spring boot:swagger3文档展示分页和分栏的列表数据（swagger 3.0.0 / spring boot 2.3.3）

一，什么情况下需要展示分页和分栏的数据的文档?

    分页时，页面上展示的是同一类型的列表的数据，如图:

   

    分栏时,每行都是一个列表，而且展示的数据类型也可能不同

    

   这也是两种常用的数据返回形式

三，配置文件说明：

1,pom.xml

        <!-- swagger3 begin -->

四，java代码说明

1，Swagger3Config.java

@EnableOpenApi

swagger的通用配置

2,HomeController.java

@Api(tags = "首页信息管理")
@Controller
@RequestMapping("/home")
public class HomeController {

    @Operation(summary = "首页详情")
    @GetMapping("/home")
    @ResponseBody
    public RestResult<PageResult<RowResult<Goods,Ad>>> home() {
        //整体的返回
        RestResult res = new RestResult();

        //一行用到的list
        List<Goods> rowList = new ArrayList();
        Goods goodsone = new Goods();
        goodsone.setGoodsId(3L);
        goodsone.setGoodsName("电子书");
        goodsone.setSubject("学python,学ai");
        goodsone.setPrice(new BigDecimal(60));
        goodsone.setStock(10);
        rowList.add(goodsone);

        Goods goodstwo = new Goods();
        goodstwo.setGoodsId(4L);
        goodstwo.setGoodsName("蓝牙音箱");

        List<Goods> resList = new ArrayList();

        Goods goodsone = new Goods();
        goodsone.setGoodsId(3L);
        goodsone.setGoodsName("电子书");
        goodsone.setSubject("学python,学ai");

        return new RestResult(ResponseCode.SUCCESS.getCode(), ResponseCode.SUCCESS.getMsg(), data);
    }

    public static RestResult success(Integer code,String msg) {
        return new RestResult(code, msg, null);
    }

    //返回出错数据
    public static RestResult error(ResponseCode code) {
        return new RestResult(code.getCode(), code.getMsg(), null);
    }

    public Integer getCode() {
        return code;
    }
    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }
    public void setMsg(String msg) {
        this.msg = msg;
    }

    public T getData() {
