Question

为什么不通过以下配置提示登录？当我尝试访问 / public / user 时，我收到错误403（访问被拒绝）。但是，如果我在WebServiceSecurityConfiguration.configure取消注释这些注释行，我会根据需要重定向到登录页面。为什么要正确配置登录时需要这些行，因为antMatcher首先匹配不同的路径。我想有一些冲突，错误配置AuthenticationEntryPoint，但我真的不知道这是怎么回事。我想要实现的是配置两个安全链，一个用于登录路径以获取JWT令牌，另一个用于Web服务以针对令牌进行身份验证。一切都与那些没有注释的线条完美配合，但我偶然注意到形式 - 登录在没有它们的情况下停止工作，并且我很困惑为什么会这样。

在声明添加

后，登录功能再次起作用

http.antMatcher("/secured/**")

作为WebServiceSecurityConfiguration.configure中的第一个电话。这是否意味着如果没有它，配置会否定表单登录，在此特定配置之后配置？此外，似乎antMatcher的位置可以是任意的，是这种情况吗？有人可以解释那里发生的事情吗？

Spring Security java配置混淆
