- struts构建文件上传
这是第一个类,与表中的信息相对应(当然如果只是简单的文件上传可以不用这样麻烦,之所以这样作是因为传到数据库里容易管理) package tester.business.maitain; public class Trainplan { private int p_id; private String p_title; private int post_index; private String issue_time; private String issuer; private String p_content; private String p_accessory; public int getP_id() { return p_id; } public void setP_id(int p_id) { this.p_id = p_id; }
