Question

在我的春季安全应用程序中，我使用以下代码放置了我的注销按钮

<li><a href="<c:url value="j_spring_security_logout"/>">Log out</a></li>

现在，当我的网址为http://localhost:8080/servletname时，注销工作正常。

即使它是http://localhost:8080/servletname/abc，它也能正常工作。

但是当网址为http://localhost:8080/servletname/abc/xyz时，当我点击退出按钮时，我会在页面重定向到http://localhost:8080/servletname/abc/j_spring_security_logout时获得404页面。

我该如何解决这个问题？

Answer 1

“＆gt;退出link特别是部分：

Given a base URL and a relative URL (that does not begin with a slash), a full URL is derived as follows:

If the base URL ends with a slash the full URL is derived by appending the relative URL to the base URL. For example, if the base URL is http://nosite.com/dir1/dir2/ and the relative URL is gee.html, the derived URL is http://nosite.com/dir1/dir2/gee.html.
If the base URL doesn't end with a slash, the last piece of the base URL is considered a resource, so the full URL is derived by appending the relative URL to the parent of the base URL. For example, if the base URL is http://nosite.com/dir1/dir2 and the relative URL is gee.html, the derived URL is http://nosite.com/dir1/gee.html

你正在使用相对路径，在url：

的开头使用“/”使其成为绝对路径

<a href="<c:url value="/j_spring_security_logout"/>">Log out</a>

spring security：当具有较长的相对路径时，注销不起作用
