I am using JDK 1.8.0_05, dubbo-admin version is 2.5.4-SNAPSHOT, and I have the same problem. Solutions such as:

1. The dependency of webx is changed to version 3.1.6;

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

2. Add the dependency of velocity, I used 1.7;

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

3. Add exclusion to the dependency dubbo to avoid introducing the old 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 already has spring 3 or higher dependency, so comment out the spring dependency in dubbo-admin

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

After decompressing the war package, make sure that the lib directory does not have any dependencies below spring 3. Then it runs normally.

5. Dubbo-admin must be placed under the ROOT of TOMCAT, directly delete the system’s own files under the original ROOT, and copy all the files of dubbo-admin into it. The dubbo-admin folder cannot be used. Otherwise, you cannot check if you enter, and an error will be reported.
