1 出现的问题：在eclipse使用jetty启动dubbo项目，出现
2019-08-06 10:35:27.568|ERROR|initServletBean|org.springframework.web.servlet.FrameworkServlet:498|Scanner-0|Context initialization failed:MSG|org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘${dubbo.application.name}’: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property ‘logger’ threw exception; nested exception is java.lang.IllegalStateException: Extension instance(name: slf4j, class: interface com.alibaba.dubbo.common.logger.LoggerAdapter) could not be instantiated: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;
2 解决的方法：这是因为jdk的版本问题，我的是1.7版本，所以不行，后来我把jdk的版本改成1.8后，项目就可以运行起来了
