瑞吉外卖和苍穹外卖区别
对于苍穹外卖，前端代码部分都是导入的，没有进行编写开发。都是对于接口的分析以及服务端代码的开发
苍穹外卖作为瑞吉的增强版，在他原有的基础上新增了SpringTask任务定时（对于待接单和待支付的功能做定时处理），JWT替换Session来实现登录验证，阿里云OSS（实现对象存储，即菜品和套餐图片存储【需要另外学具体的知识】），POI（实现Excel报表的下载），HttpClient（实现微信支付时的信息发送），WebSocket（实现来单提醒和用户催单），
PageHelper（做分页处理）

1.7. 配置文件
数据库映射表名驼峰法mybatis配置
server: port: 8080 spring: application: name: reggie_take_out datasource: druid: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/reggie?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true username: root password: root mybatis-plus: configuration: #在映射实体或者属性时，将数据库中表名和字段名中的下划线去掉，按照驼峰命名法映射 map-underscore-to-camel-case: true log-impl: org.apache.ibatis.logging.stdout.StdOutImpl global-config: db-config: id-type: ASSIGN_ID
2. 创建一个新项目步骤
此处使用的技术栈为MP 实现基础的CRUD
所有创建步骤为
2.1. Mapper
@Mapper public interface EmployeeMapper extends BaseMapper<Employee> { //继承MP 实现常见的crud方法 }
2.2. impl以及service
public interface EmployeeService extends IService<Employee> { }
@Service public class EmployeeServiceImpl extends ServiceImpl<EmployeeMapper, Employee> implements EmployeeService { }
2.3. controller
@RestController @Slf4j @RequestMapping("/employee") public class EmployeeController { @Autowired private EmployeeService employeeService; }
3. 登录
前端调用后端接口
主要看 code，data.msg 前后端保持一致
4. 响应结果类
@Data public class R<T> { private Integer code; //编码：1成功，0和其它数字为失败 private String msg; //错误信息 msg是错误信息 //展示在error方法中 private T data; //数据 返回给前端的数据 在controller中是<>泛型表示 private Map map = new HashMap(); //动态数据 public static <T> R<T> success(T object) { R<T> r = new R<T>(); r.data = object; r.code = 1; return r; } public static <T> R<T> error(String msg) { R r = new R(); r.msg = msg; r.code = 0; return r; } public R<T> add(String key, Object value) { this.map.put(key, value); return this; } }
5. 过滤器 登录拦截处理
需要在mian类中添加个@ServletComponentScan注解
package cn.nanchengyu.reggie.filter; import cn.nanchengyu.reggie.common.R; import com.alibaba.fastjson.JSON; import lombok.extern.slf4j.Slf4j; import org.springframework.util.AntPathMatcher; import javax.servlet.*; import javax.servlet.annotation.WebFilter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; /** * ClassName: LoginCheckFilter * Package: cn.nanchengyu.reggie.filter * Description: * * @Author 南城余 * @Create 2024/1/15 18:06 * @Version 1.0 */ @WebFilter(filterName = "loginCheckFilter",urlPatterns = "/*") @Slf4j public class LoginCheckFilter implements Filter{ //路径匹配器，支持通配符 public static final AntPathMatcher PATH_MATCHER = new AntPathMatcher(); @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) servletRequest; HttpServletResponse response = (HttpServletResponse) servletResponse; //1、获取本次请求的URI String requestURI = request.getRequestURI();// /backend/index.html log.info("拦截到请求：{}",requestURI); //定义不需要处理的请求路径 String[] urls = new String[]{ "/employee/login", "/employee/logout", //后端请求 "/backend/**", "/front/**" }; //2、判断本次请求是否需要处理 boolean check = check(urls, requestURI); //3、如果不需要处理，则直接放行 if(check){ log.info("本次请求{}不需要处理",requestURI); filterChain.doFilter(request,response); return; } //4、判断登录状态，如果已登录，则直接放行 if(request.getSession().getAttribute("employee") != null){ log.info("用户已登录，用户id为：{}",request.getSession().getAttribute("employee")); filterChain.doFilter(request,response); return; } log.info("用户未登录"); //5、如果未登录则返回未登录结果，通过输出流方式向客户端页面响应数据 response.getWriter().write(JSON.toJSONString(R.error("NOTLOGIN"))); } /** * 路径匹配，检查本次请求是否需要放行 * @param urls * @param requestURI * @return */ public boolean check(String[] urls,String requestURI){ for (String url : urls) { boolean match = PATH_MATCHER.match(url, requestURI); if(match){ return true; } } return false; } }
6. 全局异常处理类
@ControllerAdvice(annotations = {RestController.class, Controller.class}) //表示在这加了这两个注解的类上生效 @ResponseBody //返回json数据 @Slf4j public class GlobalExceptionHandler { @ExceptionHandler(SQLIntegrityConstraintViolationException.class) public R<String> exceptionHandler(SQLIntegrityConstraintViolationException ex) { log.error("异常：{}", ex.getMessage()); if (ex.getMessage().contains("Duplicate entry")) { String[] split = ex.getMessage().split(""); //表示根据空格分割错误信息 表示数组的索引值所在位置 String msg = split[2] + "已存在"; return R.error(msg); } return R.error("未知错误"); } }
