概述
企業(yè)內(nèi)部一般都有一套單點登錄系統(tǒng)（常用的實現(xiàn)有apereo cas），所有的內(nèi)部系統(tǒng)的登錄認證都對接它。本文介紹spring boot的程序如何對接CAS服務。
常用的安全框架有spring security和apache shiro。shiro的配置和使用相對簡單，本文使用shrio對接CAS服務。

spring boot配置
application.properties

shiro.cas=https://cas.xxx.com # 這是CAS服務的地址shiro.server=http://127.0.0.1:8080 # 自己應用的地址，測試使用127即可 |
應用配置
初始化shiro bean，將文件放到任意子包下即可，比如xxx.config，spring boot會自動掃描加載

程序中獲取登錄的用戶名
上述配置完成后，就可以找程序中獲取登錄用戶的名字了

public String getUsername() { Subject subject = SecurityUtils.getSubject(); if (subject == null || subject.getPrincipals() == null) { return DEFAULTUSER; } return (String) subject.getPrincipals().getPrimaryPrincipal(); } |
總結
shiro使用還是比較簡單的，使用的時候只需要修改application.properties即可
以上就是本文的全部內(nèi)容，希望對大家的學習有所幫助，也希望大家多多支持服務器之家。
