谷粒商城-高级-67 -商城业务-订单服务-登录拦截

一、环境搭建

订单环境创建细节请参考购物车环境搭建方法，谷粒商城-高级-61 -商城业务-购物车-环境搭建，引入相关的依赖和修改配置。

需要引入的依赖：

• 1、引入 thymeleaf
• 2、引入redis
• 3、引入SpringSession
• 4、引入 devtools

gulimall-order/pom.xml

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

    <!-- redis -->
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

    <!-- 整合SpringSession完成session共享问题,使用redis作为session存储 -->
    <dependency>
      <groupId>org.springframework.session</groupId>
      <artifactId>spring-session-data-redis</artifactId>
    </dependency>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-devtools</artifactId>
      <scope>runtime</scope>
      <optional>true</optional>
    </dependency>

修改配置：
gulimall-order/src/main/resources/application.yml

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://192.168.10.10:3306/gulimall_oms
    driver-class-name: com.mysql.cj.jdbc.Driver
  #  配置nacos注册中心
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
  application:
    name: gulimall-order
  thymeleaf:
    cache: false   # 测试期间关掉缓存
  redis:
    host: 192.168.10.10
    prot: 6379
  session:
    store-type: redis  # Session store type,SpringSession整合，使用redis作为session存储
mybatis-plus:
  mapper-location: classpath:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto  # id主键自增
server:
  port: 9000
  servlet:
    session:
      timeout: 30m  # Session timeout,SpringSession整合

创建session配置：
com/atguigu/gulimall/order/config/GulimallSessionConfig.java

package com.atguigu.gulimall.order.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.session.web.http.CookieSerializer;
import org.springframework.session.web.http.DefaultCookieSerializer;

/**
 * @author: kaiyi
 * @create: 2020-09-09 17:05
 */
@EnableRedisHttpSession //除了在启动类开启，这里也可以开启
@Configuration
public class GulimallSessionConfig {

  /**
   * 子域名共享设置及session名自定义
   * @return
   */
  @Bean
  public CookieSerializer cookieSerializer(){
    DefaultCookieSerializer defaultCookieSerializer = new DefaultCookieSerializer();

    defaultCookieSerializer.setDomainName("gulimall.com");   // 设置作用域
    defaultCookieSerializer.setCookieName("GULISESSION");     // 设置session名

    return defaultCookieSerializer;
  }

  /**
   * 默认序列化转为JSON存储
   *
   * @return
   */
  @Bean
  public RedisSerializer<Object> springSessionDefaultRedisSerializer(){
    return new GenericJackson2JsonRedisSerializer();
  }
}

二、登录拦截

参照 gulimall-cart 购物车中的拦截验证，未登录的用户直接跳转到登录页面。

gulimall-order/xxx/order/interceptor/LoginUserInterceptor.java

package com.atguigu.gulimall.order.interceptor;

import com.atguigu.common.constant.AuthServerConstant;
import com.atguigu.common.vo.MemberResponseVo;
import org.springframework.stereotype.Component;
import org.springframework.util.AntPathMatcher;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.PrintWriter;

/**
 * @Description: 登录拦截器
 * @author: kaiyi
 * @createTime: 2020-09-12 19:21
 **/

@Component
public class LoginUserInterceptor implements HandlerInterceptor {

    public static ThreadLocal<MemberResponseVo> loginUser = new ThreadLocal<>();

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        String uri = request.getRequestURI();
        AntPathMatcher antPathMatcher = new AntPathMatcher();
        boolean match = antPathMatcher.match("/order/order/status/**", uri);
        boolean match1 = antPathMatcher.match("/payed/notify", uri);
        if (match || match1) {
            return true;
        }

        //获取登录的用户信息
        MemberResponseVo attribute = (MemberResponseVo) request.getSession().getAttribute(AuthServerConstant.LOGIN_USER);

        if (attribute != null) {
            //把登录后用户的信息放在ThreadLocal里面进行保存
            loginUser.set(attribute);

            return true;
        } else {
            //未登录，返回登录页面
            response.setContentType("text/html;charset=UTF-8");
            PrintWriter out = response.getWriter();
            out.println("<script>alert('请先进行登录，再进行后续操作！');location.href='http://auth.gulimall.com/login.html'</script>");
            // session.setAttribute("msg", "请先进行登录");
            // response.sendRedirect("http://auth.gulimall.com/login.html");
            return false;
        }
    }

    @Override
    public void postHandle(
        HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {

    }
}
