2.2 导入knife4j相关配置（WebConfig）

2.3 LoginCheckFilter设置不需要处理的请求路径
package com.runa.reggie.filter;import com.alibaba.fastjson.JSON;
import com.runa.reggie.common.BaseContext;
import com.runa.reggie.common.R;
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;@Slf4j
@WebFilter(filterName = "loginCheckFilter", urlPatterns = "/*")
public class LoginCheckFilter implements Filter {// 路径匹配器public static final AntPathMatcher PATH_MATCHER = new AntPathMatcher();@Overridepublic 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// request.getRequestURL()返回的是全路径。// request.getRequestURI()返回的是除去协议，域名（IP+端口号）之后的路由部分。String requestURI = request.getRequestURI();log.info("拦截到请求：【{}】",requestURI);// 定义一些不需要处理的路径String[] urls = new String[]{"/employee/login","/employee/logout","/backend/**","/front/**","/common/**","/user/sendMsg","/user/login","/doc.html","/webjars/**","/swagger-resources","/v2/api-docs"};// 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 -1（员工端） 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，请求url为：【{}】, 用户id为:【 {} 】 ",requestURI,request.getSession().getAttribute("employee"));// 获取ID 塞进线程Long empId = (Long) request.getSession().getAttribute("employee");BaseContext.setCurrentId(empId);filterChain.doFilter(request,response);return;}// 4 -2（移动端） 判断登录状态，如果已登录，则直接放行if(request.getSession().getAttribute("user") != null){log.info("用户已登录，请求url为：【{}】, 用户id为:【 {} 】 ",requestURI,request.getSession().getAttribute("user"));// 获取ID 塞进线程Long userId = (Long) request.getSession().getAttribute("user");BaseContext.setCurrentId(userId);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")));return;}/*** 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;}}// 循环都匹配不上就返回falsereturn false;}
}
2.4 验证
启动服务
http://localhost:8080/doc.html 
2.5 调试接口
这里存在需要登录问题，这里先登录一下，再调试
2.6 下载接口文档
3、常用注解
3.1 Setmeal实体添加注解
package com.runa.reggie.entity;import com.baomidou.mybatisplus.annotation.FieldFill;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import java.io.Serializable;
import java.math.BigDecimal;
import java.time.LocalDateTime;/*** 套餐*/
@Data
@ApiModel("套餐")
public class Setmeal implements Serializable {private static final long serialVersionUID = 1L;@ApiModelProperty("主键")private Long id;//分类id@ApiModelProperty("分类ID")private Long categoryId;//套餐名称@ApiModelProperty("套餐名称")private String name;//套餐价格@ApiModelProperty("套餐价格")private BigDecimal price;//状态 0:停用 1:启用@ApiModelProperty("状态")private Integer status;//编码@ApiModelProperty("编码")private String code;//描述信息@ApiModelProperty("描述信息")private String description;//图片@ApiModelProperty("图片")private String image;@TableField(fill = FieldFill.INSERT)private LocalDateTime createTime;@TableField(fill = FieldFill.INSERT_UPDATE)private LocalDateTime updateTime;@TableField(fill = FieldFill.INSERT)private Long createUser;@TableField(fill = FieldFill.INSERT_UPDATE)private Long updateUser;//是否删除private Integer isDeleted;
}
3.2 R 添加注解
package com.runa.reggie.common;import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import java.util.HashMap;
import java.util.Map;/*** 通用返回结果，服务端响应的数据最终都会封装成此对象* @param <T>*/
@Data
@ApiModel("返回结果")
public class R<T> {@ApiModelProperty("编码")private Integer code; //编码：1成功，0和其它数字为失败@ApiModelProperty("错误信息")private String msg; //错误信息@ApiModelProperty("数据")private T data; //数据@ApiModelProperty("动态数据")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;}}
3.3 SetmealController添加注解
package com.runa.reggie.controller;import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.runa.reggie.common.R;
