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; /** * <p> * * </p> * * @author lqh * @since 2018-05-25 */ @TableName("tb_student") public class Student extends Model<Student> { 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; /** * <p> * Mapper 接口 * </p> * * @author lqh * @since 2018-05-25 */ public interface StudentMapper extends BaseMapper<Student> { }
mapperXml-->StudentMapper.xml(这个文件要放到src/main/resources/mapper)
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.warrior.mapper.StudentMapper"> <!-- 通用查询映射结果 --> <resultMap id="BaseResultMap" type="com.warrior.entity.Student"> <id column="id" property="id" /> <result column="stu_name" property="stuName" /> <result column="stu_number" property="stuNumber" /> <result column="age" property="age" /> </resultMap> <!-- 通用查询结果列 --> <sql id="Base_Column_List"> id, stu_name AS stuName, stu_number AS stuNumber, age </sql> </mapper>
.service-->IStudentService.java
package com.warrior.service; import com.warrior.entity.Student; import com.baomidou.mybatisplus.service.IService; /** * <p> * 服务类 * </p> * * @author lqh * @since 2018-05-25 */ public interface IStudentService extends IService<Student> { }
.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; /** * <p> * 服务实现类 * </p> * * @author lqh * @since 2018-05-25 */ @Service public class StudentServiceImpl extends ServiceImpl<StudentMapper, Student> implements IStudentService { }
.controler-->StudentController.java
package com.warrior.controler; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /** * <p> * 前端控制器 * </p> * * @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; /** * <p> * 前端控制器 * </p> * * @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"; } }
