springboot3.3.4链接redis

1、引入依赖

在 pom.xml 文件中添加 Redis 相关的依赖：

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-data-redis</artifactId>
     <version>3.3.4</version>
</dependency>
<dependency>
     <groupId>redis.clients</groupId>
     <artifactId>jedis</artifactId>
     <version>5.2.0</version>
</dependency>

2. 配置 Redis

在 application.yml 或 application.properties 中添加 Redis 配置信息：

使用 application.yml：

spring:
  redis:
    data:
      host: 127.0.0.1
      port: 6380
      database: 0

3、配置bean

配置 RedisTemplate

在大多数场景中，使用 RedisTemplate 来操作 Redis 数据：

创建自定义的 RedisTemplate Bean：

package com.leafboat.bookhome.user.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
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(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 设置 Key 序列化器
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());

        // 设置 Value 序列化器
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());

        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

4. 使用 RedisTemplate

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

@Service
public class RedisService {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public void saveData(String key, Object value) {
        redisTemplate.opsForValue().set(key, value);
    }

    public Object getData(String key) {
        return redisTemplate.opsForValue().get(key);
    }

    public void deleteData(String key) {
        redisTemplate.delete(key);
    }
}
