Java 身份验证成功处理程序ref与登录处理url不兼容？

spring-security.xml：

<form-login        
        login-page="/admin/login"
        login-processing-url="/admin/postlogin"
        authentication-failure-url="/admin/login?error=true"
        default-target-url="/admin/dashboard"
        username-parameter="username" 
        password-parameter="password"
        authentication-success-handler-ref="customAuthenticationSuccessHandler"/>

没有

authentication success handler ref

它工作正常，我被重定向到仪表板，但是有了

authentication success handler ref

我在链接

/admin/postlogin

上看到一个空白页面。我需要在我的会话中使用这些属性，就像这样，它应该只调用一次。有什么想法吗？

您需要从自定义处理程序的onAuthenticationSuccess（）方法重定向到正确的URL

private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();

@Override
public void onAuthenticationSuccess(HttpServletRequest request, 
  HttpServletResponse response, Authentication authentication) throws IOException {
    //Your custom stuff
    handle(request, response, authentication);
}

protected void handle(HttpServletRequest request, 
    HttpServletResponse response, Authentication authentication) throws IOException {
    String targetUrl = "";//Place your target url detection logic here. 

    redirectStrategy.sendRedirect(request, response, targetUrl);
}

我不能做任何重定向，因为实现了AuthenticationSuccessHandler它只支持void函数我要求做重定向，而不是返回。在您实现自己的成功处理程序时，您有责任确定下一个url（如果成功的话）。将添加一些eamples。

private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();

@Override
public void onAuthenticationSuccess(HttpServletRequest request, 
  HttpServletResponse response, Authentication authentication) throws IOException {
    //Your custom stuff
    handle(request, response, authentication);
}

protected void handle(HttpServletRequest request, 
    HttpServletResponse response, Authentication authentication) throws IOException {
    String targetUrl = "";//Place your target url detection logic here. 

    redirectStrategy.sendRedirect(request, response, targetUrl);
}
