grails - Grails URL映射优先规则

Question

使用Grails进行以下URL映射

'/api/abcdef' (resources: 'abcDef')
'/api/abc' (resources: 'abc')

调用/api/abcdef会使用AbcController.index()而不是format的def参数调用AbcDefController。但是，将/api/abcdef/1调用正确解析为AbcDefController.show()。看起来像grails url-mapping-report会报告的错误

|   GET    | /api/abcdef                                      | Action: index    |

在AbcDefController下。

但是，如果将两个URL的顺序更改为

'/api/abc' (resources: 'abc')
'/api/abcdef' (resources: 'abcDef')

Grails可以将/api/abcdef正确解析为AbcDefController.index()。

但无论哪种情况，/api/abc123都将使用AbcController.index()的format参数解析为123
URL映射优先级的机制是什么？以上行为对吗？我使用Groovy 2.4.5和Grails 2.5.3。

Answer 1

[W]hen two mappings could apply to the same incoming URI, the one that wins is the one that has:

1. Fewer double wildcards (** or $var**), or if both are equal then
2. Fewer single wildcards (* or $var), or if both are equal then
3. More non-wildcard path segments, or if both are equal then
4. The furthest left wildcard (/foo//baz beats /foo/bar/), or if both have their leftmost wildcard in the same place then
5. The one with more constraints
