通过插件生成文件如下

testController

package com.mybatis.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.mybatis.model.student;

@Controller
public class TestController {
	   @Autowired  
	    private com.mybatis.dao.studentMapper studentMapper;  
	      
	    @RequestMapping(value = "/nv/test" ,method=RequestMethod.GET)  
	    public ResponseEntity<?>  indexPage() {     
	        student entity = studentMapper.selectByPrimaryKey(1);
	        System.out.println("name is" + entity.getStudent_name());  
			return new ResponseEntity<String>(HttpStatus.OK);
	    } 
}

注意：spring接口如果返回void 没有返回值的时候会去自动寻找接口名的页面

student

package com.mybatis.dao;

import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.mybatis.model.student;
@Repository
public interface studentMapper {
    int deleteByPrimaryKey(Integer student_id);

    int insert(student record);

    int insertSelective(student record);

    student selectByPrimaryKey(Integer student_id);

    int updateByPrimaryKeySelective(student record);

    int updateByPrimaryKey(student record);
}

注意：使用了@Repository
