springboot整合redis

一、配置pom.xml

<!-- springboot整合redis -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

二、配置application.yml

#redis单服务器配置
spring:
  redis:
    database: 0
    host: localhost
    port: 6379
    pool:
      max-active: 8
      max-wait: -1
      max-idle: 8
      min-idle: 0

三、开启缓存

@SpringBootApplication(scanBasePackages = { "com.wuxi" })
@MapperScan("com.wuxi.dao")
@EnableCaching    // 开启缓存
public class MySpringApplication {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(MySpringApplication.class, args);
    }
}

四、实体类序列化

public class Person implements Serializable {
}

五、使用方法

@Autowired
private UsersMapper usersMapper;
    
@Cacheable(value="findUser")    // key是方法的参数组合
@Override
public Users findUser(String name) {
    System.out.println("从数据库中查询...");
    return usersMapper.findUserByName(name);
}

@Service
public class UsersService {

    @Autowired
    private RedisTemplate<Object, Object> redisTemplate;

    public Users seleectUsers() {
        Users users = (Users) redisTemplate.opsForValue().get("users");
        return users;
    }

    public void insertUsers(String name) {
        Users users = new Users();
        users.setName(name);
        redisTemplate.opsForValue().set("users", users, 10, TimeUnit.SECONDS);
    }
}
