网址不明确，其中一个带有PathVariable [英] Ambiguous URLs, one with PathVariable

问题描述

我有Spring 3.2 Web应用程序，并且我的控制器具有以下请求映射:

I have Spring 3.2 web app and i have controller with following request mappings:

@RequestMapping(value = "/test/{param1}", method = RequestMethod.GET)
public String method1(@PathVariable(value = "param1") String param1, ..

@RequestMapping(value = "/test/login", method = RequestMethod.GET)
public String method2(//..

我可以确定是否有人请求url/test/login来调用method2?是否有哪个因素决定弹簧的处理方式?是否始终选择不带PathVariable的URL(如果存在)?我在Spring文档中找不到任何内容.

Can I be sure that if someone ask for url /test/login the method2 will be invoked? Are there any factors based on which spring decides how to handle it? Does it always choose URL without PathVariable if any exists? I can't find anything in Spring doc.

推荐答案

我可以确定如果有人要求输入/test/login网址，那么method2将被调用吗? 是的.

Can i be sure that if someone ask for url /test/login the method2 will be invoked? Yes.

根据具体情况解析映射，相关文档可在

The mappings are resolved by specificity, the relevant piece of doc is available here

具有较少URI变量和通配符的模式是 考虑得更具体.例如/hotels/{hotel}/*具有1个URI 变量和1个通配符，并且被认为比 /hotels/{hotel}/**作为1个URI变量和2个通配符.

A pattern with a lower count of URI variables and wild cards is considered more specific. For example /hotels/{hotel}/* has 1 URI variable and 1 wild card and is considered more specific than /hotels/{hotel}/** which as 1 URI variable and 2 wild cards.

如果两个模式具有相同的计数，则更长的模式是 考虑得更具体.例如，/foo/bar*更长， 被认为比/foo/*更具体.

If two patterns have the same count, the one that is longer is considered more specific. For example /foo/bar* is longer and considered more specific than /foo/*.

当两个样式的计数和长度相同时， 较少的通配符被认为更具体.例如 /hotels/{hotel}比/hotels/*更具体.

When two patterns have the same count and length, the pattern with fewer wild cards is considered more specific. For example /hotels/{hotel} is more specific than /hotels/*.

如果两个映射与请求匹配，则将应用更具体的内容.在这两个映射中，/test/login更具体.

If the two mappings match a request, a more specific will apply. Out of the two mappings, /test/login is more specific.
