Spring安全性无法初始化上下文

时间：2014-07-23 23:43:40

标签： java spring spring-mvc spring-security thymeleaf

我正在阅读官方的春季文档示例：

在没有它的情况下向应用程序添加spring安全性：http://docs.spring.io/spring-security/site/docs/3.2.x/guides/helloworld.html

创建自定义登录 http://docs.spring.io/spring-security/site/docs/3.2.x/guides/form.html

并成功为我的应用添加了安全性。但是，当我去添加自定义登录时，文档会讨论依赖关系“因为我们的项目将messages-jc项目添加为依赖项......”所以我将其添加到我的pom中。由于我添加了它，它会抛出一个错误，如下所示。

如果我排除我的SecurityWebApplicationInitializer然后运行应用程序，我可以删除此错误，但是系统没有正确地重定向到登录页面，并且登录页面无法正常工作（我使用th：if和none if if语句工作就像所有if语句都是真的一样，即使我说：if =“false”）。如果我删除了jc-messages依赖项，那么它会正确重定向，但登录页面仍然无法正常工作并尝试登录会引发invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN错误。

似乎安全类被多次注册时会触发错误，但是当我拿走SecurityWebApplicationInitializer时，没有任何东西正在注册该类。我觉得有一些基本的东西我缺少，因为我遵循一个简单的教程，但我无法弄清楚它是什么。除了是一个春天的问题，我唯一能想到的另一件事就是Thymeleaf出了问题，这使得登录页面无法正常工作。

感谢任何帮助！

SecurityWebApplicationInitializer.java 

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

    public SecurityWebApplicationInitializer() {
        super(SecurityConfig.class);
    }
}

pom.xml 注释掉其他依赖项以隔离springframework依赖性问题

在Spring Security中使用基于Java的配置时，CSRF protection is enabled by default。您可以将其关闭为http.csrf().disable()。
