器材管理

和员工管理基本一致，就不赘述，展示代码为主

新增器材

表设计：

字段名

数据类型

说明

备注

id

bigint

主键

自增

name

varchar(32)

器材名字

img

varchar(255)

图片

number

BIGINT

器材数量

comment

VARCHAR(99)

器材描述

status

Int

器材状态

1正常 0锁定

create_time

Datetime

创建时间

update_time

datetime

最后修改时间

借走/归还

create_user

bigint

创建人id

update_user

bigint

最后修改人id

借走或者归还

sql语句


CREATE TABLE equipment (id BIGINT AUTO_INCREMENT PRIMARY KEY,  -- 自增主键name VARCHAR(32) NOT NULL,  -- 器材名字，不允许为空number BIGINT NOT NULL default 1,  -- 器材数量:默认为1comment VARCHAR(99) , -- 器材描述status INT NOT NULL DEFAULT 1,  -- 器材状态，默认为1（正常），0表示锁定create_time DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,  -- 创建时间，默认为当前时间update_time DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,  -- 最后修改时间，默认为当前时间，并在每次更新时自动更新create_user BIGINT NOT NULL,  -- 创建人id，不允许为空update_user BIGINT NOT NULL,  -- 最后修改人id，不允许为空FOREIGN KEY (create_user) REFERENCES student(id),FOREIGN KEY (update_user) REFERENCES student(id)
-- 注意：这里假设create_user和update_user是用户ID，您需要确保这些ID在相应的用户表中存在

实体类

创建数据库的器材的封装实体类

sems-pojo/src/main/java/com/ljc/entity/Equipment.java

package com.ljc.entity;import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;
import java.security.SecureRandom;
import java.time.LocalDateTime;@Data
@Builder  //可是使用builder方式来定义数据
@NoArgsConstructor  //无参构造器
@AllArgsConstructor  //有参构造器
public class Equipment implements Serializable {private static final long serialVersionUID = 1L;//告诉Java虚拟机（JVM）这个类的对象是可以被序列化的。private Long id;private String name;//图片private String img;//器材数量private Long number;//器材描述private String comment;private Integer status;private LocalDateTime createTime;private LocalDateTime updateTime;private Long createUser;private Long updateUser;}

接收前端的数据，创建实体类DTO

sems-pojo/src/main/java/com/ljc/dto/EquipmentDTO.java

package com.ljc.dto;import lombok.Data;import java.io.Serializable;@Data
public class EquipmentDTO implements Serializable {//器材idprivate Long id;//器材名字private String name;//图片private String img;//器材数量private Long number;//器材描述private String comment;

OSS云上传图片

实现步骤：

1). 定义OSS相关配置

sems-server/src/main/resources/application.yml

server:port: 8080spring:profiles:active: devmain:allow-circular-references: truedatasource:druid:driver-class-name: ${ljc.datasource.driver-class-name}url: jdbc:mysql://${ljc.datasource.host}:${ljc.datasource.port}/${ljc.datasource.database}?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=trueusername: ${ljc.datasource.username}password: ${ljc.datasource.password}mybatis:#mapper配置文件mapper-locations: classpath:mapper/*.xmltype-aliases-package: com.ljc.entityconfiguration:#开启驼峰命名map-underscore-to-camel-case: truelogging:level:com:sky:mapper: debugservice: infocontroller: infoljc:jwt:# 设置jwt签名加密时使用的秘钥admin-secret-key: kussm# 设置jwt过期时间admin-ttl: 7200000# 设置前端传递过来的令牌名称admin-token-name: tokenalioss:bucket-name: ${ljc.alioss.bucket-name}access-key-secret: ${ljc.alioss.access-key-secret}access-key-id: ${ljc.alioss.access-key-id}endpoint: ${ljc.alioss.endpoint}

sems-server/src/main/resources/application-dev.yml

ljc:datasource:driver-class-name: com.mysql.cj.jdbc.Driverhost: localhostport: 3306database: semsusername: rootpassword: 8888alioss:endpoint: oss-cn-hangzhou.aliyuncs.comaccess-key-id: LTAI5tBt5pkXempSC5vPAocuaccess-key-secret: XDMFmdEjA6c8Tl5a4xCg4dF4avoJtMbucket-name: kussmcx

2). 读取OSS配置

sems-common/src/main/java/com/ljc/properties/AliOssProperties.java

package com.ljc.properties;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;@Component
@ConfigurationProperties(prefix = "ljc.alioss")
@Data
public class AliOssProperties {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;}

3). 生成OSS工具类对象

sems-server/src/main/java/com/ljc/config/OssConfiguration.java

package com.ljc.config;import com.ljc.properties.AliOssProperties;
import com.ljc.utils.AliOssUtil;
import com.ljc.utils.AliOssUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration//配置类特有的注释
@Slf4j
public class OssConfiguration {@Bean@ConditionalOnMissingBeanpublic AliOssUtil aliOssUtil(AliOssProperties aliOssProperties){log.info("开始创建阿里云文件上传工具类对象：{}",aliOssProperties);return new AliOssUtil(aliOssProperties.getEndpoint(),aliOssProperties.getAccessKeyId(),aliOssProperties.getAccessKeySecret(),aliOssProperties.getBucketName());}
}

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

package com.ljc.utils;import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.OSSException;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.extern.slf4j.Slf4j;import java.io.ByteArrayInputStream;@Data
@AllArgsConstructor
@Slf4j
public class AliOssUtil {private String endpoint;private String accessKeyId;private String accessKeySecret;private String bucketName;/*** 文件上传** @param bytes* @param objectName* @return*/public String upload(byte[] bytes, String objectName) {// 创建OSSClient实例。OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);try {// 创建PutObject请求。ossClient.putObject(bucketName, objectName, new ByteArrayInputStream(bytes));} catch (OSSException oe) {System.out.println("Caught an OSSException, which means your request made it to OSS, "+ "but was rejected with an error response for some reason.");System.out.println("Error Message:" + oe.getErrorMessage());System.out.println("Error Code:" + oe.getErrorCode());System.out.println("Request ID:" + oe.getRequestId());System.out.println("Host ID:" + oe.getHostId());} catch (ClientException ce) {System.out.println("Caught an ClientException, which means the client encountered "+ "a serious internal problem while trying to communicate with OSS, "+ "such as not being able to access the network.");System.out.println("Error Message:" + ce.getMessage());} finally {if (ossClient != null) {ossClient.shutdown();}}//文件访问路径规则 https://BucketName.Endpoint/ObjectNameStringBuilder stringBuilder = new StringBuilder("https://");stringBuilder.append(bucketName).append(".").append(endpoint).append("/").append(objectName);log.info("文件上传到:{}", stringBuilder.toString());return stringBuilder.toString();}
}

4). 定义文件上传接口

在sems-server/src/main/java/com/ljc/controller/admin/CommonController.java

package com.ljc.controller.admin;import com.ljc.utils.AliOssUtil;
import com.ljc.constant.MessageConstant;
import com.ljc.result.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;
import java.util.UUID;/*** 通用接口，上传文件（图片）*/
@RestController
@RequestMapping("/admin/common")
@Slf4j
@Api(tags = "通用接口")
public class CommonController {@Autowiredprivate AliOssUtil aliOssUtil;@ApiOperation("文件上传")@PostMapping("/upload")public Result<String> upload(MultipartFile file){log.info("文件上传：{}" + file);try {//objectname使用UUID来生成//1.获取原始文件名称String originalFilename = file.getOriginalFilename();//2.截取文件的后缀String suffix = originalFilename.substring(originalFilename.lastIndexOf("."));//获取文件.之后的部分//3.构建新文件名称String newFilename = UUID.randomUUID().toString() + suffix;String filePash =  aliOssUtil.upload(file.getBytes(), newFilename);//调用upload的方法return Result.success(filePash);//调用aliossUtil修改后的数据，这样才能将访问路劲改为oss云的；} catch (IOException e) {log.info(MessageConstant.UPLOAD_FAILED + e);}return Result.error(MessageConstant.UPLOAD_FAILED);//文件上传失败的常量；}}
