springboot项目如何集成多个redis

Spring Boot可以通过配置多个Redis连接池来实现集成多个Redis。具体步骤如下:
1. 在`application.properties`文件中添加多个Redis连接配置,如下所示:
```
# Redis1
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=
# Redis2
spring.redis2.host=127.0.0.1
spring.redis2.port=6380
spring.redis2.password=
```
2. 在`@Configuration`类中创建多个`RedisConnectionFactory`对象,如下所示:
```
@Configuration
public class RedisConfig {
@Autowired
private Environment environment;
@Bean(name = "redis1ConnectionFactory")
public RedisConnectionFactory redis1ConnectionFactory() {
JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
jedisConnectionFactory.setHostName(environment.getProperty("spring.redis.host"));
jedisConnectionFactory.setPort(Integer.parseInt(environment.getProperty("spring.redis.port")));
jedisConnectionFactory.setPassword(environment.getProperty("spring.redis.password"));
return jedisConnectionFactory;
}
@Bean(name = "redis2ConnectionFactory")
public RedisConnectionFactory redis2ConnectionFactory() {
JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
jedisConnectionFactory.setHostName(environment.getProperty("spring.redis2.host"));
jedisConnectionFactory.setPort(Integer.parseInt(environment.getProperty("spring.redis2.port")));
jedisConnectionFactory.setPassword(environment.getProperty("spring.redis2.password"));
return jedisConnectionFactory;
}
}
```
3. 在需要使用Redis的地方使用`@Qualifier`注解指定使用哪个`RedisConnectionFactory`,如下所示:
```
@Autowired
@Qualifier("redis1ConnectionFactory")
private RedisConnectionFactory redis1ConnectionFactory;
@Autowired
@Qualifier("redis2ConnectionFactory")
private RedisConnectionFactory redis2ConnectionFactory;
```
4. 使用`redis1ConnectionFactory`和`redis2ConnectionFactory`创建`RedisTemplate`对象,并使用`@Qualifier`注解指定使用哪个`RedisConnectionFactory`,如下所示:
```
@Bean(name = "redis1Template")
public RedisTemplate redis1Template() {
RedisTemplate redisTemplate = new RedisTemplate();
redisTemplate.setConnectionFactory(redis1ConnectionFactory);
return redisTemplate;
}
@Bean(name = "redis2Template")
public RedisTemplate redis2Template() {
RedisTemplate redisTemplate = new RedisTemplate();
redisTemplate.setConnectionFactory(redis2ConnectionFactory);
return redisTemplate;
}
```
5. 在需要使用Redis的地方使用`@Qualifier`注解指定使用哪个`RedisTemplate`,如下所示:
```
@Autowired
@Qualifier("redis1Template")
private RedisTemplate redis1Template;
@Autowired
@Qualifier("redis2Template")
private RedisTemplate redis2Template;
```
至此,Spring Boot项目就成功集成了多个Redis。在使用时,只需要使用对应的`RedisTemplate`即可。例如,使用`redis1Template`操作Redis1,使用`redis2Template`操作Redis2。
