问题描述
我在 REST API 中使用文件名(例如:GET http://xxx/api/myImage.jpg)问题是@PathVariable 删除了.jpg".这个问题已经在这里问过几次并回答了.但对我不起作用.

所以我搜索然后在
https://jira.springsource.org/browse/SPR-6524
"... 根本不应该与手动 DefaultAnnotationHandlerMapping 实例结合使用；这目前被设计为一个非此即彼的选择，与 和 非常相似."
"... is simply not supposed to be combined with manual DefaultAnnotationHandlerMapping instances; this is designed as an either-or choice at present, quite similar to and ."
mvc 命名空间是进行简化的配置".
"mvc namespace are make simplifed configurations".
真正的问题是mvc是做什么的?并改变了?
Real question is mvc what does do? and changed?
我发现我自己这些东西..
I found my self these things..
- 拦截器配置已更改.(bean 配置中需要 mvc namspace)
- useDefaultSuffixPattern 不起作用.
- 添加了 JSON 消息转换器.如果杰克逊图书馆可用
- @PathVariable 参数会自动添加到模型中
还有其他的吗?
提前致谢！
推荐答案
mvc:annotationDriven 标签实质上设置了您的 Spring 上下文，以允许将请求分派到控制器.
The mvc:annotationDriven tag essentially sets you your Spring context to allow for dispatching requests to Controllers.
该标签将配置两个 bean DefaultAnnotationHandlerMapping 和 AnnotationMethodHandlerAdapter.
The tag will configure two beans DefaultAnnotationHandlerMapping and AnnotationMethodHandlerAdapter.
您可以从 spring 文档中找到更多信息:
