春季安全性：相对路径较长时，注销不起作用

Question

在我的Spring Security应用程序中，我的注销按钮带有以下代码

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

现在，当我的URL为http://localhost:8080/servletname ，注销正常。

即使它是http://localhost:8080/servletname/abc它也可以正常工作。

但是，当URL为http://localhost:8080/servletname/abc/xyz时，单击注销按钮时，我得到一个404页面，因为该页面被重定向到http://localhost:8080/servletname/abc/j_spring_security_logout 。

我该如何解决？

Answer 1

“>退出查看链接，尤其是一部分：

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 

您正在使用相对路径，请在网址开头使用“ /”将其设为绝对路径：

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