本教程需要有MyBatisPlus基础
后端技术：SpringBoot2.7.9、MyBatisPlus3.5.1、MySQL8
前端技术：Vue2.5.16+axios、BootStrap3.3.7文章来源：https://www.toymoban.com/news/detail-839430.html
一、后端开发
1.1、配置MyBatisPlus
1.1.1、在pom.xml中添加依赖
<!-- Spring&SpringMVC -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 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>
<version>1.18.20</version>
</dependency>
<!-- mysql-connector -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.32</version>
</dependency>
1.1.2、在application.yml中配置数据源
server:
port: 8070
spring:
datasource:
type: com.zaxxer.hikari.HikariDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.01:3306/test_plus?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true
username: root
password: 123456
mybatis-plus:
type-aliases-package: demo.entity
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
global-config:
db-config:
table-prefix: t_
id-type: auto
mapper-locations: classpath:mappers/*.xml
1.1.3、在启动类中配置分页插件
package demo;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@SpringBootApplication
@Configuration
@MapperScan("demo.mapper")
public class Demo {
/** 配置分页插件*/
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
return interceptor;
}
public static void main(String[] args) {
SpringApplication.run(Demo.class);
}
}
1.2、后台开发
1.2.1、SQL脚本
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for t_article
-- ----------------------------
DROP TABLE IF EXISTS `t_article`;
CREATE TABLE `t_article` (

COMMIT;
-- ----------------------------
-- Table structure for t_channel
-- ----------------------------
DROP TABLE IF EXISTS `t_channel`;
CREATE TABLE `t_channel` (
`id` bigint(20) NOT NULL,

INSERT INTO `t_channel` (`id`, `channel_name`, `create_time`) VALUES (2, '头七', '2023-02-27 17:27:14');
COMMIT;
SET FOREIGN_KEY_CHECKS = 1;
1.2.2、实体Article
package demo.entity;
import lombok.Data;
@Data
public class Article {
private Long id;
private String title;
private String logo;
private String descn;
private String createTime;
private Long cid;
}
1.2.3、ArticleMapper.java
package demo.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import demo.entity.Article;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
@Repository
public interface ArticleMapper extends BaseMapper<Article> {
Page<Article> selectByPage(Page<Article> page, @Param("title") String title);
}
1.2.4、ArticleMapper.xml
<?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="demo.mapper.ArticleMapper">
<select id="selectByPage" resultType="Article">
select * from t_article where title like '%${title}%'
</select>
</mapper>
1.2.5、ArticleController
package demo.controller;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import demo.entity.Article;
import demo.mapper.ArticleMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@CrossOrigin
public class ArticleController {
@Autowired
private ArticleMapper articleMapper;
@GetMapping("/list")
public Page<Article> findAll(Long pageIndex, Long pageSize){
Page<Article> page = articleMapper.selectPage(new Page(pageIndex, pageSize), null);
return page;
}
@GetMapping("/list_custom")
public Page<Article> customFindAll(Long pageIndex, Long pageSize, String title){
Page<Article> page = articleMapper.selectByPage(new Page(pageIndex, pageSize), title);
return page;
}
}
二、前端开发
2.1、html代码
<div class="container" id="app">
<table class="table table-striped">
<caption>文章列表</caption>
<thead>
<tr>
<th align="center">编号</th>
<th align="center">标题</th>
<th align="center">描述</th>
<th align="center">发布时间</th>
<th align="center">操作</th>
</tr>
</thead>
<tbody>
<tr v-for="art in articleList">
<td>{{art.id}}</td>
<td>{{art.title}}</td>
<td>{{art.descn}}</td>
<td>{{art.createTime}}</td>
<td align="center">
<button class="btn btn-link" style="margin-right: 10px;">修改</button>
<button class="btn btn-link">删除</button>
</td>
</tr>
</tbody>
</table>
<ul class="pagination" v-for="p in pageCnt">
<li v-if="p == pageIndex" class="active"><a href="#" @click="doGo(p)">{{p}}</a></li>
<li v-else="p == pageIndex"><a href="#" @click="doGo(p)">{{p}}</a></li>
</ul>
</div>
2.2、Js代码
<script>
new Vue({
el: '#app',
data: {
articleList: null,
//用于分页
pageIndex: 1, //页码
pageSize: 3, //每页显示的条数
pageTotal: 0, //总条数
pageCnt: 0 //总页数
},
methods: {
requestArticleList(){
axios.get("http://localhost:8070/list?pageIndex="+this.pageIndex+"&pageSize="+this.pageSize).then(res => {
console.log(res.data)
this.articleList = res.data.records
this.pageCnt = res.data.pages
this.pageTotal = res.data.total
this.pageIndex = res.data.current
this.pageSize = res.data.size
})
},
doGo(p){
this.pageIndex = p
this.requestArticleList()
}
},
created: function () {
this.requestArticleList()
}
})
</script>
