用于解析URI的Spring实用程序 [英] Spring utility for parsing URIs

问题描述

我想使用现有的Spring功能从URL中提取路径变量和查询参数。我有一个路径格式字符串，它对MVC @RequestMapping 或 UriComponentsBuilder 有效。我也有一条实际的道路。我想从该路径中提取路径变量。

I would like to extract path variables and query parameters from a URL using existing Spring features. I have a path format string which is valid for an MVC @RequestMapping or UriComponentsBuilder. I also have an actual path. I would like to extract path variables from that path.

例如。

String format = "location/{state}/{city}";
String actualUrl = "location/washington/seattle";
TheThingImLookingFor parser = new TheThingImLookingFor(format);
Map<String, String> variables = parser.extractPathVariables(actualUrl);
assertThat(variables.get("state", is("washington"));
assertThat(variables.get("city", is("seattle"));

它类似于 UriComponentsBuilder 的反转，这是我读到的Javadocs没有任何解析功能。

It is something like the inverse of UriComponentsBuilder, which from my reading of the Javadocs does not have any parsing features.

推荐答案

这就是：

    String format = "location/{state}/{city}";
    String actualUrl = "location/washington/seattle";
    AntPathMatcher pathMatcher = new AntPathMatcher();
    Map<String, String> variables = pathMatcher.extractUriTemplateVariables(format, actualUrl);
    assertThat(variables.get("state"), is("washington"));
    assertThat(variables.get("city"), is("seattle"));
