控制台报错：org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement 'com.spbt.mapper.EmpeeMapper.selectName'. It's likely that neither a Result Type nor a Result Map was specified.
这个异常是在mapper文件的
所以检查自己的mapper文件：
select username from empee where username=#{username}
select password from empee where username=#{username}
可以发现我的
解决：将parameterType修改为resultType
登录成功：
二、页面没有显示传递的消息
这是LoginController的实现登录代码
RequestMapping("/empee/login")
public String login(@RequestParam("username") String username,
@RequestParam("password") String password,
Model model, HttpSession session){
if (empeeMapper.selectName(username)!=null){
//用户名存在
if (empeeMapper.selectPwdByName(username).equals(password)){
//密码也正确
session.setAttribute("loginEmpee",username);
return "redirect:/main.html";
}else {
model.addAttribute("msg","密码错误");
return "redirect:/index";
}
}else {
model.addAttribute("msg","用户名不存在，请注册");
return "redirect:/index";
}
}
控制台报错：org.apache.ibatis.binding.BindingException: Mapper method 'com.spbt.mapper.EmpeeMapper.insertEmpee' has an unsupported return type: class com.spbt.pojo.Empee
