在虛擬機器上部署dubbo-admin的時候報錯：

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

檢視原始碼如下：

解決方法：

1、更換伺服器jdk版本。

2、修改dubbo-admin tomcat預設jdk版本。

3、修改dubbo-admin專案依賴（dependency）從新打包。

主要說下第三種方法：

https://github.com/alibaba/dubbo.git

下載匯入原始碼後，修改如下配置：

1、webx的依賴改為3.1.6版

<dependency>
    <groupId>com.alibaba.citrus</groupId>
    <artifactId>citrus-webx-all</artifactId>
    <version>3.1.6</version>
</dependency>
 

<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity</artifactId>
    <version>1.7</version>
</dependency>

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>${project.parent.version}</version>
    <exclusions>
        <exclusion>
            <groupId>org.springframework</groupId>
            <artifactId>spring</artifactId>
        </exclusion>
    </exclusions>
</dependency>
 

<!--<dependency>-->
    <!--<groupId>org.springframework</groupId>-->
    <!--<artifactId>spring</artifactId>-->
<!--</dependency>-->

成功！
