我的Web应用程序存在此问题,我通过Tomcat执行基于表单的身份验证,并将其重定向到徽标图像文件,而不是重定向到包含该徽标图像的index.html文件...
我要去:
http://localhost:8080/GenTreeUploader/Servlet
然后它给我登录表单并且在成功登录后,我不在那个URL中,但是我被重定向到:
http://localhost:8080/GenTreeUploader/images/gdia_logo.png
我去的时候经过身份验证:
http://localhost:8080/GenTreeUploader/Servlet
然后我被重定向到正确的位置,而不是图像文件。
我正在附加我的web.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

好?任何想法为什么它不能按预期工作?提前谢谢。
答案 0 :(得分:5)
重定向实际上正在发生,因为登录文件中请求的那些资源实际上受到保护,因为我选择了整个路径作为安全资源:
<web-resource-collection>
<web-resource-name>Wildcard means whole app requires authentication</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
所以我创建了一个名为“Admin”的新文件夹,并移动了需要在那里保护的文件,并修改了servlet的路径。这是我当前(固定)web.xml的样子:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<!-- WELCOME FILE LIST -->
<welcome-file-list>
<welcome-file>Admin/Servlet</welcome-file>
</welcome-file-list>
<!-- Security -->
<security-constraint>
<web-resource-collection>
<web-resource-name>Wildcard means whole app requires authentication</web-resource-name>
<url-pattern>/Admin/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
<user-data-constraint>
<!-- transport-guarantee can be CONFIDENTIAL, INTEGRAL, or NONE -->
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.html</form-error-page>
</form-login-config>
</login-config>
<!-- Main Servlet -->
<servlet>
<servlet-name>GenTreeUploaderServlet</servlet-name>
<servlet-class>org.ktu.gdia.presentation.web.GenTreeUploader</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>GenTreeUploaderServlet</servlet-name>
<url-pattern>/Admin/Servlet</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
60
</session-timeout>
</session-config>
</web-app>
所以现在Tomcat登录后不会将我重定向到图像或css文件,因为现在没有身份验证的任何人都可以访问它们。
