本文详细介绍了如何在Spring Boot项目中配置和使用Redis，包括配置文件的设置、Jedis连接池的创建、RedisTemplate的定制化配置，以及如何通过Redis进行数据缓存和操作。

propertites配置redis
spring.redis.database=1
spring.redis.host=106.14.9.199
spring.redis.port=16379
spring.redis.password=tc123456
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=0

配置文件：

一、

import com.huashui.sys.advice.GlobalControllerAdvice;
import groovy.util.logging.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

/**
 * @Author: 
 * @Date: 
 */

@Configuration
@EnableCaching
@ConfigurationProperties(prefix="spring.redis")
public class JedisConfiguration extends CachingConfigurerSupport {

    private static final Logger logger = LoggerFactory.getLogger(GlobalControllerAdvice.class);

    @Value("${spring.redis.host}")
    private String host;

    @Value("${spring.redis.port}")
    private int port;

    @Value("${spring.redis.timeout}")
    private int timeout;

    @Value("${spring.redis.pool.max-idle}")
    private int maxIdle;

    @Value("${spring.redis.pool.max-wait}")
    private long maxWaitMillis;

    @Value("${spring.redis.password}")
    private String password;

    @Value("${spring.redis.pool.max-active}")
    private int maxTotal;


    @Bean
    public JedisPool redisPoolFactory() {
        logger.info("JedisPool注入成功！！");
        logger.info("redis地址：" + host + ":" + port);
//        getJedisConfiguration();
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(maxIdle);
        jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
        //最大连接数, 默认8个
        jedisPoolConfig.setMaxTotal(maxTotal);

        JedisPool jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout, password);

        return jedisPool;
    }
}

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

/**

@Configuration
@EnableAutoConfiguration
public class RedisConfig {

    // 使用工厂初始化redis操作模板
    @Bean
    public RedisTemplate<?, ?> getRedisTemplate(JedisConnectionFactory jedisConnectionFactory) {

        RedisTemplate<String, String> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(jedisConnectionFactory);

        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // key序列化方式,但是如果方法上有Long等非String类型的话，会报类型转换错误
        // Long类型不可以会出现异常信息;
        redisTemplate.setKeySerializer(new StringRedisSerializer());
//        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
//    @Bean

//        // 设置值（value）的序列化采用FastJsonRedisSerializer。
//        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
////        redisTemplate.setHashValueSerializer(fastJsonRedisSerializer);
//        // 设置键（key）的序列化采用StringRedisSerializer。

//        redisTemplate.afterPropertiesSet();

    @Value("${spring.redis.database}")

    @Bean
    public Jedis jedis(){
        Jedis jedis = new Jedis(host,port);
        if(StringUtils.isNotBlank(password)){
            jedis.auth(password);
        }
        jedis.select(index);
        return jedis;
    }
}

登录是把token放到缓存中

redisTemplate.opsForValue().set(token + "_user", sysUser, 2, TimeUnit.HOURS);
redisTemplate.opsForValue().set(token + "_area", area, 2, TimeUnit.HOURS);
//该用于标会系统
jedis.setex(token + "_userId", 7200,sysUser.getId());
jedis.setex(token + "_areaId", 7200,area.getId());
jedis.setex(token + "_gov_code", 7200,sysUser.getGovCode());
String areaCode = sysUser.getGovCode().split("_")[1];
SysArea aa = sysAreaService.getSysAreaByAreaCode(areaCode, sysUser.getGovCode());
redisTemplate.opsForValue().set(sysUser.getGovCode(), aa, 10, TimeUnit.DAYS);
