分析：上述日志有两处问题

1. org.jboss.vfs.VFS 没找到
2. Reader entry 乱码

由上面两处问题大致可以猜测是由于指定的VFS没有找，mybatis启用了默认的DefaultVFS，然后由于DefaultVFS的内部逻辑，从而导致了reader entry乱码。
所以解决问题的切入点有两个。1: org.jboss.vfs.VFS 2:修改DefaultVFS

1. 追加org.jboss.vfs.VFS相关的依赖
   由于我是用maven来构建的项目，所以直接加入下面的依赖

     <dependency>
      <groupId>org.jboss</groupId>
      <artifactId>jboss-vfs</artifactId>
      <version>3.2.15.Final</version>
    </dependency>

2. 看了一下，貌似不用解决，这些乱码是编译后的class文件的一部分，本来就没啥意义，无所谓。不信你可以尝试用文本编辑器打开任意class文件。都长那样
