6.spring-boot2 ------redis

1.修改pom文件，添加redis依賴：

       <!--redis相關-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <!-- 添加jedis客戶端 -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>

2.spring配置文件修改[application.yml]：

spring:
  redis:
    database: 0
    host: 172.116.191.28
    port: 7443
    password:
    jedis:
      pool:
        max-active: 8
        max-idle: 8
        min-idle: 0
  cache:
    type: redis

3.創建redis配置類：

@EnableCaching
@Configuration
public class RedisConfig {
    private static final Logger LOGGER = LogManager.getLogger(RedisConfig.class);

    @Bean(name = "redisTemplate")
    public RedisTemplate<String, Object> getRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        //設置序列化
        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);
        // 配置redisTemplate
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        RedisSerializer stringSerializer = new StringRedisSerializer();
        // key序列化
        redisTemplate.setKeySerializer(stringSerializer);
        // value序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // Hash key序列化
        redisTemplate.setHashKeySerializer(stringSerializer);
        // Hash value序列化
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    @Bean(name = "redisUtil")
    public RedisUtil redisUtil(RedisTemplate<String, Object> redisTemplate) {
        RedisUtil redisUtil = new RedisUtil();
        redisUtil.setRedisTemplate(redisTemplate);
        return redisUtil;
    }
}
