Exception：ClassNotFoundException: org.apache.ibatis.io.Resources

1. servlet中条用DBcon访问sqlMapConfig.xml

import java.io.IOException;
import java.io.InputStream;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;

public class DBcon {
    public static SqlSession getsqlsession() {
        SqlSessionFactory ssf=null;
        try {
            InputStream in = Resources.getResourceAsStream("sqlMapConfig.xml");
            ssf= new SqlSessionFactoryBuilder().build(in);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        SqlSession sqlsession = ssf.openSession();
        return sqlsession;
    }
}

**解决方案：对应jar不可用，但是在测试类是可以实现对数据库的访问，重新更新了下Maven project 并强制重新
下载jar包依赖，问题解决**
