Spring整合Redis的步骤如下:

  1. 添加依赖

在项目的pom.xml文件中添加Spring Boot和Redis的依赖。例如,使用Spring Boot Starter Data Redis:

<dependencies>
    <!-- Spring Boot Starter Data Redis -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <!-- Redisson for distributed locks and other features -->
    <dependency>
        <groupId>org.redisson</groupId>
        <artifactId>redisson</artifactId>
        <version>3.16.1</version>
    </dependency>
</dependencies>
  1. 配置Redis

在application.properties或application.yml文件中配置Redis连接信息。例如:

# Redis connection settings
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=
spring.redis.database=0
spring.redis.timeout=60000
  1. 创建Redis配置类

创建一个配置类,用于初始化RedisTemplate和StringRedisTemplate。例如:

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.afterPropertiesSet();
        return template;
    }

    @Bean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(factory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new StringRedisSerializer());
        template.afterPropertiesSet();
        return template;
    }
}
  1. 使用RedisTemplate

在你的服务类中,注入RedisTemplate,然后使用它来操作Redis数据。例如:

@Service
public class MyService {

    @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);
    }
}
  1. 使用Redisson(可选)

如果你需要分布式锁和其他高级功能,可以集成Redisson。首先,添加Redisson依赖:

<dependency>
    <groupId>org.redisson</groupId>
    <artifactId>redisson</artifactId>
    <version>3.16.1</version>
</dependency>

然后,在配置类中初始化RedissonClient:

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
public class RedissonConfig {

    @Bean
    public RedissonClient redissonClient() {
        Config config = new Config();
        config.useSingleServer()
                .setAddress("redis://127.0.0.1:6379");
        return Redisson.create(config);
    }
}

在你的服务类中,注入RedissonClient,然后使用它来操作Redis数据。例如:

@Service
public class MyService {

    @Autowired
    private RedissonClient redissonClient;

    public void saveData(String key, Object value) {
        RLock lock = redissonClient.getLock(key);
        lock.lock();
        try {
            redisTemplate.opsForValue().set(key, value);
        } finally {
            lock.unlock();
        }
    }

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

这样,你就完成了Spring整合Redis的步骤。现在你可以使用RedisTemplate或RedissonClient来操作Redis数据了。
