1、项目简介

1.1、简介

智慧校园管理系统:主要是以年级、班级为单位,进行老师和学生信息记录和统计功能。项目采用前后端分离架构思想,前端采用 HTML+CSS+VUE来实现页面效果展示,后端采用 SpringBoot+MybatisPlus 框架实现数据存储等服务。存储层使用高性能的 MySQL,服务器使用 SpringBoot 内置的Tomcat9.x,项目构建工具使用Maven来管理jar包和项目构建。

1.2、项目模块

1.3、使用的技术

尚硅谷智慧校园 —— 1、简介及环境搭建_第2张图片

2、环境搭建

2.1、使用 IDEA的 SpringBoot 创建一个Maven项目

设置好包名及存放位置即可,无需添加其他功能,后面会对 pom.xml 大改,其他功能通过 maven 添加即可

2.2、在 pom.xml 导入依赖

为了避免影响其他插件的使用,需要使用较低的 SpringBoot 的版本

由于我的数据库是 mysql5,导入的依赖也应该是 5.x 版本的

2.3、准备目录结构

  1. java目录下

    1. config : 项目的配置类

    2. controller: 控制层

    3. mapper : 持久层接口

    4. pojo : 实体类

    5. service: 服务层

    6. util: 工具类包

  2. resources目录下

    1. mapper :持久层映射文件

    2. public/upload:文件上传目录

    3. static: 静态资源目录

    4. application.yml :SpringBoot核心配置文件

尚硅谷智慧校园 —— 1、简介及环境搭建_第3张图片

 2.4、配置 application.yaml

server:
  port: 8080  #指定当前项目启动的端口号
spring:
  #解决SpringBoot2.6.0与swagger冲突问题【原因是在springboot2.6.0中将SpringMVC 默认路径匹配策略从AntPathMatcher 更改为PathPatternParser,导致出错,解决办法是切换回原先的AntPathMatcher】
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher
  #配置数据源
  datasource:
    #配置数据源类型
    type: com.zaxxer.hikari.HikariDataSource
    #配置数据库连接属性
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/zhxy_db?characterEncoding=utf-8&useSSL=false   #&serverTimezone=GMT%2B8
    username: root
    password: zyj123
    hikari:
      connection-test-query: SELECT 1
      connection-timeout: 60000

      max-lifetime: 540000
      maximum-pool-size: 12
      minimum-idle: 10
      pool-name: GuliHikariPool
  thymeleaf:

mybatis-plus:
  configuration:
    #添加日志支持
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
  mapper-locations: classpath*:/mapper/**/*.xml

2.5、准备分页插件的配置类

@Configuration
@MapperScan("com.zyj.myzhxy.mapper")
public class MyConfig {

    @Bean
    public PaginationInterceptor paginationInterceptor(){
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        return paginationInterceptor;
    }

}

2.6、准备 swagger2 的配置类

若想查看,需访问 localhost:端口号/swagger-ui.html

只有有  Api 相关的注解才会生成

@Api 标注在类上,示例:@Api(tags = "年级控制器")

@ApiOperation 标注在方法上,示例:@ApiOperation("(批量)删除年级信息")

@ApiParam 标注在方法参数上,示例:@ApiParam("要删除的年级信息的id的JSON集合") @RequestBody List ids

import com.google.common.base.Predicates;

                .select()
                //可以测试请求头中:输入token
                // 有 ApiOperation 注解才生成
                //.apis(RequestHandlerSelectors.withClassAnnotation(ApiOperation.class))
                // 扫描的基础包
                .apis(RequestHandlerSelectors.basePackage("com.zyj.myzhxy.controller"))
                //过滤掉admin路径下的所有页面
                //.paths(Predicates.and(PathSelectors.regex("/sms/.*")))
                //过滤掉所有error或error.*页面
                //.paths(Predicates.not(PathSelectors.regex("/error.*")))
                .build()
                .globalOperationParameters(pars);

    }



    private ApiInfo webApiInfo(){

        return new ApiInfoBuilder()
                .title("网站-API文档")
                .description("本文档描述了网站微服务接口定义")
                .version("1.0")
                .contact(new Contact("atguigu", "http://atguigu.com", "[email protected]"))
                .build();
    }

    private ApiInfo adminApiInfo(){

        return new ApiInfoBuilder()
                .title("后台管理系统-API文档")
                .description("本文档描述了后台管理系统微服务接口定义")

                .build();

}

2.7、准备 util 下的工具类

2.7.1、验证码图片工具类

import java.awt.*;

}

2.7.2、token口令生成工具 JwtHelper

package com.zyj.myzhxy.util;

/**
 * @Author zhang
 * @Date 2022/4/17 - 23:18
 * @Version 1.0
 */
import io.jsonwebtoken.*;
import org.springframework.util.StringUtils;

import java.util.Date;

public class JwtHelper {
    // 一天的毫秒数
    private static long tokenExpiration = 24*60*60*1000;
    // 后缀信息,用于增加保密性
    private static String tokenSignKey = "123456";

    //生成token字符串(根据tokenExpiration和tokenSignKey)
    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)

        Claims claims = claimsJws.getBody();
        Integer userId = (Integer)claims.get("userId");
        return userId.longValue();
    }

    //从token字符串获取userType
    public static Integer getUserType(String token) {
        if(StringUtils.isEmpty(token)) return null;
        Jws claimsJws
                = Jwts.parser().setSigningKey(tokenSignKey).parseClaimsJws(token);
        Claims claims = claimsJws.getBody();

        Claims claims = claimsJws.getBody();
        return (String)claims.get("userName");
    }

    //判断token是否有效
    public static boolean isExpiration(String token){
        try {
            boolean isExpire = Jwts.parser()
                    .setSigningKey(tokenSignKey)

        }
    }


    /**

//        System.out.println(JwtHelper.getUserId(token));
//        System.out.println(JwtHelper.getUserName(token));
    }
}

2.7.3、解析request请求中的 token口令的工具AuthContextHolder

import javax.servlet.http.HttpServletRequest;

public class AuthContextHolder {

    //从请求头token获取userid
    public static Long getUserIdToken(HttpServletRequest request) {
        //从请求头token
        String token = request.getHeader("token");
        //调用工具类
        Long userId = JwtHelper.getUserId(token);
        return userId;
    }

    //从请求头token获取name
    public static String getUserName(HttpServletRequest request) {
        //从header获取token
        String token = request.getHeader("token");
        //jwt从token获取username
        String userName = JwtHelper.getUserName(token);
        return userName;
    }
}

2.7.4、MD5加密工具类

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;


public final class MD5 {

    /**
     * 将明文转为密文
     * @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];
            }

2.9、根据数据表准备pojo、mapper、controller、service及其实现类

这里只写 admin,其他类似

@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;  // 头像图片路径
}
@Mapper
public interface AdminMapper extends BaseMapper {
}
public interface AdminService extends IService {
}
@Service("adminServiceImpl")
@Transactional
public class AdminServiceImpl extends ServiceImpl implements AdminService {
}
@RestController
@RequestMapping("/sms/adminController")
public class AdminController {
}

3、测试访问首页的问题:数据库版本不一致

完成以上搭建后,应该可以实现对首页的访问,但我这里失败了。后来发现是因为数据库版本的不一致的问题。

由于我的 MySQL 版本为 5.7,这里需要在 pom.xml 中更改导入的数据库驱动版本

        
            mysql
            mysql-connector-java
            5.1.38
        

application.yaml 中数据库的配置也要与 5.7 版本的格式对应

    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/zhxy_db?characterEncoding=utf-8&useSSL=false   #&serverTimezone=GMT%2B8
    username: root
    password: zyj123
