使用 David Heffelfinger 的书在 Java 中保护 Web 应用程序

Question

我正在尝试构建David Heffelfinger的书《使用NetBeans开发Java EE 5:使用这个流行的IDE快速轻松地开发专业企业Java EE 5应用程序》第2章中所描述的securewebapp。在执行最后一步(glassfish特定的安全配置)时，我试图运行该程序。我得到以下错误消息:

deploy?DEFAULT=/home/bjorn/NetBeansProjects/securewebapp/build/web&name=securewebapp&contextroot=/securewebapp&force=true failed on GlassFish Server 3+ 
 Error occurred during deployment: Exception while deploying the app [securewebapp] : org.xml.sax.SAXParseException; lineNumber: 28; columnNumber: 57; Deployment descriptor file WEB-INF/web.xml in archive [web].  cvc-pattern-valid: Value 'index.jsp' is not facet-valid with respect to pattern '/.*' for type '#AnonType_war-pathType'.. Please see server.log for more details.
/home/bjorn/NetBeansProjects/securewebapp/nbproject/build-impl.xml:1033: The module has not been deployed.
See the server log for details.
BUILD FAILED (total time: 2 seconds)

日志文件显示:

SEVERE: DPL8015: Invalid Deployment Descriptors in Deployment descriptor file WEB-INF/web.xml in archive [web]. 
Line 28 Column 57 -- cvc-pattern-valid: Value 'index.jsp' is not facet-valid with respect to pattern '/.*' for type '#AnonType_war-pathType'.

有人知道该怎么做才能获得安全的web应用程序工作吗?

Answer 1

更改<login-config>并将/放入文件路径

<form-login-config>
    <form-login-page>/index.jsp</form-login-page>
    <form-error-page>/errorpage.jsp</form-error-page>
</form-login-config>

编辑:如何基于JAAS形式的身份验证工作?

基于表单的身份验证的工作方式是，用户首先尝试从可公开访问的资源文件(如index.jsp或home.jsp)访问受保护的资源(如/admin/admin.jsp)，如果未经身份验证，则重定向到<form-login-page>(如login.jsp)。

此时容器已经保存了用户试图访问的受保护资源的URL，如果身份验证成功，会自动将重定向到该资源。如果身份验证失败，您已经知道用户将被重定向到<form-error-page>。

因此，我建议您将index.jsp重命名为login.jsp，并创建一个新的index.jsp，其中包含到/admin/admin.jsp的链接。您也可以尝试直接访问admin.jsp。然后它就会按照你想要的那样工作。
