生活加油:摘一句子:
“我希望自己能写这样的诗。我希望自己也是一颗星星。如果我会发光，就不必害怕黑暗。如果我自己是那么美好，那么一切恐惧就可以烟消云散。于是我开始存下了一点希望—如果我能做到，那么我就战胜了寂寞的命运。”

嗯,刚学的时候,一大堆,明白是配置了啥,不知道为啥那么配,嗯,今天把配置思想和小伙伴分享,是很简单的那种,不足之处请留言.
SpringSecurity的配置基于WebSecurityConfigurerAdapter的实现类,我们这里主要讲基本配置,即configure(HttpSecurity http)方法的配置,其实大都有默认值,我们可以直接用默认值,也可以自己设置.
私以为简单配置三点:
认证(SpringSecurity在第一次登录做认证,这时候只进行认证,不进行授权(鉴权处理))
表单认证:涉及到的配置包括前端登录请求的url,登录失败,登录成功返回的页面url,已及表单返回字段的用户名密码K的设置,还有登陆成功回调处理和登录失败回调处理.这里要注意登录数据是通过key/value的形式来传递.
自定义认证,(验证码):自定义验证采用,在自定义过滤器的方式,在最开始插入一个过滤器链,需要自定义异常,自定义失败登录失败处理器,注意这里的失败处理器要和表单登录使用同一个失败处理器.
授权(基于RBAC权限控制):
授权这样分析基于RBAC的权限控制,即用户分配角色,角色分配权限.需要配置根据访问路径得到需要的角色的处理类(FilterlnvocationSecurityrMetadataSource),根据返回角色进行鉴权处理类(AccessDecisionManager) , 同时判断是否登录,还需要配置认证失败的处理器.
注销登录
注销登录默认的url为"/logout".需要配置,注销登录处理器

下面就上面讲的代码分析
一．认证:
１．configure(HttpSecurity http)方法的配置:
