Failed to parse configuration class ：未能解析配置类；有知道这个咋么解决的么？求解答！
现在做的是一个web项目，添加了applicationcontext.xml。错误如下：
org.apache.catalina.core.StandardContext listenerStart
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.kuaihai.haiban.configuration.AppConfig]; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.profiles.active' in value "classpath:application-${spring.profiles.active}.properties"
