java – MyBatis 3.0.1插入问题

mapper xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"    
                 "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="bap.persistance.interfaces.ArticleMapper">
 <insert id="insertTestA">
  insert into test_a ( cookie ) values( 'tomek pilot');
 </insert>
</mapper>

mapper java文件：

public interface ArticleMapper {
 void insertTestA();
}

映射器实现：

String resource = "bap/persistance/MyBatis_xml/MyBatisConfig.xml";

....

... 
public void createArticle( Article article ) throws IOException {
  Reader reader = Resources.getResourceAsReader(resource);
  SqlSessionFactory sqlSessionFactory = 
          new SqlSessionFactoryBuilder().build(reader);
  SqlSession session = sqlSessionFactory.openSession();

  try{
   ArticleMapper mapper = session.getMapper(ArticleMapper.class);
   mapper.insertTestA();
  } catch( Exception e ){
   e.printStackTrace();
  } finally{
   session.close();
  }
  return article.getId();
 }
...

... line omitted for brevity.

使用中的表格：

CREATE TABLE test_a
(
  cookie text
)
WITH (OIDS=FALSE);

我正在尝试使用mybatis 3.0.1,spring 3.0.3,postgresql 8.3(使用postgresql-8.4-701.jdbc3.jar)运行它

我相信所有样板设置都已正确设置(我可以对另一个表执行精选.

我手动测试了inser并且它工作得很好(插入test_a(cookie)值(‘some stuff’);)

由于某种原因插入不执行,没有堆栈跟踪显示:-(

任何提示将非常感激:-)
