基于spring boot的缓存Cache

1、在springboot的 Application上开启缓存注解

@SpringBootApplication
@EnableCaching //开启基于注解的缓存
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

2、创建controller、service、dao层结构

3、在类或者方法里面使用注解

@Service
public class UserServiceImpl extends BaseServiceImpl<UserMapper, User> implements IUserService {


    @Override
    @Cacheable(cacheNames = "user") //开启命名为user的缓存
    public String colUserName(Long id) {
        User user = new User();
        user.setId(id);
        return (String) column("name",user);;
    }

    @Override
    @CacheEvict(cacheNames = "user",allEntries = true)  //删除命名为user的全部缓存
    public void deleteUserCache() {

    }
}
