用typescript写sapui5应用的一些坑

坑1：Component.ts漏写@namespace注解，导致异常

/** * @namespace ui5.walkthrough */

会导致编译成的js，缺少组件命名空间，声明实现 IAsyncContentCreation 接口也不会被正确识别

应用会抛异常

Failed to load component for container container - Error: Interface 'sap.ui.core.IAsyncContentCreation' must be implemented for component 'sap.ui.core' when 'createContent' is implemented asynchronously
Error: Interface 'sap.ui.core.IAsyncContentCreation' must be implemented for component 'sap.ui.core' when 'createContent' is implemented asynchronously

补上注解后

/** * @namespace ui5.walkthrough */

编译的js文件，组件正确的带上了命名空间UIComponent.extend("ui5.walkthrough.Component"

应用也正常运行了

总结：以前我以为注释都是给人看的，一般都懒得写，实际有些注解会影响下ui5 cli工具的编译结果，间接也就影响了程序。需要谨慎对待所有@相关的注解
