生成的文件如下,只要将对应文件拷到项目对应包即可:

下面把对应类展示出来:
.entity-->Student.java

package com.warrior.entity;

import com.baomidou.mybatisplus.enums.IdType;
import com.baomidou.mybatisplus.annotations.TableId;
import com.baomidou.mybatisplus.annotations.TableField;
import com.baomidou.mybatisplus.activerecord.Model;
import com.baomidou.mybatisplus.annotations.TableName;
import java.io.Serializable;

/**
 * 

* *

* * @author lqh * @since 2018-05-25 */ @TableName("tb_student") public class Student extends Model { private static final long serialVersionUID = 1L; @TableId(value="id", type= IdType.AUTO) private Integer id; @TableField("stu_name") private String stuName; @TableField("stu_number") private String stuNumber; private Integer age; public Integer getId() { return id; } public Student setId(Integer id) { this.id = id; return this; } public String getStuName() { return stuName; } public Student setStuName(String stuName) { this.stuName = stuName; return this; } public String getStuNumber() { return stuNumber; } public Student setStuNumber(String stuNumber) { this.stuNumber = stuNumber; return this; } public Integer getAge() { return age; } public Student setAge(Integer age) { this.age = age; return this; } @Override protected Serializable pkVal() { return this.id; } }


.mapper-->StudentMapper.java

package com.warrior.mapper;

import com.warrior.entity.Student;
import com.baomidou.mybatisplus.mapper.BaseMapper;

/**
 * 

* Mapper 接口 *

* * @author lqh * @since 2018-05-25 */ public interface StudentMapper extends BaseMapper { }


.mapperXml-->StudentMapper.xml(这个文件要放到src/main/resources/mapper)

 





	
	
		
		
		
		
	

    
    
        id, stu_name AS stuName, stu_number AS stuNumber, age
    


.service-->IStudentService.java

 

package com.warrior.service;

import com.warrior.entity.Student;
import com.baomidou.mybatisplus.service.IService;

/**
 * 

* 服务类 *

* * @author lqh * @since 2018-05-25 */ public interface IStudentService extends IService { }



.serviceImpl-->StudentServiceImpl.java

 

package com.warrior.serviceImpl;

import com.warrior.entity.Student;
import com.warrior.mapper.StudentMapper;
import com.warrior.service.IStudentService;
import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;

/**
 * 

* 服务实现类 *

* * @author lqh * @since 2018-05-25 */ @Service public class StudentServiceImpl extends ServiceImpl implements IStudentService { }


.controler-->StudentController.java

 

package com.warrior.controler;

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

/**
 * 

* 前端控制器 *

* * @author lqh * @since 2018-05-25 */ @Controller @RequestMapping("/warrior/student") public class StudentController { }



经过以上六步项目已经搭建完成,下面就是写业务代码了,只需要实现controller即可,下面对StudentController.java进行修改:

 

package com.warrior.controler;

import com.warrior.entity.Student;
import com.warrior.service.IStudentService;
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;

/**
 * 

* 前端控制器 *

* * @author lqh * @since 2018-05-05 */ @Controller @RequestMapping("/warrior/student") public class StudentController { @Autowired IStudentService iStudentService; @RequestMapping("/hello") @ResponseBody public String hello() { //insert Student student = new Student() .setStuName("zhangsan") .setStuNumber("54") .setAge(23); boolean res = iStudentService.insert(student); return res ? "success" : "fail"; } }
