配置完成后，写一个简单的用户登录操作:
@Controller public class UserController { @Autowired private IUserService service; @RequestMapping(path="/login") public String login(String username,String password,Model m) { User user = service.login(username, password); m.addAttribute("user", user); return "success"; } }
@Service public class UserServiceImpl implements IUserService { @Autowired private UserMapper mapper; @Override public User login(String username, String password) { //参数验证是否为空 //参数判断--》账号，密码是否正确 return mapper.getUserByUsername(username); } }
<mapper namespace="com.login.dao.UserMapper"> <select id="getUserByUsername" resultType="com.login.entity.User"> SELECT * FROM user WHERE username = #{username} </select> </mapper>
然后启动tomcat:
使用maven整合spring+springmvc+mybatis
