为什么mabatis的配置sqlMapConfigxml文件中文注释报错

Error如下:

sqlMapConfog.xml文件如下：

   
       
           
           
           
               
               
               
               
           
       
   
     
       
       
   

Reson:

是ＸＭＬ文件的中文注释引起的异常，去掉配置文件中的中文注释或改用英文描述则可以通过
后来发现是配置文件中采用：单数个中文或字母后跟单数个中文再用“-->”结束注释（中文后不加空格）行得通。
如：、 ，对此异常可以采用在左右边界加上空格的方式解决。 如像这样

也可能是配置文件sqlMapConfig.xml或映射文件中http://www.ibatis.com/dtd/sql-map-config-2.dtd"> 含有多个空格的原因
