解决方案

好像是类冲突，有重复的类引起的。一个DubboNamespaceHandler.class文件存在于多jar中。

解决方案二：
Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.//这句话是说连接你本机的5432端口被拒绝然后让你检查主机名和端口是否正确。

解决方案三：
我的也报错，。。。求各位大神指导

解决方案四：
ERROR com.alibaba.dubbo.common.Version - #com.alibaba.dubbo.common.Version.checkDuplicate(Version.java:144)# - [DUBBO] Duplicate class com/alibaba/dubbo/config/spring/schema/DubboNamespaceHandler.class in 3 jar [file:/D:/guyatong/shopworkspace/jpa-demo/WebRoot/WEB-INF/lib/dubbo-2.8.4-shaded.jar!/com/alibaba/dubbo/config/spring/schema/DubboNamespaceHandler.class file:/D:/guyatong/shopworkspace/jpa-demo/WebRoot/WEB-INF/lib/original-dubbo-2.8.4.jar!/com/alibaba/dubbo/config/spring/schema/DubboNamespaceHandler.class file:/D:/guyatong/shopworkspace/jpa-demo/WebRoot/WEB-INF/lib/dubbo-2.8.4.jar!/com/alibaba/dubbo/config/spring/schema/DubboNamespaceHandler.class] dubbo version: 2.8.4 current host: 127.0.0.1

解决方案五：
从下网上看 [main] ERROR org.springframework.test.context.TestContextManager /applicationContext.xml文件
