mybatis-plus+springboot+vue+element-ui实现分页

第一步导入依赖

<!--     分页组件   -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>5.2.0</version>
        </dependency>
        <!--        mybatis-plus-->
<!-- https://mvnrepository.com/artifact/com.baomidou/mybatisplus-spring-boot-starter -->
            <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.2.0</version>
        </dependency>

然后导入前端element-ui组件+html代码

    <script src="https://unpkg.com/element-ui/lib/index.js">script>

后端代码

mybatis-plus配置文件

import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

//mybatis-plus分页插件
@Configuration
@ConditionalOnClass(value = {PaginationInterceptor.class})
public class MybatisPlusConfig {

    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        return paginationInterceptor;
    }
}

mapper层

public interface InventoryMapper extends BaseMapper<Inventory> {
    //分页
    public Page<Inventory> findByPageService(int pageCode, int pageSize);
}

service层

public interface InventoryService extends IService<Inventory> {
    //分页
    public Page<Inventory> findByPageService(int pageCode, int pageSize);
}

serviceImpl层

@Service
public class InventoryServiceImpl extends ServiceImpl<InventoryMapper, Inventory> implements InventoryService{
  @Resource
    InventoryMapper inventoryMapper;

    @Override
    public Page<Inventory> findByPageService(int pageCode, int pageSize) {
        //1.创建Page对象，传入两个参数：当前页和每页显示记录数
        Page<Inventory> page = new Page<Inventory>(pageCode,pageSize);
        //2.将分页查询到的所有数据封装到Page对象中
        inventoryMapper.selectPage(page,null);
        return page;
    }
}

最后controller层

    //    分页
    @RequestMapping(value = "/pagehelper/{pageCode}/{pageSize}",method = RequestMethod.GET)
    @ResponseBody
    public Page<Inventory> findByPage(@PathVariable(value = "pageCode") int pageCode, @PathVariable(value = "pageSize") int pageSize) {
        System.out.println(pageCode+"...."+pageSize);
        Page<Inventory> pageInfo = inventoryService.findByPageService(pageCode, pageSize);
//        System.out.println(pageInfo);
        return pageInfo;
    }
