mybatis配置问题(mybatis config problem)

 我是MyBatis的新手。 
 
 我一直试图在我写的网络服务中配置mybatis，但还没有运气。 
 
 我已经做的是， 
 
 
 
 UserInfoMapper接口 
 
 
 带有mapper命名空间的UserInfoMapper.xml，带有UserInfoMapper接口和一个select 
 
 
 带有typeAlias的mybatis-config.xml，用作UserInfoMapper.xml中的结果类型 
 
 
 datasourceContext.xml中的oracle（我得连接）的dataSource bean 
 
 
 org.mybatis.spring.mapper.MapperScannerConfigurer bean，basePackage指向datasourceContext.xml中的UserInfoMapper接口 
 
 
 sqlSessionFactory bean即。 org.mybatis.spring.SqlSessionFactoryBean，包含我的dataSource和configLocation的属性 
 
 
 userInfoMapper bean即。 在datasourceContext.xml中使用属性mapperInterface（value =“is.simnn.act.web.ngs.persistence.UserInfoMapper”）和sqlSessionFactory属性（ref =“sqlSessionFactory”）的org.mybatis.spring.mapper.MapperFactoryBean 
 
 
 然后在我的applicationContext.xml中我有以下内容， 
 
 
 
 
 
 
<import resource="classpath:META-INF/wsContext.xml" />
<import resource="classpath:META-INF/db/datasourceContext.xml" />
 
 在我的测试用例中，当我调用jaxws：endpoint时，我一直得到NullPointerException，它引导我进入UserInfoMapper接口。 
 
 对我的配置可能出错的任何想法或提示？ 
 
 谢谢，Gunnlaugur 

I'm new to MyBatis.
 
Ive been trying to configure mybatis in a webservice I'm writing but with no luck yet.
 
What I've done already is,
 
 
 
UserInfoMapper interface
 
 
UserInfoMapper.xml with mapper namespace with my UserInfoMapper interface and a select
 
 
mybatis-config.xml with typeAlias to use as result type in UserInfoMapper.xml
 
 
dataSource bean for oracle (I get connected) in datasourceContext.xml
 
 
org.mybatis.spring.mapper.MapperScannerConfigurer bean with basePackage pointing to my UserInfoMapper interface in datasourceContext.xml
 
 
sqlSessionFactory bean ie. org.mybatis.spring.SqlSessionFactoryBean with property for my dataSource and configLocation
 
 
userInfoMapper bean ie. org.mybatis.spring.mapper.MapperFactoryBean with property mapperInterface (value="is.simnn.act.web.ngs.persistence.UserInfoMapper") and sqlSessionFactory property (ref="sqlSessionFactory") in datasourceContext.xml
 
 
then in my applicationContext.xml I have following,
 
 
 
 
 
 
<import resource="classpath:META-INF/wsContext.xml" />
<import resource="classpath:META-INF/db/datasourceContext.xml" />
 
In my test case I keep getting NullPointerException when I call jaxws:endpoint and it leads me to my UserInfoMapper interface.
 
Any idea or hints to what might be wrong with my config?
 
Thanks, Gunnlaugur
