Spring security中怎么自定義成功和失敗

本篇文章為大家展示了Spring security中怎么自定義成功和失敗，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。

實(shí)現(xiàn)步驟

1. 復(fù)制上一示例的源碼

重命名包名 case3 為 case4

重命名 Case3Application.java 為 Case4Application.java

2. 在 WebSecurityConfig 中配置登錄頁(yè)

在 config(HttpSecurity http) 方法中對(duì) formLogin 選項(xiàng)進(jìn)行配置。需要包含以下設(shè)置:

• 創(chuàng)建 SuccessHandler 實(shí)現(xiàn) AuthenticationSuccessHandler 接口，并實(shí)現(xiàn) onAuthenticationSuccess 方法，自定義返回內(nèi)容；

• 創(chuàng)建 FailureHandler 實(shí)現(xiàn) AuthenticationFailureHandler 接口，并實(shí)現(xiàn) onAuthenticationFailure 方法，自定義返回內(nèi)容；

• 在 formLogin 配置項(xiàng)上增加 successHandler 和 failureHandler 配置
