我有
ERR_TOO_MANY_REDIRECTS
重定向到 logout.jsp 页面时出现异常。我想我给出这个异常是因为错误的 spring security 配置文件，但我不知道它在哪里。如果有人知道如何解决它，请告诉我。 这是什么意思？我的代码:
Spring 安全配置:
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests()
.antMatchers("/**").access("IS_AUTHENTICATED_ANONYMOUSLY")
.antMatchers("/**").access("hasRole('ROLE_USER')")
.antMatchers("/login").permitAll()
.antMatchers("/register").permitAll()
.antMatchers("/logout").permitAll()
.antMatchers("/js/**", "/css/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.loginProcessingUrl("/j_spring_security_check")
.failureForwardUrl("/login?error=true")
.permitAll()
.and()
.logout()
.logoutUrl("/logout")
.logoutSuccessUrl("/logout")
.permitAll();
}
}
注销按钮:

<div class="container">
<a class="navbar-brand">Contacts List</a>
<div class="collapse navbar-collapse">

谢谢大家。
最佳答案
通过请求 /logout，您可以处理注销，成功注销后，您可以重定向到 /logout，它会尝试另一次注销。
The URL that triggers log out to occur (default is "/logout"). If CSRF protection is enabled (default), then the request must also be a POST. This means that by default POST "/logout" is required to trigger a log out. If CSRF protection is disabled, then any HTTP method is allowed.
和LogoutConfigurer#logoutSuccessUrl
The URL to redirect to after logout has occurred.
您必须使用两个不同的 URL 进行处理并成功注销。第一个 URL 不能存在，并且仅适用于 LogoutFilter 。第二个必须由您的应用程序实现。
