集成validation，为列表接口增加参数校验 l

package com.jiawa.wiki.req;
 
import javax.validation.constraints.Max;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Null;
 
public class PageReq {
 
    /*增加权限校验规则-防止他人恶意对接口进行攻击*/
    @NotNull(message = "【页码】不能为空")
    private int page;
    @NotNull(message = "【页面条数】不能为空")
    @Max(value = 50, message = "【页面条数】不能超过50")
    private int size;
 
 
    public int getPage() {
        return page;
    }
 
    public void setPage(int page) {
        this.page = page;
    }
 
    public int getSize() {
        return size;
    }
 
    public void setSize(int size) {
        this.size = size;
    }
    @Override
    public String toString() {
        return "PageReq{" +
                "page=" + page +
                ", size=" + size +
                '}';
    }
}
