Question

我刚刚从Spring Security 3升级到4，控制器中的@AuthenticationPrincipal注释输入参数现在为空。我设法使用已弃用的org.springframework.security.web.bind.annotation.AuthenticationPrincipal解决了这个问题，但是当使用org.springframework.security.core.annotation包中的那个时，它是空的。

如果我这样做，它也会起作用：
User activeUser = (User) ((Authentication) principal).getPrincipal();

我尽可能地遵循迁移指南。

这是我的spring-security.xml：

我只是想通了。它确实是Spring Security deprecated @AuthenticationPrincipal的副本。不幸的是，从来没有找到那个帖子。

我改变了

<mvc:annotation-driven>
    <mvc:argument-resolvers>
        <bean class="org.springframework.security.web.bind.support.AuthenticationPrincipalArgumentResolver" />
    </mvc:argument-resolvers>
</mvc:annotation-driven>

要

<mvc:annotation-driven>
    <mvc:argument-resolvers>
        <bean class="org.springframework.security.web.method.annotation.AuthenticationPrincipalArgumentResolver" />
    </mvc:argument-resolvers>
</mvc:annotation-driven>

在我的applicationContext.xml中。

Spring Security 4 @AuthenticationPrincipal为空，包含core.annotation.AuthenticationPrincipal但不是web.bind.annotation.AuthenticationPrincipal
