java中内部类使用详解

需求

需要在接口数据中传以下格示的入参，在业务上属于同一业务，且复用性不强，所以用内部类的方式去操作，直观和简洁;

主要意见： 还是使用了主类中的公共方法

代码示例

package com.hka.doc.seeyon.budget.entity;

import lombok.Data;

import java.io.Serializable;
import java.util.List;
@Data
public class SeeyonCreatePaymentDocParam implements Serializable {

    private static final long serialVersionUID = 1L;

    String appName;
    SecondDataPojo data;

    public Formson_0188 use0188(){
        return  new Formson_0188();
    }
    public Formmain_0187 use0187(){
        return  new Formmain_0187();
    }
    public FormDetail useDetail(){
        return new FormDetail();
