vue分页+spring boot +分页插件pagehelper

后端代码

pom.xml中加入分页插件依赖

 <!-- 分页插件 -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.3</version>
        </dependency

page工具类

@Data
public class PageBean implements Serializable {
   
   
    private long total;//总页数
    private List<ViewMaterial> rows;//记录数
    public PageBean(long total,List<ViewMaterial> rows){
   
   
        this.total = total;
        this.rows = rows;
    }
}

其中ViewMaterial是一个实体类

Mapper接口层:MaterialMapper.java

Page<ViewMaterial> findByPage();

实现接口:MaterialMapper.xml

<select id="findByPage" resultType="com.gzdh.shangchao.model.ViewMaterial">
    select * FROM ViewMaterial ORDER BY pkid
  </select>

服务接口层:MaterialServer.java

PageBean findByPage(int pageCode, int pageSize);

实现服务接口层:MaterialServerImpl.java

public PageBean findByPage(int pageCode,int pageSize){
   
   
        //使用Mybatis分页插件
        PageHelper.
