严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
java.lang.IllegalArgumentException: class [com.tiancom.pas.common.config.ContextInitializer] must implement ApplicationContextInitializerclass com.tiancom.pas.common.config.ContextInitializer is not assignable to interface org.springframework.context.ApplicationContextInitializer
求指点下

Answer 1

看错误提示
class [com.tiancom.pas.common.config.ContextInitializer] must implement ApplicationContextInitializer
你的类com.tiancom.pas.common.config.ContextInitializer要实现这个接口ApplicationContextInitializer
