我正在使用来自here的BalusC指南，以了解如何使用Apache Shiro。我在Windows 7 x64中使用JSF 2.2，Neatbeans 7.4，Shiro 1.2.2，JavaEE 7，Glassfish 4。我的问题是，当我通过Netbeans尝试视图选项或者当我尝试使用其URL直接访问页面时，我的login.xhtml页面上的组件不会呈现，但是当我运行项目并自动加载它时它会起作用（它是我的欢迎页面）。普通文本正常显示。
login.xhtml页面：
<?xml version='1.0' encoding='UTF-8' ?>

Login.java bean：

try {
SecurityUtils.getSubject().login(new UsernamePasswordToken(username, password, remember));
SavedRequest savedRequest = WebUtils.getAndClearSavedRequest(Faces.getRequest());
Faces.redirect(savedRequest != null ? savedRequest.getRequestUrl() : HOME_URL);
}
catch (AuthenticationException e) {
Messages.addGlobalError("Unknown user, please try again");
e.printStackTrace(); // TODO: logger.
}
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public boolean isRemember() {
return remember;
}
public void setRemember(boolean remember) {
this.remember = remember;
}
}
我也收到此错误
A managed bean with a public field (“HOME_URL”) should not declares any scope other than @Dependent
即使它似乎有用......

我有两个网页：
/login.xhtml
/app/index.xhtml
有什么建议吗？ （我是一个菜鸟所以请温柔！：P）
答案 0 :(得分：1)
今天我遇到了同样的问题。 BalusC在不同主题中找到答案（或至少是一个提示）。
在我的案例中，页面与FacesServlet的url-pattern不匹配。我所要做的就是在web.xml中更改模式：
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

签出此日志行
SEVERE: Unable to load annotated class: model.LoginBean, reason: java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
Shiro依赖于slf4j进行日志记录，并且您缺少slf4j依赖项。您可以在此处下载这些罐子：http://www.slf4j.org/download.html
我建议你将以下jar添加到你的类路径中：
如果要使用其他形式的日志记录（log4j，commons日志记录，java日志记录，logback），则需要使用以下方法之一替换简单jar：
有关slf4j的更多详细信息，请查看手册：http://www.slf4j.org/manual.html
答案 2 :(得分：-1)
public static final String HOME_URL =＆＃34; app / index.xhtml＆＃34;;
错误的地方，我想你现在应该知道你应该更喜欢私人公开声明变量。所以请改用它。 干杯
private static final String HOME_URL =＆＃34; app / index.xhtml＆＃34 ;;
