1.pom 依赖

<dependency>
    	        <groupId>org.springframework.boot</groupId>
    	        <artifactId>spring-boot-starter-data-redis</artifactId>
    	        <exclusions>
    		        <exclusion>
    		            <groupId>io.lettuce</groupId>
    		            <artifactId>lettuce-core</artifactId>
    		        </exclusion>
    		    </exclusions>
    	    </dependency>
    	    <dependency>
    		    <groupId>redis.clients</groupId>
    		    <artifactId>jedis</artifactId>
    		</dependency>

2. application.properties 配置文件

#===========Redis配置===========
    # Redis数据库索引（默认为0）  
    spring.redis.database=0
    # Redis服务器地址  
    spring.redis.host=127.0.0.1
    # Redis服务器连接端口  
    spring.redis.port=6379
    # Redis服务器连接密码（默认为空）  
    spring.redis.password=root
    # 连接池最大连接数（使用负值表示没有限制）  
    spring.redis.pool.max-active=200
    # 连接池最大阻塞等待时间（使用负值表示没有限制）  
    spring.redis.pool.max-wait=-1
    # 连接池中的最大空闲连接 
    spring.redis.pool.max-idle=10
    # 连接池中的最小空闲连接  
    spring.redis.pool.min-idle=0
    # 连接超时时间（毫秒）
    spring.redis.timeout=2000ms
    spring.redis.jedis.pool.max-wait=-1ms
    #===========Redis配置===========

3. config 配置类

package org.fh.config;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
    
    import com.fasterxml.jackson.databind.ObjectMapper;
    import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.annotation.JsonAutoDetect;
    
    /**
     * 说明：Redis
     * 作者：FH
     * java www.fhadmin.org
     */
    @Configuration
    public class RedisConfig {
    
    	@Bean
    	@SuppressWarnings("all")
    	public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
    		RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
    		template.setConnectionFactory(factory);
    		Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    		ObjectMapper om = new ObjectMapper();
    		om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    		om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance , ObjectMapper.DefaultTyping.NON_FINAL);
    		jackson2JsonRedisSerializer.setObjectMapper(om);
    		StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
    		// key采用String的序列化方式
    		template.setKeySerializer(stringRedisSerializer);
    		// hash的key也采用String的序列化方式
    		template.setHashKeySerializer(stringRedisSerializer);
    		// value序列化方式采用jackson
    		template.setValueSerializer(jackson2JsonRedisSerializer);
    		// hash的value序列化方式采用jackson
    		template.setHashValueSerializer(jackson2JsonRedisSerializer);
    		template.afterPropertiesSet();
    		return template;
    	}
    
    }
