<!--通过命名空间和对应id检索对应的sql语句-->

项目结构简单如图，

简单测试代码;

UserController.java

packagecom.aries.mo.Controller;

importorg.springframework.beans.factory.annotation.Autowired;

importorg.springframework.stereotype.Controller;

importorg.springframework.ui.Model;

importorg.springframework.web.bind.annotation.RequestMapping;

importorg.springframework.web.bind.annotation.RequestParam;

importcom.aries.mo.service.UserService;

@Controller

@RequestMapping(value="/user")

publicclassUserController{

@Autowired

privateUserServiceuserService;

@RequestMapping(value="/text")

publicStringTestUser(Modelmodel/*,@RequestParam("userName")StringuserName*/){

model.addAttribute("userName",userService.getName());

return"userShow";

}

}

UserDao.java

packagecom.aries.mo.dao;

importjava.util.List;

importorg.mybatis.spring.support.SqlSessionDaoSupport;

importorg.springframework.stereotype.Repository;

importcom.aries.mo.entity.User;

@Repository

publicclassUserDaoextendsSqlSessionDaoSupport{

@SuppressWarnings("unchecked")

publicList<User>getUesr(){

returngetSqlSession().selectList("userDao.getUesr");
