java之redis篇(spring-data-redis整合)

 

redis的知识：官网

1，利用spring-data-redis整合

项目使用的pom.xml：

除了log部分，只有一个spring core 和 spring-data-redis了

项目文件目录结构：

 

applicationContext.xml：

1，context:property-placeholder 标签用来导入properties文件。从而替换${redis.maxIdle}这样的变量。

2，context:component-scan 是为了在com.x.redis.dao报下的类能够实用spring的注解注入的方式。

3，事实上我们只需要把JedisPoolConfig配数来就好了，接下来就是spring的封装了。所以直接看UserDAOImpl的实现就明白了。
