- 在进行MyBatis与spring问题
-
在进行MyBatis与spring整合时不管是使用映射器方法还是纯的XML方法都出现下列问题，查找资料和官方文档都感觉代码与逻辑没有错！！求解答！
下面是是使用映射器方法的spring配置文件beans.xml的内容：其中UserMapper的代码是：
package xx.xx;
import java.util.List;
import org.apache.ibatis.annotations.Select;
import com.yiwei.po.User;
public interface UserMapper {
@Select("select * from user")
public List findAllUser();@Select("select * from user where id=#{id}") public User findUserById(int id);}
UserDAOImpl中的代码是：
public class UserDAOImpl implements UserDAO {
private UserMapper userMapper;
public UserMapper getUserMapper() {
return userMapper;
}public void setUserMapper(UserMapper userMapper) { this.userMapper = userMapper; } @Override public List<User> findAllUsers() { // TODO Auto-generated method stub List<User> users = userMapper.findAllUser(); return users; }}
下面是测试出现的错误：

每次只要一执行这句：ApplicationContext application = new ClassPathXmlApplicationContext("beans.xml");就会报上述错误！！
请高手解答！！！
