13-springboot集成Redis
Spring boot 集成 Redis 的步骤如下:
1、在pom.xml中配置相关的jar依赖;
<!-- 加载spring boot redis包 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
2、在Springboot核心配置文件application.properties中配置redis连接信息:
spring.redis.host=ip
spring.redis.port=port
spring.redis.password=password
3、配置了上面的步骤,Spring boot将自动配置RedisTemplate,在需要操作redis的类中注入redisTemplate;
在使用的类中注入:
@Autowired
private RedisTemplate redisTemplate;
@Autowired
private RedisTemplate<String, String> redisTemplate;
@Autowired
private RedisTemplate<Object, Object> redisTemplate;
spring Boot帮我们注入的redisTemplate类,泛型里面只能写 <String, String>、<Object, Object>或者什么都不写;
比如说写成如下:(会报错)
@Autowired
private RedisTemplate<String, Object> redisTemplate;
@Service
public class RedisServiceImpl implements RedisService {
/**
* 注入即可使用
*/
@Autowired
private RedisTemplate redisTemplate;
@PostConstruct
public void setRedisTemplate(){
redisTemplate.setKeySerializer(new StringRedisSerializer());
}
@Override
public void cache() {
redisTemplate.opsForValue().set("springbootkey","THIS IS VALUE");
}
}
