使用springboot+MybatisPlus+vue实现论文基础管理系统

页面效果如下

分析所需内容

数据库信息如下

t_paper

t_comment

好了 数据库搞定 新建Springboot项目 选择Spring Initializr

pom文件增加引入下面这三个依赖

<!-- mybatis-plus -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.1</version>
        </dependency>
        <!-- lombok -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId> <optional>true</optional>
        </dependency>
        <!-- mysql-connector -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.32</version>
        </dependency>

四层架构 直接新建四个包 controller(控制器) entity(实体类) mapper(映射文件)service(服务层）

在生成的resources中会有application.properties 这边我更加喜欢yml格式 显示的更加的舒服易懂 然后进行配置即可

server:
  port: 8080
spring:
  # 配置数据源信息
  datasource:
    # 配置数据源类型
    type: com.zaxxer.hikari.HikariDataSource
    # 配置连接数据库信息
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/tess01?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true
    username: root（您的数据库用户名）
    password: XXXXX（您的数据库密码）
mybatis-plus:
  type-aliases-package: com.lps.entity
  configuration:
    # 配置MyBatis日志，执行sql的时候，将sql打印到控制台
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
  global-config:
    db-config:
#前缀
      table-prefix: t_
#设置id为雪花算法
      id-type: assign_id
  mapper-locations: classpath:mappers/*.xml

好了 开始整理实体类

Paper.java 因为使用的是雪花算法 Long类型从前台传回来可能会存在精度缺失 您请记得id加上这串注解

@JsonSerialize(using = ToStringSerializer.class)

package com.lps.entity;

import com.baomidou.mybatisplus.annotation.TableField;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import lombok.Data;

@Data
public class Paper {
    @JsonSerialize(using = ToStringSerializer.class)
    private Long id;//编号
    private String title;//主题
    private String author;//作者
    private String paperType;//类型
    private String publishDate;//日期
    private Integer state;//状态
    @TableField(exist = false)
    private Integer cnt;//评论次数
}

HttpResult.java

package com.lps.entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class HttpResult {
    private int code;//返回code
    private String msg;//返回告之情况
    private Object data;//返回数据
    private int total;//行数
}

实体类搞定之后准备开始精进mapper类

PaperMapper.java 接口

package com.lps.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.lps.entity.Paper;

import java.util.List;

/**
 * @author 阿水
 * @create 2023-03-01 10:19
 */
public interface PaperMapper extends BaseMapper<Paper> {
    List<Paper> findAll(Integer pageIndex ,Integer pageSize,String title,String type);

}

<?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.lps.mapper.PaperMapper">

    <select id="findAll" resultType="Paper">
        SELECT
        DISTINCT p.*, (SELECT count(*) FROM t_comment WHERE p_id=c.p_id) AS cnt
        FROM
        t_paper AS p LEFT JOIN t_comment AS c
        ON
        p.id=c.p_id
        <where>
            <if test="title !='null' and title != ''">
                AND title like '%${title}%'
            </if>
            <if test="type !='null' and type != ''">
                AND paper_type=#{type}
            </if>
        </where>
        ORDER BY p.publish_date DESC
        LIMIT #{pageIndex}, #{pageSize}
    </select>

</mapper>

映射mapper文件

整理service层面

IPaperService.java 接口

package com.lps.service;
import com.lps.entity.HttpResult;
import com.lps.entity.Paper;

/**
 * @author 阿水
 * @create 2023-03-01 10:21
 */
public interface IPaperService {
    HttpResult save(Paper paper);
    HttpResult modify(Paper paper);
    HttpResult remove(Long id );
    HttpResult findAll(Integer pageIndex , Integer pageSize, String title, String type);

    HttpResult findById(Long id);
}

PaperServiceImpl.java接口实现类

package com.lps.service.impl;

import com.lps.entity.HttpResult;
import com.lps.entity.Paper;
import com.lps.mapper.PaperMapper;
import com.lps.service.IPaperService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author 阿水
 * @create 2023-03-01 10:26
 */
@Service
public class PaperServiceImpl implements IPaperService {
    @Autowired(required = false)
    private PaperMapper paperMapper;

    @Override
    public HttpResult save(Paper paper) {
        int insert = paperMapper.insert(paper);
        HttpResult httpResult = null;
        if (insert > 0) {
            httpResult = new HttpResult(200, "添加论文成功", null, 0);
        } else {
            httpResult = new HttpResult(500, "添加论文失败", null, 0);
        }
        return httpResult;
    }

    @Override
    public HttpResult modify(Paper paper) {
        int insert = paperMapper.updateById(paper);
        HttpResult httpResult = null;
        if (insert > 0) {
            httpResult = new HttpResult(200, "修改论文成功", null, 0);
        } else {
            httpResult = new HttpResult(500, "修改论文失败", null, 0);
        }
        return httpResult;
    }

    @Override
    public HttpResult remove(Long id) {
        int insert = paperMapper.deleteById(id);
        HttpResult httpResult = null;
        if (insert > 0) {
            httpResult = new HttpResult(200, "删除论文成功", null, 0);
        } else {
            httpResult = new HttpResult(500, "删除论文失败", null, 0);
        }
        return httpResult;
    }

    @Override
    public HttpResult findAll(Integer pageIndex, Integer pageSize, String title, String type) {
        List<Paper> all = paperMapper.findAll((pageIndex - 1) * pageSize, pageSize, title, type);
        HttpResult httpResult = null;
        if (all != null && all.size() > 0) {
            httpResult = new HttpResult(200, "查询论文成功", all, Math.toIntExact(paperMapper.selectCount(null)));
        } else {
            httpResult = new HttpResult(500, "查询论文失败", null, 0);
        }
        return httpResult;
    }

    @Override
    public HttpResult findById(Long id) {
        Paper paper = paperMapper.selectById(id);
        HttpResult httpResult = null;
        if (paper != null) {
            httpResult = new HttpResult(200, "查询论文成功", paper, Math.toIntExact(paperMapper.selectCount(null)));
        } else {
            httpResult = new HttpResult(500, "查询论文失败", null, 0);
        }
        return httpResult;
    }
}

最后

控制层PaperController.java

package com.lps.controller;

import com.lps.entity.HttpResult;
import com.lps.entity.Paper;
import com.lps.service.IPaperService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author 阿水
 * @create 2023-03-01 10:45
 */
@RestController//标识controller类
@RequestMapping("/paper")//访问前缀
@CrossOrigin(origins = "*")//允许跨端访问
public class PaperController {
    @Autowired//自动引入service
    private IPaperService paperService;

    @PostMapping("/save")
    public HttpResult save(@RequestBody Paper paper){
        SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd");
        String dateStr = format.format(new Date());
        paper.setPublishDate(dateStr);
        return  paperService.save(paper);
    }

    @PostMapping("modify")
    public HttpResult modify(@RequestBody Paper paper){
        return paperService.modify(paper);

    }

    @GetMapping("remove")
    public HttpResult remove(Long id){
        return paperService.remove(id);

    }

    @GetMapping("/find_all")//通过 主题、类型 以及分页查询
    public HttpResult findAll(Integer pageIndex ,Integer pageSize,String title,String type){
        return paperService.findAll(pageIndex,pageSize,title,type);
    }

    @GetMapping("/find_by_id")//通过id查找
    public HttpResult findById(Long id){
        return paperService.findById(id);
    }
}

到此 后端配置的结束啦

开始配置前台页面

 在此我们需要导入这些js文件
