部署dubbo-admin的时候报错
ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘uriBrokerService‘: Cannot create inner bean ‘(inner bean)‘ of type [com.alibaba.citrus.service.uribroker.impl.URIBrokerServiceImpl$URIBrokerInfo] while setting bean property ‘brokers‘ with key [0]; nested excepti on is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘(inner bean)#25‘: Cannot create inner bean ‘server‘ of type [com.alibaba.citrus.service.uribroker.uri.GenericURIBroker] while setting constructor argument; nested exception is org.springframework.beans.fact ory.BeanCreationException: Error creating bean with name ‘server‘: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property ‘URIType‘ of bean class [com.alibaba.citrus.service.uribroker.uri.GenericURIBroker]: Bean property ‘URIType‘ is not writable or has an invalid setter method.

查看源码如下：
set方法不很标准，导致高版本jdk（jre）不能支持，导致报错。
解决方法：
1、更换服务器jdk版本。
2、修改dubbo-admin tomcat默认jdk版本。
3、修改dubbo-admin项目依赖（dependency）从新打包。
主要说下第三种方法：
https://github.com/apache/dubbo/releases/tag/dubbo-2.5.4
下载完解压后：在目录dubbo-dubbo-2.5.4\dubbo-admin打开pom.xml文件
1、修改webx的依赖改为3.1.6版（版本号在dubbo-dubbo-2.5.4\pom.xml中名字叫 <webx_version>3.1.6</webx_version>）
2、添加velocity的依赖，我用了1.7
3、对依赖项dubbo添加exclusion，避免引入旧spring
4、打包部署后发现报错缺失applicationContext.xml文件这是因为spring默认版本太高导致在dubbo-dubbo-2.5.4\pom.xml中修改spring_version版本为3.2.9
5、打war包部署完成。
解决dubbo-2.5.4在contos 系统jdk1.8环境下部署报错的问题
