dubbo-admin在jdk1.8下报错问题（已解决）

在虚拟机上部署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

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/alibaba/dubbo.git

下载导入源码后，修改如下配置：

1、webx的依赖改为3.1.6版

    com.alibaba.citrus
    citrus-webx-all
    3.1.6

2、添加velocity的依赖，我用了1.7

    org.apache.velocity
    velocity
    1.7

3、对依赖项dubbo添加exclusion，避免引入旧spring

    com.alibaba
    dubbo
    ${project.parent.version}
    
        
            org.springframework
            spring

4、webx已有spring 3以上的依赖，因此注释掉dubbo-admin里面的spring依赖

逐个项目编译，重新打包，部署。

成功！
