当将login.xhtml设置为我的主页时，它不起作用 [英] When set login.xhtml as my homepage it does not work
问题描述
当我将我的login.xhtml页面设置为web.xml作为欢迎文件时，它不起作用，我的意思是它显示的页面很好，但是当我按登录时没有任何反应，但是当我手动进入时到登录页面http://localhost:8080/fileuploadWithPreview/login.xhtml的情况下，它运行完美，有什么主意吗?
when i set my login.xhtml page to be the web.xml to be the welcome file, it does not work, i mean it displays the page just fine but when i press log in nothing happens, but when i manually go to the log in page http://localhost:8080/fileuploadWithPreview/login.xhtml it works perfectly, any ideas why this is ?
web.xml:
<?xml version="1.0" encoding="UTF-8"?>

好了，这样就可以了，正当我按下登录按钮时，它带我回到登录页面，但是它已经对用户进行了身份验证，如何在登录按钮上获取它，才能一次进入index.html页面已验证?
Ok so it is working, just when i press the login button it takes me back to the login page but it has already authenticated the user, how do i get it on the login button to go to the index.html page once authenticated ?
登录页面:
<div id="site_content">
<div id="content">
<h:body>
<form method="post" action="j_security_check">
<p>You need to log in to access protected information.</p>
<table>
<tr>
<td>User name:</td>
<td><input type="text" name="j_username" /></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="j_password" /></td>
</tr>
</table>
<p><input type="submit" value="Login" />
<!--<h:commandButton value="This will reset all the data " type="button" > </h:commandButton> -->
<input type="reset" name="Login-reset" value="Reset" onclick="alert('This will reset all the data');" />
</p>
</form>
</h:body>
</div>
</div>
推荐答案
用<url-pattern>*.xhtml</url-pattern>替换<url-pattern>/faces/*</url-pattern>，并删除所有URL中的所有/faces/路径.这样，一切都应该按预期工作.
Replace <url-pattern>/faces/*</url-pattern> by <url-pattern>*.xhtml</url-pattern> and get rid of all /faces/ paths in all your URLs. This way everything should work as expected.
说明:<welcome-file>期望当前请求的文件夹(！)中的物理存在文件，该文件本应为index.xhtml或login.xhtml，而<form-login-page>期望完整的URI应为/faces/login.xhtml.当您将文件夹映射用于JSF时，这并不太好.因此，只需将其映射到*.xhtml上，您就不必担心虚拟URL.
Explanation: the <welcome-file> expects a physically existing file in the currently requested folder(!) which should have been index.xhtml or login.xhtml and the <form-login-page> expects a fullworthy URI which should have been /faces/login.xhtml. That don't mix quite well when you use a folder mapping for JSF. So just map it on *.xhtml and you never need to worry about virtual URLs.
