技术栈

后端技术:SpringBoot2.7.9、MyBatisPlus3.5.1、MySQL8
前端技术:Vue2.5.16+axios、BootStrap3.3.7

一、后端开发

1.1、配置MyBatisPlus

1.1.1、在pom.xml中添加依赖

		org.springframework.bootspring-boot-starter-webcom.baomidoumybatis-plus-boot-starter3.5.1org.projectlomboklombok1.18.20mysqlmysql-connector-java8.0.32

1.1.2、在application.yml中配置数据源

server:port: 8070
spring:datasource:type: com.zaxxer.hikari.HikariDataSourcedriver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://127.0.01:3306/test_plus?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=trueusername: rootpassword: Aa123123.
mybatis-plus:type-aliases-package: demo.entityconfiguration:log-impl: org.apache.ibatis.logging.stdout.StdOutImplglobal-config:db-config:table-prefix: t_id-type: automapper-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*/@Beanpublic 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

COMMIT;-- ----------------------------
-- Table structure for t_channel
-- ----------------------------
DROP TABLE IF EXISTS `t_channel`;
CREATE TABLE `t_channel` (`id` bigint(20) NOT NULL,`channel_name` varchar(50) DEFAULT NULL,`create_time` datetime DEFAULT NULL,PRIMARY KEY (`id`)

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
{Page
selectByPage(Page
page, @Param("title") String title); }

1.2.4、ArticleMapper.xml





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 {@Autowiredprivate ArticleMapper articleMapper;@GetMapping("/list")public Page
findAll(Long pageIndex, Long pageSize){Page
page = articleMapper.selectPage(new Page(pageIndex, pageSize), null);return page;}@GetMapping("/list_custom")public Page
customFindAll(Long pageIndex, Long pageSize, String title){Page
page = articleMapper.selectByPage(new Page(pageIndex, pageSize), title);return page;} }

二、前端开发

2.1、html代码

	
文章列表
编号标题描述发布时间操作
{{art.id}}{{art.title}}{{art.descn}}{{art.createTime}}

2.2、Js代码

	

三、附录

3.1、完整po.m.xml文件
