一、配置文件

本地redis服务

redis:
            host: 127.0.0.1
            port: 6379
            timeout: 0
            database: 0
            pool:
              max-active: 8
              max-wait: -1
              max-idle: 8
              min-idle: 0

二、pom依赖包

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-data-redis</artifactId>
       <version>1.5.7.RELEASE</version>
    </dependency>

三、RedisConfig配置类

package com.servingcloud.xszcloud.web.config;
    
    
    import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import org.springframework.cache.CacheManager;
    import org.springframework.cache.annotation.CachingConfigurerSupport;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.cache.interceptor.KeyGenerator;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.cache.RedisCacheManager;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    
    
    
    /**
     * Created by **
     * on 2018/9/30
     */
    @Configuration
    @EnableCaching
    public class RedisConfig extends CachingConfigurerSupport {
    
    
        @Bean
        public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory){
            StringRedisTemplate template = new StringRedisTemplate(factory);
            setSerializer(template);//设置序列化工具
            template.afterPropertiesSet();
            return template;
        }
        private void setSerializer(StringRedisTemplate template){
            @SuppressWarnings({ "rawtypes", "unchecked" })
            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);
            template.setValueSerializer(jackson2JsonRedisSerializer);
        }
    
        //缓存管理器
        @Bean
        public CacheManager cacheManager(RedisConnectionFactory factory) {
            RedisCacheManager cacheManager = RedisCacheManager.builder(factory).build();
            return cacheManager;
        }
    
    
        @Bean
        @Override
        public KeyGenerator keyGenerator() {
            return (target, method, objects) -> {
                StringBuilder sb = new StringBuilder();
                sb.append(target.getClass().getName());
                sb.append("::" + method.getName() + ":");
                for (Object obj : objects) {
                    sb.append(obj.toString());
                }
                return sb.toString();
            };
        }
    
    
    
    }

四、给启动类添加注解：`@EnableScheduling @EnableCaching`
