怎么做網(wǎng)站前端展示型網(wǎng)站有哪些
器材管理
和員工管理基本一致，就不贅述，展示代碼為主
新增器材
表設(shè)計：
| 字段名 | 數(shù)據(jù)類型 | 說明 | 備注 |
| id | bigint | 主鍵 | 自增 |
| name | varchar(32) | 器材名字 | |
| img | varchar(255) | 圖片 | |
| number | BIGINT | 器材數(shù)量 | |
| comment | VARCHAR(99) | 器材描述 | |
| status | Int | 器材狀態(tài) | 1正常 0鎖定 |
| create_time | Datetime | 創(chuàng)建時間 | |
| update_time | datetime | 最后修改時間 | 借走/歸還 |
| create_user | bigint | 創(chuàng)建人id | |
| update_user | bigint | 最后修改人id | 借走或者歸還 |
sql語句
CREATE TABLE equipment (id BIGINT AUTO_INCREMENT PRIMARY KEY, -- 自增主鍵name VARCHAR(32) NOT NULL, -- 器材名字，不允許為空number BIGINT NOT NULL default 1, -- 器材數(shù)量:默認(rèn)為1comment VARCHAR(99) , -- 器材描述status INT NOT NULL DEFAULT 1, -- 器材狀態(tài)，默認(rèn)為1（正常），0表示鎖定create_time DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP, -- 創(chuàng)建時間，默認(rèn)為當(dāng)前時間update_time DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, -- 最后修改時間，默認(rèn)為當(dāng)前時間，并在每次更新時自動更新create_user BIGINT NOT NULL, -- 創(chuàng)建人id，不允許為空update_user BIGINT NOT NULL, -- 最后修改人id，不允許為空FOREIGN KEY (create_user) REFERENCES student(id),FOREIGN KEY (update_user) REFERENCES student(id)
-- 注意：這里假設(shè)create_user和update_user是用戶ID，您需要確保這些ID在相應(yīng)的用戶表中存在

OSS云上傳圖片
實現(xiàn)步驟：
1). 定義OSS相關(guān)配置

2). 讀取OSS配置

3). 生成OSS工具類對象

其中sems-common/src/main/java/com/ljc/utils/AliOssUtil.java
