springboot登陆过滤功能的实现代码

时间:2022-09-25 12:54:41

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

</dependency>
<dependency>
  <groupid>org.springframework.session</groupid>
  <artifactid>spring-session-data-redis</artifactid>
</dependency>

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。

package com.config;
 
import com.netflix.zuul.zuulfilter;
import com.netflix.zuul.context.requestcontext;
import com.ztesoft.cloud.service.staffservice;
import com.ztesoft.cloud.model.user;
import org.springframework.beans.factory.annotation.autowired;
 
import javax.servlet.http.httpservletrequest;
 
public class websecurityfilter extends zuulfilter {
 
  @override
  public string filtertype() {
    return "pre";//前置过滤器
  }
 
  @override
  public int filterorder() {
    return 0;//优先级为0,数字越大,优先级越低
  }
 
  @override
  public boolean shouldfilter() {
    return true;//是否执行该过滤器,此处为true,说明需要过滤
  }
 
 
  @autowired
  private staffservice staffservice;
 
  @override
  public object run() {
    requestcontext ctx = requestcontext.getcurrentcontext();
    httpservletrequest request = ctx.getrequest();
    string querystring = request.getquerystring();
    object username = request.getsession().getattribute("username");
    object password = request.getsession().getattribute("password");
    user user = new user();
    if(username != null) {
      user.setusername(username.tostring());
    }
    if(password != null) {
      user.setpassword(password.tostring());
    }
    boolean verifyresult = this.staffservice.verifyloginuser(user);
    if ((querystring != null && querystring.indexof("tag=process") > -1) || verifyresult) {
      ctx.setsendzuulresponse(true);// 对该请求进行路由
      ctx.setresponsestatuscode(200);
      ctx.set("issuccess", true);// 设值,可以在多个过滤器时使用
      return null;
    } else {
      ctx.setsendzuulresponse(false);// 过滤该请求,不对其进行路由
      ctx.setresponsestatuscode(401);// 返回错误码,应该是401
      ctx.setresponsebody("session is out of time");// 返回错误内容
      ctx.set("issuccess", false);
      return null;
    }
  }
}

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。

@restcontroller
@requestmapping(value = "/system")
public class systemcontroller extends jdkserializationredisserializer implements serializable {
 
  @autowired
  private staffservice staffservice;
 
  @postmapping("login")
  public responseentity<string> login(@requestbody user user, httpsession session) {
    session.setattribute("username", user.getusername());
    session.setattribute("password", user.getpassword());
    boolean ret = this.staffservice.verifyloginuser(user);
    if(ret == true) {
      return new responseentity<>("登陆成功", httpstatus.ok);
    }
    return new responseentity<>("登陆失败", httpstatus.non_authoritative_information);
  }
 
}

最后,贴一下启动类的代码
