis.ShardedJedisPool;

import java.util.ArrayList;
import java.util.List;

@Configuration
public class RedisConfig extends CachingConfigurerSupport {

    @Value("${redis.host}")
    private String host;
    @Value("${redis.port}")
    private Integer port;
    @Value("${redis.maxTotal}")
    private Integer maxTotal;
    @Value("${redis.maxIdle}")
    private Integer maxIdle;
    @Value("${redis.maxWaitMillis}")
    private Long maxWaitMillis;

    @Bean
    public ShardedJedisPool shardedJedisPool() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(maxTotal);
        jedisPoolConfig.setMaxIdle(maxIdle);
        jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
        List<JedisShardInfo> jedisShardInfos = new ArrayList<>();
        jedisShardInfos.add(new JedisShardInfo(host,port));
        return  new ShardedJedisPool(jedisPoolConfig, jedisShardInfos);
    }

}

3, session redis configuration class

import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
/**
 * session共享
 */
@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds=60*60)
public class RedisSessionConfig {
}
