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

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。

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
