使用Spring进行精确的RequestMapping [英] Exact RequestMapping with Spring

问题描述

我在春季有以下内容

@RequestMapping("/hello")

但是，Spring会自动为/hello/和/hello.*添加映射.如何完全匹配网址?

However Spring automatically adds mappings for /hello/ as well as /hello.*. How do I do an exact URL match?

仅/hello应该有效，其他应为404

Only /hello should work, anything else should 404

推荐答案

关闭RequestMappingHandlerMapping上的后缀匹配(useSuffixPatternMatch)将解决您的问题，但是，如果使用<mvc:annotation-driven/>，实际上并不是那么容易在您的配置中(而不是手动布线所有必需的基础结构bean).在这种情况下，定义其他类型为RequestMappingHandlerMapping的bean不会产生任何作用.

Turning off suffix matching (useSuffixPatternMatch) on RequestMappingHandlerMapping will solve your problem, but doing so is actually not so easy, if you use <mvc:annotation-driven/> in your configuration (instead of manually wiring all the necessary infrastructure beans). In this case defining an additional bean of type RequestMappingHandlerMapping won't have any effect.

您有两个选择:

1. 删除<mvc:annotation-driven/>，将其扩展为等效的bean定义集，您可以在其中应用useSuffixPatternMatch设置.

1. Remove <mvc:annotation-driven/> expanding it to an equivalent set of bean definitions where you can apply the useSuffixPatternMatch setting.

保持现状<mvc:annotation-driven/>，并使用此处描述的更简单的解决方法: https://jira.springsource.org/browse/SPR-9371 .基本上，这会添加一个BeanPostProcessor来检索由mvc命名空间创建的RequestMappingHandlerMapping bean，并设置上述标记.

Keep <mvc:annotation-driven/> as it is, and use a much easier workaround described here: https://jira.springsource.org/browse/SPR-9371. This basically adds a BeanPostProcessor which retrieves the RequestMappingHandlerMapping bean created by the mvc namespace, and sets the above mentioned flag.

还有另一张票据，它要求自定义RequestMappingHandlerMapping是由mvc命名空间创建的，而没有像上面那样应用hack.您可以考虑对此票进行投票.

There is also another ticket requesting that it should be much easier to customize the RequestMappingHandlerMapping created by the mvc namespace without applying hacks like above. You can consider voting on this ticket.
