Spring请求映射通配符异常 [英] Spring request mapping wildcard exceptions

问题描述

我可以将/**通配符放在请求映射的中间，例如:"/some/resource/**/somthing"

Can I put /** wildcard in a middle of request mapping such as: "/some/resource/**/somthing"

我可以在春季3做到这一点

In Spring 3 I can do this

@RequestMapping("/some/resource/**")

要映射

/some/resource/A  -> ControllerMethod1
/some/resource/A/B -> ControllerMethod1
/some/resource/A/B/C/D/E/F -> ControllerMethod1

用于任意数量的路径部分

for any number of paths parts

但是此映射过于贪婪，不允许我将子URL @RequestMapping("/some/resource/**/somthing")映射到另一个控制器，例如

However this mapping is too greedy and will not allow me to map a sub URL @RequestMapping("/some/resource/**/somthing") to another controller such as

/some/resource/A/somthing  -> ControllerMethod2
/some/resource/A/B/somthing -> ControllerMethod2
/some/resource/A/B/C/D/E/F/somthing -> ControllerMethod2

我该怎么做?

推荐答案

我认为无法按需要在URL映射中使用该ant样式，因为它将停止在下一个路径分隔符'/".

I thinks it's not possible to use that ant style in url mapping as you require, because it will stop on the next path separator character '/'.

我建议您尝试

I would suggest you to try 16.3.2.2. URI Template Patterns with Regular Expressions in order to map just the last part of the request (haven't tried this approach yet).

您还可以使用 PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE 匹配其余的请求，并在其中应用一些表达式. 查看此信息.

Also you can match the rest of the request using PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE, and apply some expression there. Check this post.

否则，您应该使用请求参数来匹配该条件 16.3.2.6.请求参数和标题值.

Otherwise you should use request parameters to match that condition 16.3.2.6. Request Parameters and Header Values.

您可以通过"myParam"，！myParam"或​​"myParam = myValue"之类的请求参数条件来缩小请求匹配范围.前两次测试是否存在请求参数，第三次测试特定参数值.这是一个带有请求参数值条件的示例.

You can narrow request matching through request parameter conditions such as "myParam", "!myParam", or "myParam=myValue". The first two test for request parameter presense/absence and the third for a specific parameter value. Here is an example with a request parameter value condition.

在这种情况下，您将使用params映射类似的内容

In this case you will map something like that using params

@RequestMapping(value = {"/some/resource/**"},  params="somthing")

或在方法签名中使用带有非必需属性的注释请求参数:

or use the annotation request parameter with not required attribute in method signature:

public void test(@RequestParam(value = "somthing", required=false) String str) {
