我在阅读MyBatis 3.0.2的xml配置文件时遇到问题。
我必须在Axis2 1.5的Web服务中使用它。我有一个类代码：
public static org.apache.ibatis.session.SqlSessionFactory getSqlMapper () {
org.apache.ibatis.session.SqlSessionFactory sqlMapper;
try {
String resource = "MyBatis.xml";
java.io.Reader reader = org.apache.ibatis.io.Resources.getResourceAsReader(resource);
sqlMapper = new org.apache.ibatis.session.SqlSessionFactoryBuilder().build(reader);
} catch (Exception e) {
// Si hay un error en este punto, no importa cual sea. Será un error irrecuperable del cual
// nos interesará solo estar informados.
// Deberás registrar el error y reenviar la excepción de forma que se te notifique el
// problema de forma inmediata.
e.printStackTrace();
throw new RuntimeException ("Error initializing MyAppSqlConfig class. Cause: " + e);
}
return sqlMapper;
}
MyBatis.xml是配置文件。当我致电getSqlMapper时，在sqlMapper = new org...行中我得到了这个例外：

我在网上看过很多关于这样的错误，但它让我无处可去。类javax.xml.namespace.Qname似乎是一个问题，应该在两个不同的地方定义，但我不知道如何解决它。
任何人都知道解决方案吗？
