Dubbo 管理控制台启动报错

参考：
安装Dubbo管理控制台
2.5.4-SNAPSHOT dubbo admin error
下载dubbo-admin-2.5.4.war

初次使用dubbo管理控制台，启动tomcat后，访问url报错，查看tomcat启动日志，发现以下错误：

ERROR context.ContextLoader - Context initialization failed

查看github相关的issue，有两种解决办法：

1. 更换jdk8

dubbo-admin-2.5.4不支持jdk8，最高支持到jdk1.7

此方法最为方便。

2. 升级用到的spring包

原先的war包中lib包的内容：

更改后的内容：

3.1.4的包可以自行下载，或者在本地repository中拷贝。

3. 小技巧

其他相关的搭建管理台的教程都说到一点，删除tomcat目录下webapps目录下ROOT目录中的全部内容，把此war包解压出来的内容全部拷贝至空的ROOT目录中去。因为管理台界面中有点按钮是按照 / 的方式访问，不那样做的话对页面友好有一定影响。
