Could not resolve placeholder 'tencent-config.sdk-app-id' in value "${tencent-config.sdk-app-id}"

springboot项目启动失败org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'TIMConfig': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'tencent-config.sdk-app-id' in value "${tencent-config.sdk-app-id}"

application.properties（或 application.yml）文件中未找到tencent-config.sdk-app-id 这个配置，你加上就好了。
