问题解决，这是由于配置了两个连接池，一个是druid连接池，一个是Redis的缓存连接。而spring加载完druid连接池后就不加载了，导致Redis的连接配置读取不进来。
解决办法：在加载连接池的配置加上ignore-unresolvable="true"，两个连接池都要加上
比如：
spring-mybatis.xml配置文件中
<< span="">context:property-placeholder location="classpath:druid-config.properties" ignore-unresolvable="true"/>
spring-redis.xml配置文件中
```
<< span="">context:property-placeholder location="classpath:redis.properties" ignore-unresolvable="true"/>
```

当你使用多个配置文件的时候，一定要在配置文件的标签后面加上ignore-unresolvable="true"，这样才会读取所有的配置文件，不然会找不到。
