我们如何使用Spring获取应用程序根目录的绝对路径？
我有一个可以在 http://serverA/m/ 或 http://serverA/mobile/。我有一个带有搜索表单的共享标头，需要转到 http://serverA/installationName /搜索。
但是，如果我使用
如果我使用
我尝试过
:url value="search"> 和 & lt c:url value="/search"> 给我“无法解析控制器 URL /search”，即使我有一个使用 @RequestMapping("/search") 定义的控制器
I have an app that may run at http://serverA/m/ or http://serverA/mobile/. I have a shared header with a search form that needs to go to http://serverA/installationName/search.
However, if I use <form action="/search"> it goes to the root of the server, not the tomcat application.
If I use <form action="search"> it goes to a path relative to the current page. (i.e http://serverA/m/someOtherPage/search
I've tried <c:url value="search"> and <c:url value="/search"> but neither of them seem to work.
In intelliJ, <c:url value="/search"> gives me "Cannot resolve controller URL /search" even though I have a controller defined with @RequestMapping("/search")

Using
<c:url>is the way. Ignore what the IDE tells you. They are not good at that. Just try to run it.博佐是对的。我也使用过 HTML BASE 标签：
如果您可以将此标签放在几个地方（最好仅在一个 JSP 中），您可以使代码更简洁。
Bozho is right. I have used HTML BASE tag too:
If you can put this tag in a few places (ideally in only one JSP) you can get your code cleaner.
您还可以（除了其他响应者提示之外）还使用 Spring JSP 标记 (spring:url)，该标记是在 JSTL c:url 标记之后建模的（请参阅 Bozhos 回复）。顶级域名参考：
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/spring.tld.html#spring.tld.url
以及这个mvc的底部:resources 块的示例使用：
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-static-resources
You can (apart from other responders hints) also use Spring JSP tag (spring:url) which is modeled after the JSTL c:url tag (see Bozhos reply). The tld reference:
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/spring.tld.html#spring.tld.url
And the bottom of this mvc:resources block for an example use:
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-static-resources
如果您的表单标记是 jsp 标记（可能是），您将无法直接在属性中嵌入 c:url 标记。
在这种情况下，我会执行以下操作：
you will not be able to imbed the c:url tag directly in the attribute, if your form tag is a jsp tag (perhaps, <sf:form>).
In that situation I do the following:
