This is why there is context varibles in Talend, you can develop your job using context variables to avoid hard coded values then load context from external file or prompt user to enter these values and you can also define multiple contexts, please see talend help.
这就是Talend中存在上下文变量的原因,您可以使用上下文变量来开发您的工作以避免硬编码值然后从外部文件加载上下文或提示用户输入这些值,您还可以定义多个上下文,请参阅talend帮助。
