今天在linux上部署dubbo-admin-2.5.4，一直報錯：

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

仔細(xì)對比了一下部署成功的環(huán)境，發(fā)現(xiàn)配置沒有什么不同。于是重新下載了一個部署包，也在自己的電腦上安裝了一次，還是報同樣的錯誤。

反編譯dubbo的代碼看了一下，發(fā)現(xiàn)getter和setter方法確實不是很符合規(guī)范：

折騰了半天，終于在網(wǎng)上找到遇到同樣問題的帖子，見https://github.com/alibaba/dubbo/issues/50

重新安裝了jdk 1.7后，問題解決。

dubbo-admin在jdk 1.8上部署出錯問題
