所用的框架为：springmvc+mybatis

改之前的代码：

   controller层：

public class loginController {
	@Autowired
	public loginServiceImpl loginservice;
	@RequestMapping(value="/login")
	 public String login(@Param("name")String username,@Param("password") String password,HttpServletRequest request,
				HttpServletResponse response){
		manager man=loginservice.queryUserByNameAndPassword(name, password);

  mapper.xml:

   	 	select * from manager  where name=#{name,jdbcType=VARCHAR} and password=#{password,jdbcType=VARCHAR} 
 	 
 

问题所在：controller中的方法参数与mapper.xml中的参数类型不对应，将controller中的方法参数写成对象的形式，将各种参数赋给该对象进行传递。

改之后的controller层：

 public String login(@Param("name")String username,@Param("password") String password,HttpServletRequest request,
				HttpServletResponse response){
		
		manager m=new manager();
		m.setName(name);
		m.setPassword(password);
		manager man=loginservice.queryUserByNameAndPassword(m);
