重命名包名 case3 为 case4
重命名 Case3Application.java 为 Case4Application.java
在 config(HttpSecurity http) 方法中对 formLogin 选项进行配置。需要包含以下设置:
创建 SuccessHandler 实现 AuthenticationSuccessHandler 接口,并实现 onAuthenticationSuccess 方法,自定义返回内容;
创建 FailureHandler 实现 AuthenticationFailureHandler 接口,并实现 onAuthenticationFailure 方法,自定义返回内容;
在 formLogin 配置项上增加 successHandler 和 failureHandler 配置
相关代码如下:
