IBatis.Net系列 - Invalid SqlMap.config document. cause :Cannot load schema for the namespace ''

今天,我将前天写的代码重新编译,竟出现
Invalid SqlMap.config document. cause :Cannot load schema for the namespace '' - Could not find file "C:\WINDOWS\system32\SqlMapConfig.xsd"
的错误.
最后在http://shanyou.cnblogs.com/archive/2005/10/17/256720.aspx
找到了解决方法.
1、IBatisNet的配置文件的格式采用了标准的XML的命名空间：
   原来的providers.config 文件
      <?xml version="1.0" encoding="utf-8" ?>

            <providers>
               <clear/>
                 <provider
                     ……
             </providers>
   更改为
   <?xml version="1.0" encoding="utf-8"?>
          <providers xmlns=" http://ibatis.apache.org/providers" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance">
            <clear/>
             <provider
                     ……
        </providers>
  原来的SqlMap.config文件

 <?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="SqlMapConfig.xsd">
……
</sqlMapConfig>
更改为
<?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig xmlns=" http://ibatis.apache.org/dataMapper" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance">
原来的PO.xml文件
<?xml version="1.0" encoding="UTF-8" ?>

<sqlMap namespace="Sequence" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="SqlMap.xsd">
……
</sqlMap>
更改为
<?xml version="1.0" encoding="UTF-8" ?>
<sqlMap namespace="Admin" xmlns=" http://ibatis.apache.org/mapping" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance">
……
</sqlMap>
