使用spring和dubbo报错：Error creating bean with name 'com.gsyshop.service.ItemService':_course

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： ``` 2019-09-21 01:43:41 [ERROR] -ContextLoader.java(353) -Context initialization failed

spring+ dubbo tomcat启动报错 Error creating bean with name_course

使用http://blog.csdn.net/aixiaoyang168/article/details/51362675#comments方式，启动报错，信息太长发到这里，请 帮忙看一下 org.s

http://192.168.25.128:8080/dubbo-admin/报404？_course

dubbo-admin-2.5.4.war也复制到tomcat/webapps下了，startup.sh也启动了，zookeeper在这之前也启动了。为什么访问http://192.168.25.128:8080/dubbo-admin/报404？
