1.spring版本和dubbo版本由maven管理,jdk12 tomcat9 dubbo部署在linux服务器上 可以跑起来。版本详细配置如图
2.启动服务层工程时报错信息如下:

9月 21, 2019 1:43:41 上午 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.BeanCreationException: Error creating bean with name 'com.gsyshop.service.ItemService': Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError
3.尝试方法:更换dubbo版本 2. 5 2.6 均不行
4.服务层和web层的dubbo配置如下;
服务层.xml
