Property 'mapperLocations' was not specified or no matching resources found org.apache.ibatis.builder.BuilderException: Could not find value method on SQL annotation

这个问题，其实以前也碰到过，并且已经解决。

但是不巧的事又碰到了，看到问题，知道是mapper里面的问题，但看了半天，好像也没有错。

Scanned package: 'com.Xxxx.XX.model' for aliases
Property 'mapperLocations' was not specified or no matching resources found

解决：

问题在于用了时间比较的 >=     <=

这样就会报错，应该用转义的字符。&gt;=     &lt;=

这个与html中的一致。
