本文详细介绍了如何在Spring Boot项目中配置和使用Redis，包括配置文件设置、pom依赖包引入、自定义RedisConfig配置类以及启动类注解的添加。通过具体代码示例，展示了序列化工具的设置、缓存管理器的实现和键生成器的自定义，为开发者提供了全面的Redis集成指南。

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

<!-- Spring Boot Redis 依赖 -->
<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
