Spring 4.2 will support case-insensitive path matching.您可以按以下方式配置它：
zzoitvuj2#
根据this webpost，您需要在Spring MVC中添加HandlerMapping和HandlerAdapter。Mapping将请求Map到相应的控制器，适配器负责使用控制器执行请求。
因此，您需要覆盖Map器和适配器的PathMatcher。
Ex（将使所有@Controllers不区分大小写）：
新匹配器：
applicationContext.xml:
添加了大约相同的，这< mvc:annotation-driven >将做。（感谢大卫公园的链接）

在Spring 3.2+ / Sping Boot 中，您现在可以使用简化的Java配置设置不区分大小写的URL匹配。
首先，你需要创建CaseInsensivePathMatcher.groovy或Java类：
接下来，为了实现这一点，你应该有一个用Springs @Configuration注解的类，它扩展了WebMvcConfigurerAdapter类，如下所示（注意，我的代码包含在.groovy classes中，因此在示例中不需要'return'关键字）：
然后将以下两个方法添加到类中：
就是这样，你现在应该是所有设置不区分大小写的URL的最低配置

Spring从5.3版开始默认不再使用PathMatcher，而是使用PathPatternMatcher。要配置PathPatternMatcher，请执行以下操作：

问题通过smat上报解决方案
在solution by smat中，有一个小的副作用（我会责怪spring-mvc）。
起初，
AntPathMatcher.doMatch()似乎根据requested-url和controller-method的请求Map字符串返回true/false（这是这里唯一应该做的事情）。但是，该方法还用于另一个目的（没有写在documentation！中）。另一个目的是在controller-method中收集@PathVariable的相应值。这些值在Map<String, String> uriTemplateVariables中收集并且这些收集的值被用于作为参数值传递给控制器方法。例如，我们有这样的控制器方法，
如果我们使用URL访问
/code/AbD，那么通过smatAntPathMatcher.doMatch()的解决方案，将收集Map<String, String> uriTemplateVariables中的@PathVariable值作为userCode->abd。由于我们使用小写的路径字符串，因此收集的值也是小写的。并且此小写的userCode值被传递给我们的控制器。但是，我很感谢smat的解决方案，到目前为止，它对我很好，没有任何其他问题。
解决方案
通过smat解决了这个问题。在扩展的
AntPathMatcher类中没有小写路径或模式字符串，我强迫我的扩展AntPathMatcher使用我的自定义AntPathStringMatcher。我的自定义AntPathStringMatcher在不改变实际字符串大小写的情况下进行大小写无关的匹配。在下面的解决方案代码中，大部分代码都是从原始类代码中复制的（由于私有访问，我想定制的代码被隐藏在子类中）。
自定义AntPathMatcher，

好吧，我不能回答你的问题（我试过了，我以为我能弄明白）。但是鉴于你在2天内没有收到任何回复，这里至少有一些线索：
这个例子似乎表明这是可能的：
http://webcache.googleusercontent.com/search?q=cache:ELj-ZQ8G4z0J:www.springbyexample.org/examples/sdms-simple-spring-mvc-web-module.html+case+insensitive+requestmapping+spring&cd=3&hl=en&ct=clnk&client=firefox-a
它在Spring中引用这个类
http://static.springsource.org/spring/docs/3.0.4.RELEASE/javadoc-api/org/springframework/web/servlet/mvc/support/ControllerClassNameHandlerMapping.html
我的猜测（也只是猜测）是，您需要扩展
<mvc:annotation-driven/>并使用正确的参数实现各个bean，以使其不区分大小写。请参阅：http://rapid-web.tumblr.com/post/296916668/what-does-annotation-driven-do
最后一点，我在阅读中注意到它说所有路径默认为小写，你验证过
/MyPath不是由@RequestMapping("/mypath")处理的吗？再一次，我尽我所能，只是想一想。也许它会让你走得足够沿着，问一个更具体的问题，引导你找到答案-这就是这些事情有时是如何工作的。祝你好运！
