我使用的是JDK 1.8.0_05, dubbo-admin版本是2.5.4-SNAPSHOT，也遇到了一样的问题。解决方案如：

1、webx的依赖改为3.1.6版；

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

2、添加velocity的依赖，我用了1.7；

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

3、对依赖项dubbo添加exclusion，避免引入旧spring

 <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>

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

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

确定war包解压后lib目录没有spring 3 以下的依赖就行。然后运行正常了。

5、dubbo-admin一定要布暑在TOMCAT 的ROOT下，直接把原ROOT下的系统自带文件删除，把dubbo-admin所有文件COPY进去，不能用dubbo-admin文件夹了。 否则进去无法查询，会报错。
