修复mapper-locations配置为根路径时，文件修改后热加载失败的问题

[zhfeng1]

修复mapper-locations配置为项目根路径时，同时扫描到target和/src/main/resources下的同一个Mapper，导致mapperLocations中存在两个相同的Mapper路径，继而文件修改后热加载失败的问题

[zhfeng1]

您好，我遇到了一个问题，如题所示。最终报错是找不到MappedStatement。猜测问题点应该是两个一样的xml，第一次重新加载时loadedResources清空了，但是第二次重新加载是loadedResources中已经有这个xml了，所以xmlMapperBuilder::parse方法中就没有重新放到Configuration中。

有完整的异常堆栈信息吗，是在本地还是在服务器上

是在本地遇到的。下面是堆栈，数据已脱敏，日志中也可以看到有两条：mapperLocation reload success：xxx，但只有一条mybatis xml file has changed

加我微信waynaqua我给你远程看看吧，这个堆栈看不出来。
