注意：几乎不直接调用 SqlSession 的任何方法.
需要注意的是：Spring的事务处理的是：runtimeException:而编译时异常是没有处理的，所以需要
自己单独设置RollBackFor=Exception.class
eg:FileInputStream input = new FileInputStream(new File("D:\\2323\23.txt"))
例：简单的对数据库的操作
EmployeeMapper.java:
public interface EmployeeMapper {
public employee getEmployeeById(int id);
}
EmployeeMapper.xml:
<select id="getEmployeeById" parameterType="Integer" resultType="com.neuedu.Bean.employee">
select id,last_name,email,gender
from tbl_employee
where id = #{id}
</select>
测试类：
public class smTest {
@Test
public void test() {
ApplicationContext ioc =new ClassPathXmlApplicationContext("Spring.xml");
EmployeeMapper bean = ioc.getBean(EmployeeMapper.class);
employee employee = bean.getEmployeeById(10);
System.out.println(employee);
}
｝
输出结果为：
employee [id=10, lastName=hah, gender=1, email=email]
