如何使用spring security，相信百度过的都知道，总共有四种用法，从简到深为：
1、不用数据库，全部数据写在配置文件，这个也是官方文档里面的demo；
2、使用数据库，根据spring security默认实现代码设计数据库，也就是说数据库已经固定了，这种方法不灵活，而且那个数据库设计得很简陋，实用性差；
3、spring security和acegi不同，它不能修改默认filter了，但支持插入filter，所以根据这个，我们可以插入自己的filter来灵活使用；
4、暴力手段，修改源码，前面说的修改默认filter只是修改配置文件以替换filter而已，这种是直接改了里面的源码，但是这种不符合oo设计原则，而且不实际，不可用。
本文主要介绍了关于spring security自定义认证登录的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。
1.概要
1.1.简介
spring security是一种基于 spring aop 和 servlet 过滤器的安全框架，以此来管理权限认证等。
1.2.spring security 自定义认证流程
1）认证过程
生成未认证的authenticationtoken

|
↑（获取信息） （根据authenticationtoken分配provider） authenticationfilter -> authenticationmanager -> authenticationprovider ↓（认证） userdetails（一般查询数据库获取） ↓（通过） 生成认证成功的authenticationtoken ↓（存放） securitycontextholder |
2）将authenticationfilter加入到security过滤链（资源服务器中配置），如：
|
1
|
http.addfilterbefore(authenticationfilter, abstractpreauthenticatedprocessingfilter.class) |
或者：
|
1
|
http.addfilterafter(authenticationfilter, usernamepasswordauthenticationfilter.class) |
2.以手机号短信登录为例
2.1.开发环境
- springboot
- spring security
- redis

/** * 手机登录token * * @author ： catalpaflat */public class mobileloginauthenticationtoken extends abstractauthenticationtoken { private static final long serialversionuid = springsecuritycoreversion.serial_version_uid; private static final logger logger = loggerfactory.getlogger(mobileloginauthenticationtoken.class.getname()); private final object principal; public mobileloginauthenticationtoken(string mobile) { super(null); this.principal = mobile; this.setauthenticated(false); logger.info("mobileloginauthenticationtoken setauthenticated ->false loading ..."); } public mobileloginauthenticationtoken(object principal, collection<? extends grantedauthority> authorities) { super(authorities); this.principal = principal; // must use super, as we override super.setauthenticated(true); logger.info("mobileloginauthenticationtoken setauthenticated ->true loading ..."); } @override public void setauthenticated(boolean authenticated) { if (authenticated) { throw new illegalargumentexception( "cannot set this token to trusted - use constructor which takes a grantedauthority list instead"); } super.setauthenticated(false); } @override public object getcredentials() { return null; } @override public object getprincipal() { return this.principal; } @override public void erasecredentials() { super.erasecredentials(); }} |
注：
setauthenticated()：判断是否已认证
- 在过滤器时，会生成一个未认证的authenticationtoken，此时调用的是自定义token的setauthenticated()，此时设置为false -> 未认证
- 在提供者时，会生成一个已认证的authenticationtoken，此时调用的是父类的setauthenticated()，此时设置为true -> 已认证

注：attemptauthentication()方法：
- 过滤指定的url、httpmethod
- 获取所需请求参数数据封装生成一个未认证的authenticationtoken
- 传递给authenticationmanager认证

注：authenticate()方法
- 获取过滤器封装的token信息
- 调取userdetailsservice获取用户信息（数据库认证）->判断通过与否
- 通过则封装一个新的authenticationtoken，并返回

注：configure()方法
实例化authenticationfilter和authenticationprovider
将authenticationfilter和authenticationprovider添加到spring security中。
