先简单说一下我们工程的架构:前端工程是采用react,后端工程采用spring-cloud,里面分为zuul工程和其他功能模块。zuul工程除了提供后端的路由转发,还可以做全局的过滤器,所以我选择在这个工程里面写登陆校验功能。
session配置
这里使用redis存储session信息。
下载依赖,在pom.xml里面加入

配置session存储,在application.yml里面加入

session: store-type: redis timeout: 30 redis: database: 0 host: password: port: 6379 timeout: 300000 |
session超时,在application.yml里面配置timeout貌似没有效果,我们在启动类里面加入超时配置注解
复制代码 代码如下:
@enableredishttpsession(maxinactiveintervalinseconds = 7200, redisflushmode = redisflushmode.immediate)
添加redis类配置,新建一个redisconfig类,然后写入

package com.config; import org.springframework.context.annotation.configuration; @configuration public class redisconfig { public redisconfig() { } } |
过滤器
这里使用zuulfilter,实现了每个http请求都经过这个过滤器,然后通过session中是否存在用户名,判断session是否超时。如果超时就返回错误提示,前端再根据超时的http请求码进行跳转。

这里还需要在启动类中注入这个类

@bean public websecurityfilter accessfilter() { return new websecurityfilter(); } |
登陆的代码
主要就是把前端传来的用户名密码放到session中,并进行校验。如果校验成功,返回登陆成功,否则,返回登陆失败。前端再根据登陆情况做路由跳转。

最后,贴一下启动类的代码
