【問題概述】

    最近在學習dubbo，用dubbo-admin原始碼打成的war包，安裝dubbo管理平臺，部署到本機的tomcat遇到了問題，提示如下：

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

【環境概述】

    · windows8 作業系統

    · Java version “1.8.0_73”

    · dubbo-admin 2.5.3

    · apache-tomcat-7.0.57

【解決方案】

    修改dubbo-admin的pom依賴，重新打一個war包，部署。

        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>

        2、新增velocity的依賴，版本為1.7；

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

        3、對依賴項dubbo新增exclusion，避免引入舊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spring3以上的依賴，因此註釋掉dubbo-admin裡面的spring依賴

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

【總結】

    通過對原始碼做以上修改後，從Eclipse中重新生成的war包，便解決了不相容的問題。資源連結地址：dubbo-admin war包檔案，可在jdk1.8環境下直接部署到tomcat。
