Spring整合Redis的步骤如下:
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>
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
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;
}
}
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);
}
}
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。
