Spring Security-即使凭据正确，身份验证也不起作用

本文介绍了Spring Security-即使凭据正确，身份验证也不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在我的应用程序中使用spring security，在那里我拦截了一些用于身份验证的URL.尽管URL "/securedMapping1" 提示用户通过显示登录页面来登录，但是该登录不起作用.即使我提供了正确的凭据，我也会通过调用URL进行身份验证失败即 authentication-failure-url ="/login?error不论正确/不正确的凭据，每次都会调用= true" .谁能帮助我找出问题所在?以下是重要文件中的代码:

I am using spring security in my application where I am intercepting some URLs for authentication. Although URL "/securedMapping1" is prompting for user to login by displaying login page, the login, however, is not working. Even if I give the correct credentials, I am going back to login page with "Bad credentials" error by invoking URL for failed authentication i.e, authentication-failure-url="/login?error=true" is called every time regardless of correct/incorrect credentials. Could anyone help me figure out whats going wrong? Below is the code from important files:

推荐答案

请参见 Spring Security参考:

-用户名参数包含用户名的请求参数的名称.默认为用户名".

- username-parameter The name of the request parameter which contains the username. Defaults to "username".
