1、項目簡介
1.1、簡介
智慧校園管理系統：主要是以年級、班級為單位，進行老師和學生信息記錄和統計功能。項目采用前后端分離架構思想，前端采用 HTML+CSS+VUE來實現頁面效果展示，后端采用 SpringBoot+MybatisPlus 框架實現數據存儲等服務。存儲層使用高性能的 MySQL，服務器使用 SpringBoot 內置的Tomcat9.x，項目構建工具使用Maven來管理jar包和項目構建。
1.2、項目模塊
1.3、使用的技術
2、環境搭建
2.1、使用 IDEA的 SpringBoot 創建一個Maven項目
設置好包名及存放位置，無需添加其他功能，后面會對 pom.xml 進行改動，其他配置通過 maven 添加即可
2.2、在 pom.xml 導入依賴
為了避免影響其他插件的使用，需要使用較低的 SpringBoot 的版本
這里數據庫用的版本是 mysql5.27版本，根據不同版本導入不同版本的依賴
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><!-- 繼承方式使用SpringBoot --><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.1.RELEASE</version><relativePath/></parent><groupId>cn.xs</groupId><artifactId>myzhxy</artifactId><version>0.0.1-SNAPSHOT</version><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--單元測試啟動器--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- thymeleaf支持--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><!-- mybatis-plus--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.3.1</version></dependency><!-- lombok插件簡化實體類開發 --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!--mysql--><!--<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency>--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.38</version></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-generator</artifactId><version>3.3.1</version></dependency><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.31</version></dependency><!--swagger--><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.7.0</version></dependency><!--swagger ui--><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.7.0</version></dependency><!--swagger2 增強版接口文檔--><dependency><groupId>com.github.xiaoymin</groupId><artifactId>knife4j-spring-boot-starter</artifactId><version>2.0.4</version></dependency><!--開發者工具--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.29</version></dependency><!-- JWT生成Token--><dependency><groupId>io.jsonwebtoken</groupId><artifactId>jjwt</artifactId><version>0.7.0</version></dependency><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.4</version></dependency></dependencies><build><plugins><!--spring boot maven插件 , 可以將項目運行依賴的jar包打到我們的項目中--><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>2.3、準備目錄結構
java目錄下
config : 項目的配置類
controller: 控制層
mapper : 持久層接口
pojo : 實體類
service: 服務層
util: 工具類包
resources目錄下
mapper :持久層映射文件
public/upload:文件上傳目錄
static: 靜態資源目錄
application.yml :SpringBoot核心配置文件
2.4、配置?application.yaml
server:port: 8080 #指定當前項目啟動的端口號 spring:#解決SpringBoot2.6.0與swagger沖突問題【原因是在springboot2.6.0中將SpringMVC 默認路徑匹配策略從AntPathMatcher 更改為PathPatternParser，導致出錯，解決辦法是切換回原先的AntPathMatcher】mvc:pathmatch:matching-strategy: ant_path_matcher#配置數據源datasource:#配置數據源類型type: com.zaxxer.hikari.HikariDataSource#配置數據庫連接屬性driver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://localhost:3308/atguigu_zhxy_db?characterEncoding=utf-8&useSSL=falseusername: rootpassword: roothikari:connection-test-query: SELECT 1connection-timeout: 60000idle-timeout: 500000max-lifetime: 540000maximum-pool-size: 12minimum-idle: 10pool-name: GuliHikariPoolthymeleaf:#模板的模式，支持 HTML, XML TEXT JAVASCRIPTmode: HTML5#編碼 可不用配置encoding: UTF-8#開發配置為false,避免修改模板還要重啟服務器cache: false#配置模板路徑，默認是templates，可以不用配置prefix: classpath:/static/jackson:# 時間格式date-format: yyyy-MM-dd HH:mm:ss# 時區time-zone: GMT+8servlet:#設置文件上傳上限multipart:# 單個文件最大大小max-file-size: 10MB# 多個文件總共最大大小max-request-size: 100MB mybatis-plus:configuration:#添加日志支持log-impl: org.apache.ibatis.logging.stdout.StdOutImplmapper-locations: classpath*:/mapper/**/*.xml2.5、準備分頁插件的配置類
@Configuration @MapperScan("cn.xs.myzhxy.mapper") public class Myconfig {/** 分頁插件* */public PaginationInterceptor paginationInterceptor(){PaginationInterceptor paginationInterceptor = new PaginationInterceptor();//paginationInterceptor.setlimit(你的最大單頁限制數量,默認500,小于0 eg：-1不受限制);return paginationInterceptor;} }2.6、準備 swagger2 的配置類
訪問 localhost:端口號/swagger-ui.html，即可查看接口文檔
只有有 ?Api 相關的注解才會生成
@Api 標注在類上，示例：@Api(tags = "年級控制器")
@ApiOperation 標注在方法上，示例：@ApiOperation("(批量)刪除年級信息")
@ApiParam 標注在方法參數上，示例：@ApiParam("要刪除的年級信息的id的JSON集合")
@RequestBody List<Integer> ids
（部分內容可自定義修改，固定模板）
@Configuration @EnableSwagger2 public class Swagger2Config {@Beanpublic Docket webApiConfig(){//添加head參數startList<Parameter> pars = new ArrayList<>();ParameterBuilder tokenPar = new ParameterBuilder();tokenPar.name("userId").description("用戶ID").defaultValue("1").modelRef(new ModelRef("string")).parameterType("header").required(false).build();pars.add(tokenPar.build());ParameterBuilder tmpPar = new ParameterBuilder();tmpPar.name("userTempId").description("臨時用戶ID").defaultValue("1").modelRef(new ModelRef("string")).parameterType("header").required(false).build();pars.add(tmpPar.build());//添加head參數endreturn new Docket(DocumentationType.SWAGGER_2).groupName("webApi").apiInfo(webApiInfo()).select()//可以測試請求頭中：輸入token// 有 ApiOperation 注解才生成//.apis(RequestHandlerSelectors.withClassAnnotation(ApiOperation.class))// 掃描的基礎包.apis(RequestHandlerSelectors.basePackage("cn.xs.myzhxy.controller"))//過濾掉admin路徑下的所有頁面//.paths(Predicates.and(PathSelectors.regex("/sms/.*")))//過濾掉所有error或error.*頁面//.paths(Predicates.not(PathSelectors.regex("/error.*"))).build().globalOperationParameters(pars);}private ApiInfo webApiInfo(){return new ApiInfoBuilder().title("網站-API文檔").description("本文檔描述了網站微服務接口定義").version("1.0").contact(new Contact("xiaoshuang", "http://xiaoshuang.com", "s1791584877@163.com")).build();}private ApiInfo adminApiInfo(){return new ApiInfoBuilder().title("后臺管理系統-API文檔").description("本文檔描述了后臺管理系統微服務接口定義").version("1.0").contact(new Contact("xiaoshuang", "http://xiaoshuang.com", "s1791584877@163.com")).build();}}2.7、準備 util 下的工具類

public class JwtHelper {private static long tokenExpiration = 24 * 60 * 60 * 1000;private static String tokenSignKey = "123456";//生成token字符串public static String createToken(Long userId, Integer userType) {String token = Jwts.builder().setSubject("YYGH-USER").setExpiration(new Date(System.currentTimeMillis() + tokenExpiration)).claim("userId", userId) // .claim("userName", userName).claim("userType", userType).signWith(SignatureAlgorithm.HS512, tokenSignKey).compressWith(CompressionCodecs.GZIP).compact();return token;}//從token字符串獲取useridpublic static Long getUserId(String token) {if (StringUtils.isEmpty(token)) return null;Jws<Claims> claimsJws = Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token);Claims claims = claimsJws.getBody();Integer userId = (Integer) claims.get("userId");return userId.longValue();}//從token字符串獲取userTypepublic static Integer getUserType(String token) {if (StringUtils.isEmpty(token)) return null;Jws<Claims> claimsJws= Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token);Claims claims = claimsJws.getBody();return (Integer) (claims.get("userType"));}//從token字符串獲取userNamepublic static String getUserName(String token) {if (StringUtils.isEmpty(token)) return "";Jws<Claims> claimsJws= Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token);Claims claims = claimsJws.getBody();return (String) claims.get("userName");}//判斷token是否有效public static boolean isExpiration(String token) {try {boolean isExpire = Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token).getBody().getExpiration().before(new Date());//沒有過期，有效，返回falsereturn isExpire;} catch (Exception e) {//過期出現異常，返回truereturn true;}}/*** 刷新Token* @param token* @return*/public String refreshToken(String token) {String refreshedToken;try {final Claims claims = Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token).getBody();refreshedToken = JwtHelper.createToken(getUserId(token), getUserType(token));} catch (Exception e) {refreshedToken = null;}return refreshedToken;}public static void main(String[] args) { // String token = JwtHelper.createToken(1L, "lucy"); // System.out.println(token); // System.out.println(JwtHelper.getUserId(token)); // System.out.println(JwtHelper.getUserName(token));} }2.7.3、解析request請求中的 token口令的工具AuthContextHolder
public class AuthContextHolder {//從請求頭token獲取useridpublic static Long getUserIdToken(HttpServletRequest request) {//從請求頭tokenString token = request.getHeader("token");//調用工具類Long userId = JwtHelper.getUserId(token);return userId;}//從請求頭token獲取namepublic static String getUserName(HttpServletRequest request) {//從header獲取tokenString token = request.getHeader("token");//jwt從token獲取usernameString userName = JwtHelper.getUserName(token);return userName;} }2.7.4、MD5加密工具類
public final class MD5 {/*** 將明文轉為密文* @param strSrc 明文* @return 密文*/public static String encrypt(String strSrc) {try {char hexChars[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8','9', 'a', 'b', 'c', 'd', 'e', 'f' };byte[] bytes = strSrc.getBytes();MessageDigest md = MessageDigest.getInstance("MD5");md.update(bytes);bytes = md.digest();int j = bytes.length;char[] chars = new char[j * 2];int k = 0;for (int i = 0; i < bytes.length; i++) {byte b = bytes[i];chars[k++] = hexChars[b >>> 4 & 0xf];chars[k++] = hexChars[b & 0xf];}return new String(chars);} catch (NoSuchAlgorithmException e) {e.printStackTrace();throw new RuntimeException("MD5加密出錯！！+" + e);}}}2.7.5、響應結果類型碼枚舉
@Getter public enum ResultCodeEnum {SUCCESS(200,"成功"),FAIL(201, "失敗"),SERVICE_ERROR(2012, "服務異常"),ILLEGAL_REQUEST( 204, "非法請求"),PAY_RUN(205, "支付中"),ARGUMENT_VALID_ERROR(206, "參數校驗錯誤"),LOGIN_ERROR(207, "用戶名或密碼錯誤"),LOGIN_AUTH(208, "未登陸"),PERMISSION(209, "沒有權限"),SECKILL_NO_START(210, "秒殺還沒開始"),SECKILL_RUN(211, "正在排隊中"),SECKILL_NO_PAY_ORDER(212, "您有未支付的訂單"),SECKILL_FINISH(213, "已售罄"),SECKILL_END(214, "秒殺已結束"),SECKILL_SUCCESS(215, "搶單成功"),SECKILL_FAIL(216, "搶單失敗"),SECKILL_ILLEGAL(217, "請求不合法"),SECKILL_ORDER_SUCCESS(218, "下單成功"),COUPON_GET(220, "優惠券已經領取"),COUPON_LIMIT_GET(221, "優惠券已發放完畢"),LOGIN_CODE(222,"長時間未操作,會話已失效,請刷新頁面后重試!"),CODE_ERROR(223,"驗證碼錯誤!"),TOKEN_ERROR(224,"Token無效!");private Integer code;private String message;private ResultCodeEnum(Integer code, String message) {this.code = code;this.message = message;} }2.7.6、JSON響應結果格式封裝類

這里展示admin，其他操作一樣
@Data @AllArgsConstructor @NoArgsConstructor @TableName("tb_admin") public class Admin {@TableId(value = "id", type = IdType.AUTO)private Integer id;private String name;private Character gender;private String password;private String email;private String telephone;private String address;private String portraitPath; // 頭像圖片路徑 } @Mapper public interface AdminMapper extends BaseMapper<Admin> { } public interface AdminService extends IService<Admin> { } @Service("adminServiceImpl") @Transactional public class AdminServiceImpl extends ServiceImpl<AdminMapper, Admin> implements AdminService { } @RestController @RequestMapping("/sms/adminController") public class AdminController { }完成以上搭建后，應該可以實現對首頁的訪問
