启动异常信息如下：

经查，发现为spring引用存在冲突导致的，项目主要引用spring 3.2.4.RELEASE版本，但是dubbo间接引入了spring-2.5.6.SEC03，导致冲突。

解决方法，将dubbo引入的spring屏蔽掉。

<dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.5.3</version><!-- <exclusions>          <exclusion>              <groupId>*</groupId>              <artifactId>*</artifactId>          </exclusion>      </exclusions> -->  </dependency>
