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;

<!-- spring boot redis -->
<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");
}
}
