如果是spring boot项目，一定要在pom.xml文件中引入以下依赖包：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

package com.gdss.ruralrevitalization.model;
 
import lombok.Data;
import javax.validation.constraints.Max;
 
 
//分页实体类
@Data
public class PageModel {
    @Max(value = 1)
    private int current;  //当前页
    @Max(value = 100)
    private int size; //数量
}

Controller类，通过BindingResult查看是否有报错信息，需要写在@Valid参数后面

@GetMapping("/getList")
    public ResultModel getList(@Valid PageModel page,BindingResult result){
        ResultModel resultModel=new ResultModel();
        IPage<UserViewBaseModel> lstEntity =administrativeAreasService.getListPage(searchModel,new Page(page.getCurrent(), page.getSize()));
        resultModel.setData(lstEntity);
        return  resultModel;
}
