链接(href)与 Spring MVC 中的应用程序无关? [英] Links (href) not relative to application in Spring MVC?

问题描述

我正在将一个在端口 8080 上使用简单 java HTTPServer 的项目更改为使用 Spring MVC servlet 框架的项目.

I am in the process of changing a project which used a simple java HTTPServer on port 8080 to that which uses the Spring MVC servlet framework.

应用程序中有很多链接，如下所示:

There are lots of links in the application like so:

<a href=\"/rule\">Manage rules</a><br/>

使用以下请求效果很好:

Which worked fine using requests such as:

http://localhost:8080/send

但是，除非我像这样将 servlet 名称放在前面，否则这些现在不起作用:

However, these now don't work unless I put the servlet name in front like so:

"<a href=\"/ServletName/rule\">Manage rules</a><br/>"

只是想知道有什么办法可以解决这个问题，还是只需更改所有 href 链接以在它们前面添加 servlet 名称即可?

Just wondering is there any way around this, or is it a matter of just changing all the href links to add the servlet name in front of them?

请注意，我不必在方法开始时在 @RequestMapping 调用中添加 servlet 名称，只有它的链接有问题.例如.无需在前面添加 servlet 名称即可正常工作

Note that I dont have to add the servlet name in my @RequestMapping calls at the start of methods, its only links that are the problem. E.g. this works fine without adding the servlet name in front

@RequestMapping(value = "/send", method = RequestMethod.GET)

推荐答案

如果您在视图层中使用 JSP，请使用具有链接标记的标记库(或自己编写).基本上，链接标签必须通过做

If you use JSPs in your view layer, use a tag library that has a link tag (or write one yourself). Basically, the link tag has to create the url by doing

HttpServletResponse.encodeURL(originalUrl)

标签JSTL 会这样做，但它只生成 URL，而不生成链接标记，但它可以像这样让您到达那里:

The <c:url> tag in JSTL does that, but it only generates the URL, not the link tag, but it can get you there like this:

<c:url value="your/relative/url" var="somevar" />
<a href="${somevar}">Link Text</a>
