SpringBootCache.md

Spring CachePut 是Spring自带的缓存、只需要添加注解即可使用

   /**
     * @CachePut缓存新增或更新数据到缓存，其中缓存名称为people，数据key是people的id
     * @param person
     * @return
     */
    @Override
    @CachePut(value = "people",key = "#person.id")
    public Person save(Person person) {
        Person p=personRepository.save(person);
        return p;
    }

    /**
     * @CacheEvict从缓存people删除key为id的数据
     * @param id
     */
    @Override
    @CacheEvict(value = "people")
    public void remove(Long id) {
        personRepository.delete(id);
    }

    /**
     * @cacheable缓存key为person的id数据到people中（如果没有指明key，则方法参数会做为key保存到缓存中）
     * @param person
     * @return
     */
    @Override
    @Cacheable(value="people",key="#person.id")
    public Person findOne(Person person) {
        Person p=personRepository.findOne(person.id);
        return p;
    }
