@MapperScan(value="com.demo") 改为 @MapperScan(value="com.demo.*") 试试

dao层：


   package com.demo.dao;



import java.util.List;



import org.apache.ibatis.annotations.Mapper;

import org.springframework.stereotype.Component;

import org.springframework.stereotype.Repository;



import com.demo.model.User;



@Mapper

public interface UserDao {

    public  List<User> selectUser(int id);

}

然后是service层：


 package com.demo.service;



import java.util.List;



import javax.annotation.Resource;



import org.springframework.stereotype.Service;



import com.demo.dao.UserDao;

import com.demo.model.User;



@Service

public class UserService {

  @Resource 

   private UserDao userdao;

  

  public List<User> userSelectService(int id) throws Exception{

	  System.out.println("测试1");

	  List<User> list = userdao.selectUser(id);

	  System.out.println(list);

	  return list;

  }

}

再是Controller层：


 package com.demo.controller;



import java.util.ArrayList;

import java.util.List;



import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;



import com.demo.model.User;

import com.demo.service.UserService;



	@Controller

	@RequestMapping("/")

	public class SpringBootUserController {

		@Autowired

		private UserService userService;

		 /**

	     * 测试查询

	     * @param id

	     * @return

	     */

	    @RequestMapping("/userSelectAction")

	    @ResponseBody

	    public List<User> userSelectAction(int id) throws Exception{

	    	System.out.println("测试2");

	    	List<User> list= userService.userSelectService(id);

	    	System.out.println(list);

	    	return list;

	    }

	    

	    /**

	     * 只是测试

	     * @return

	     */

		@RequestMapping(value="/hello")  

	    @ResponseBody  

	    public String hello() {  

	        return "测试";  

	    }  

}

启动Action:


 package com.demo;







import org.mybatis.spring.annotation.MapperScan;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

import org.springframework.boot.web.servlet.ServletComponentScan;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.scheduling.annotation.EnableScheduling;







@SpringBootApplication // Spring Boot项目的核心注解，主要目的是开启自动配置  

@ComponentScan(basePackages = {"com.demo"})

@MapperScan(value="com.demo")

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})



public class TestController {



	

	  // 在main方法中启动一个应用，即：这个应用的入口  

    public static void main(String[] args) {  

        SpringApplication.run(TestController.class, args);  

    }  

}

# FREEMARKER (FreeMarkerAutoConfiguration)



spring.jpa.database = MYSQL

# Show or not log for each sql query

spring.jpa.show-sql = true

spring.jpa.hibernate.ddl-auto = update

spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy



spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

这个类放的位置是在启动类层的子包里是可以扫描到的。

UserDao这个dao层有错误，估计是你的dao层对应的映射xml文件和UserDao有不匹配的地方
