- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我在 REST 后端项目中使用以下组件:

我可能在以下问题上绊倒了,RequestMappingHandlerMapping 的“没有找到用于自动连接的匹配 bean”:http://forum.spring.io/forum/spring-projects/web/112154-unable-to-autowire-requestmappinghandlermapping-in-controller
与此同时,我已经切换到基于 Java 的配置来替换我的 XML。这也解决了 Autowiring 问题。特此我的解决方案供其他人引用,其中包括更改 apiResourcePrefix 并使用 swagger.properties 外部配置文件。
