1.搭建环境

1.1 创建项目

创建项目：exam-student-vue

1.2 添加坐标

<!-- 父工程 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <!-- jar包版本 -->
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>

        <durid.starter.version>1.1.10</durid.starter.version>
    </properties>

    <!-- 导入需要依赖（坐标/jar包）   -->
    <dependencies>

            <version>${pageHelper.starter.version}</version>
        </dependency>
        <!-- mysql驱动 -->

            <version>2.7.0</version>
        </dependency>

    </dependencies>

1.3 拷贝properties文件

#端口号
server.port=8080

#数据库基本配置
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/db3?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=1234

#druid 连接池配置
#驱动
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#初始化连接池大小
spring.datasource.druid.initial-size=1
#最小连接数
spring.datasource.druid.min-idle=1
#最大连接数
spring.datasource.druid.max-active=20
#获取连接时候验证，会影响性能
spring.datasource.druid.test-on-borrow=true

# mybatis
# mybatis.type-aliases-package=com.czxy.domain.base
# mybatis.mapper-locations=classpath:mappers/*.xml
#mapper
mapper.not-empty=false
mapper.identity=MYSQL
#开启驼峰映射
mybatis.configuration.map-underscore-to-camel-case=true
mybatis.mapper-locations=classpath*:mapper/*.xml
#开启log4j打印SQL语句
logging.level.com.czxy.dao=debug

1.4 编写启动类

package com.czxy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author manor
 *  
 */
@SpringBootApplication
public class StudentVueApplication {
    public static void main(String[] args) {
        SpringApplication.run(StudentVueApplication.class, args);
    }
}

1.5 拷贝封装类

1.6 拷贝配置类

2. 基本结构

2.1 初始化数据库

2.1.1 创建数据库

create database db1010;
use db1010;

2.1.2 建表语句

-- 班级表
create table tb_class(
  `c_id` varchar(32) primary key comment '班级ID',
  `c_name` varchar(50) comment '班级名称',
  `desc` varchar(200) comment '班级描述'
);
insert into tb_class(`c_id`,`c_name`,`desc`) values('c001','Java12班','。。。。');
insert into tb_class(`c_id`,`c_name`,`desc`) values('c002','Java34班','。。。。');

# 学生表
create table tb_student(
  s_id varchar(32) primary key comment '学生ID',
  sname varchar(50) comment '姓名',
  age int comment '年龄',
  birthday datetime comment '生日',
  gender char(1) comment '性别',
  c_id varchar(32)
);
alter table tb_student add constraint foreign key (c_id) references tb_class (c_id);

insert into tb_student(`s_id`,`sname`,`age`,`birthday`,`gender`,`c_id`) values('s001','赵三',19,'2001-01-17','1','c001');
insert into tb_student(`s_id`,`sname`,`age`,`birthday`,`gender`,`c_id`) values('s002','钱四',19,'2001-05-16','1','c001');
insert into tb_student(`s_id`,`sname`,`age`,`birthday`,`gender`,`c_id`) values('s003','孙五',18,'2002-03-15','1','c001');
insert into tb_student(`s_id`,`sname`,`age`,`birthday`,`gender`,`c_id`) values('s004','李三',19,'2001-04-14','0','c002');
insert into tb_student(`s_id`,`sname`,`age`,`birthday`,`gender`,`c_id`) values('s005','周四',19,'2001-02-13','0','c002');
insert into tb_student(`s_id`,`sname`,`age`,`birthday`,`gender`,`c_id`) values('s006','王五',18,'2002-06-12','1','c002');

2.2 后端实现：domain、Mapper

2.2.1 班级相关

JavaBean

package com.czxy.domain;

import javax.persistence.Column;
import javax.persistence.Id;
import javax.persistence.Table;

/**
 * @author manor
 *  
 */
@Table(name="tb_class")
public class Classes {
    @Id
    @Column(name="c_id")
    private String cid;

    @Column(name="c_name")
    private String cname;

    @Column(name="`desc`")
    private String desc;

    public String getCid() {
        return cid;
    }

    public void setCid(String cid) {
        this.cid = cid;
    }

    public String getCname() {
        return cname;
    }

    public void setCname(String cname) {
        this.cname = cname;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    @Override
    public String toString() {
        return "Classes{" +
                "cid='" + cid + '\\'' +
                ", cname='" + cname + '\\'' +
                ", desc='" + desc + '\\'' +
                '}';
    }
}

Mapper

package com.czxy.mapper;

import com.czxy.domain.Classes;
import tk.mybatis.mapper.common.Mapper;

/**
 * @author manor
 *  
 */
@org.apache.ibatis.annotations.Mapper
public interface ClassesMapper extends Mapper<Classes> {
}

2.2.2 学生相关

JavaBean

package com.czxy.domain;

import com.fasterxml.jackson.annotation.JsonFormat;

import javax.persistence.Column;
import javax.persistence.Id;
import javax.persistence.Table;
import java.util.Date;

/**
 * @author manor
 *  
 */
@Table(name="tb_student")
public class Student {

    @Id
    @Column(name="s_id")
    private String sid;         //学生ID

    @Column(name="sname")
    private String sname;         //姓名

    @Column(name="age")
    private Integer age;         //年龄

    @Column(name="birthday")
    @JsonFormat(pattern = "yyyy-MM-dd", timezone = "GMT+8")
    private Date birthday;         //生日

    @Column(name="gender")
    private String gender;      //性别

    @Column(name="c_id")
    private String cid;         //班级外键

    private Classes classes;    //班级对象

    public String getSid() {
        return sid;
    }

    public void setSid(String sid) {
        this.sid = sid;
    }

    public String getSname() {
        return sname;
    }

    public void setSname(String sname) {
        this.sname = sname;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getCid() {
        return cid;
    }

    public void setCid(String cid) {
        this.cid = cid;
    }

    public Classes getClasses() {
        return classes;
    }

    public void setClasses(Classes classes) {
        this.classes = classes;
    }

    @Override
    public String toString() {
        return "Student{" +
                "sid='" + sid + '\\'' +
                ", sname='" + sname + '\\'' +
                ", age=" + age +
                ", birthday=" + birthday +
                ", gender='" + gender + '\\'' +
                ", cid='" + cid + '\\'' +
                ", classes=" + classes +
                '}';
    }
}

Mapper

package com.czxy.mapper;

import com.czxy.domain.Student;
import tk.mybatis.mapper.common.Mapper;

/**
 * @author manor
 *  
 */
@org.apache.ibatis.annotations.Mapper
public interface StudentMapper extends Mapper<Student> {

}

3.后端实现

3.1 班级后端

3.1.1 查询所有班级

service

package com.czxy.service;

import com.czxy.domain.Classes;
import com.czxy.domain.Student;
import com.czxy.mapper.ClassesMapper;
import com.czxy.mapper.以上是关于完整的SpringBoot+Vue增删改查(学生管理)的主要内容，如果未能解决你的问题，请参考以下文章
