spring-boot - 整合Reids(单机版)

【spring-boot - 整合Reids(单机版)】

1.引入依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--SpringBoot与Redis整合依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
        </dependency>


2.配置application.properties

server.port=8080
server.servlet.encoding.charset=UTF-8
# 应用名称
spring.application.name=redis-sample
spring.jackson.date-format='yyyy-MM-dd HH:mm:ss'
spring.jackson.time-zone=GMT+8

# always：始终包含该属性，与该属性的值无关; non_null：属性字段值为空则不会返回该字段，即value为null则key不被返回
spring.jackson.default-property-inclusion=always

spring.mvc.pathmatch.matching-strategy=ant_path_matcher

# ===============================redis single node config=================================
spring.redis.database=0
spring.redis.host=192.168.xxx.xxx
spring.redis.port=6379
# 连接密码
spring.redis.password=******

# 连接池配置，这里使用的lettuce
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-wait=-1ms
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.min-idle=0



3.出于序列化考虑，编写配置类：RedisConfig，指定RedisTemplate对应的key-value序列化方式

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {

        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();

        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        //设置key序列化方式: string
        redisTemplate.setKeySerializer(new StringRedisSerializer());

        //设置value的序列化方式json，使用 GenericJackson2JsonRedisSerializer 替换默认序列化
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());


        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());

        redisTemplate.afterPropertiesSet();
        return redisTemplate;

    }


}


4.使用

    @Autowired
    private RedisTemplate redisTemplate;

    // 写入
    redisTemplate.opsForValue().set(key, value);
    // 获取
    Object obj = redisTemplate.opsForValue().get(key);
