一、引入依赖

首先在pom.xml文件引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <version>2.2.6.RELEASE</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.8.0</version>
</dependency>

二、配置信息

在yml配置文件配置redis的服务信息（这里暂时只有单台）

spring:
  redis:
    host: 192.168.16.140
    port: 6379
    shutdown-timeout: 100
    lettuce:
      pool:
        max-idle: 8
        min-idle: 0
        max-active: 8
        max-wait: 10000
    timeout: 10000

三、新增配置文件

新增一个配置文件redisConfig.java,记得要加上注解@Configuration。另外要注意，启动类添加扫描注解能扫描得到该文件。

@Configuration
public class RedisConfig {

    @JsonIgnoreProperties(ignoreUnknown = true)
    @Bean
    @ConditionalOnMissingBean(name = "redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(
            RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {

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

        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(redisConnectionFactory);
        template.setKeySerializer(jackson2JsonRedisSerializer);
        template.setValueSerializer(jackson2JsonRedisSerializer);

        template.setHashValueSerializer(jackson2JsonRedisSerializer);

        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
        template.afterPropertiesSet();
        return template;
    }

    @Bean
    @ConditionalOnMissingBean(StringRedisTemplate.class)
    public StringRedisTemplate stringRedisTemplate(
            RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        return template;
    }
}

四、开启功能

在启动类上加上 @EnableCaching 注解

五、启动

完成上述四步，启动正常则表示整合成功。可以立马测试一下api。
