springboot+vue完成增删改查操作

1、所使用的环境配置：

编译器：IDEA
后台框架：SpringBoot
Mybatis-Plus
数据库：Mysql8.0
数据库工具：Navicat premium
前端框架：Vue Element UI

2、项目简介

这是一个基于SpringBoot和Vue的简单增删改查。

3、代码和配置

项目结构
在这里插入图片描述

3.1 配置文件：

(1) Mybatis-Plus配置文件，实现分页查询：MybatisPlusConfig

@Configuration
public class MybatisPlusConfig {

    /**
     * 新的分页插件,一缓和二缓遵循mybatis的规则,需要设置
     * MybatisConfiguration#useDeprecatedExecutor = false 避免缓存出现问题(该属性会在旧插件移除后一同移除)
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }

}

(2) 跨域配置文件：CorsConfig

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration // 一定不要忽略此注解
public class CorsConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**") // 所有接口
                .allowCredentials(true) // 是否发送 Cookie
                .allowedOrigins("*")// 支持域
                .allowedMethods(new String[]{"GET", "POST", "PUT", "DELETE"}) // 支持方法
                .allowedHeaders("*")
                .exposedHeaders("*");
    }
}

(3) swagger配置文件

@Configuration
@EnableSwagger2 //开启seagger注解驱动
public class SwaggerConfig {

    @Bean
    public Docket docket(){
        Docket docket = new Docket(DocumentationType.SWAGGER_2).groupName("QY163")
                .apiInfo(getInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.hm.controller"))
                .build();
        return docket;
    }

    private ApiInfo getInfo(){
        Contact DEFAULT_CONTACT = new Contact("hm", "http://www.baidu.com", "[email protected]");
        ApiInfo apiInfo=new ApiInfo("QY163心里测试系统API", "QY163心里测试系统API", "1.1.0", "http://www.jd.com",
                DEFAULT_CONTACT, "志远科技", "http://www.aaa.com", new ArrayList<VendorExtension>());
        return apiInfo;
    }
}

(4) mysql 配置

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.url=jdbc:mysql:///work

mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

(5) Result请求返回类

@Data
@NoArgsConstructor
@AllArgsConstructor
@ApiModel(value = "公共json对象")
public class Result {
    @ApiModelProperty(value = "状态码 200正常 500错误")
    private Integer code;

    @ApiModelProperty(value = "消息内容")
    private String msg;

    @ApiModelProperty(value = "数据")
    private Object data;
}

（6）pom.xml配置文件

3.2 代码

1. 实体类
学生实体类

/**

 **/
@Data
@ApiModel(value = "学生实体类")
public class Student implements Serializable {
    /**
     *
     */
    @TableId(type = IdType.AUTO)
    @ApiModelProperty(value = "学生编号")
    private Integer sid;

    /**

    @ApiModelProperty(value = "学生姓名")
    private String sname;

    /**

    @ApiModelProperty(value = "班级编号")
    private Integer cid;

    @TableField(exist = false)

        this.sid = sid;
        this.sname = sname;
        this.age = age;
        this.cid = cid;
    }

    public Student(String sname, Integer age, Integer cid) {
        this.sname = sname;
        this.age = age;
        this.cid = cid;
    }

    private static final long serialVersionUID = 1L;
}

班级实体类

import java.io.Serializable;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;


@Data

    @ApiModelProperty(value = "班级名称")
    private String cname;

    private static final long serialVersionUID = 1L;

2. 定义一个StudentVo来作为条件查询

@ApiModel(value = "接收学生的请求参数")
public class StudentVo {
    @ApiModelProperty(value = "学生编号")
    private String sid;
    @ApiModelProperty(value = "学生的名称")
    private String  sname;

    private String cid;

    public String getSid() {

    }

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

    public String getSname() {
        return sname;
    }

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

    public String getAge() {
        return age;
    }

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

    public String getCid() {
        return cid;
    }

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

    public StudentVo(String sid, String sname, String age, String cid) {
        this.sid = sid;
        this.sname = sname;
        this.age = age;
        this.cid = cid;
    }
}

3.mapper层

StudentMapper

public interface StudentMapper extends BaseMapper<Student> {

    IPage<Student> findByPage(IPage<Student> iPage,@Param("ew") Wrapper<Student> wrapper);

}

ClassMapper

import com.baomidou.mybatisplus.core.mapper.BaseMapper;

import java.util.List;

/**

public interface ClassMapper extends BaseMapper<Class> {

4. Vue工程

4.1在App.vue中添加Student路径

在这里插入图片描述

4.2 main.js中引入axios

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import './plugins/element.js'
import axios from "axios";

Vue.config.productionTip = false
Vue.prototype.axios=axios

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

4.3 index.js

在这里插入图片描述

4.4 Student.vue
