再父子模块开发中,
因为redis缓存具有通用性,所以放在单独的模块中
当其他模块引用该模块时,通过web.xml中的这种配置进行配置classpath*
代表加载本模块以及其引用jar包中的classpath下的配置文件
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
使用
@Autowired
private RedisTemplate redisTemplate;
注意在增删改时,删除redis相关的缓存,因为在后台界面常见增删改,都会进行列表的重新刷新,所以对于一些特殊格式的缓存,在后台重新读取列表的方法中进行删缓存的操作
实际的一个应用场景:

做上面这种效果时,将品牌数据,规格数据缓存在redis中,因为这种数据不经常发生变化,这种情况比较好的做法是,在操作这些数据的service层中,在增删改方法里添加加入更新缓存的方法,
