spring boot + spring security +前后端分离【跨域】配置 + ajax的json传输数据
1.前言
网上各个社区的博客参差不齐 ，给初学者很大的困扰 ，
我琢磨了一天一夜，到各个社区找资料，然后不断测试，遇到各种坑，一言难尽啊，要么源码只有一部分，要么直接报错。。。
最后实在不行，直接去看过滤器的实现目的和原理
直到看到这个
final class FilterComparator implements Comparator<Filter>, Serializable { private static final int STEP = 100; private Map<String, Integer> filterToOrder = new HashMap<String, Integer>(); FilterComparator() { int order = 100; put(ChannelProcessingFilter.class, order); order += STEP; put(ConcurrentSessionFilter.class, order); order += STEP; put(WebAsyncManagerIntegrationFilter.class, order); order += STEP; put(SecurityContextPersistenceFilter.class, order); order += STEP; put(HeaderWriterFilter.class, order); order += STEP; put(CorsFilter.class, order); order += STEP; put(CsrfFilter.class, order); order += STEP; put(LogoutFilter.class, order); order += STEP; put(X509AuthenticationFilter.class, order); order += STEP; put(AbstractPreAuthenticatedProcessingFilter.class, order); order += STEP; filterToOrder.put("org.springframework.security.cas.web.CasAuthenticationFilter", order); order += STEP; put(UsernamePasswordAuthenticationFilter.class, order); order += STEP; put(ConcurrentSessionFilter.class, order); order += STEP; filterToOrder.put( "org.springframework.security.openid.OpenIDAuthenticationFilter", order); order += STEP; put(DefaultLoginPageGeneratingFilter.class, order); order += STEP; put(ConcurrentSessionFilter.class, order); order += STEP; put(DigestAuthenticationFilter.class, order); order += STEP; put(BasicAuthenticationFilter.class, order); order += STEP; put(RequestCacheAwareFilter.class, order); order += STEP; put(SecurityContextHolderAwareRequestFilter.class, order); order += STEP; put(JaasApiIntegrationFilter.class, order); order += STEP; put(RememberMeAuthenticationFilter.class, order); order += STEP; put(AnonymousAuthenticationFilter.class, order); order += STEP; put(SessionManagementFilter.class, order); order += STEP; put(ExceptionTranslationFilter.class, order); order += STEP; put(FilterSecurityInterceptor.class, order); order += STEP; put(SwitchUserFilter.class, order); }
我才搞清楚了过滤器链的具体顺序和流程

2.环境

这个接口内部是做用户密码校验的，原理是根据用户名从数据库获取信息，然后以相同的加密方式比较是否一样，
然后注册权限列表

数用枚举类 装数据 实现了接口

这些是自定义处理，用户返回前端json类型数据的

上图画出来的两句是前端关键，访问有spring security的后端必须有，否则会报错，当前如果没有security ，则可不写
4.数据库
5.测试
（1）进入前端页面 index.html
访问网址 http://localhost:8001/html/index.html
（2）点击获取认证信息，未登录被拒绝了
（2）输入账户 =cen
密码 = 11
点击登录 【想要自动登录则勾选复选框，登录后会多出个cookie】
（3）再次点击获取认证信息
输入框
（4）输入框写点东西再发送，
（5）点击登出
