*  dubbo-spring-boot-starter，启动异常，报错如下：
    
     *  **Springboot版本**：2.1.6.RELEASE
     *  **dubbo-spring-boot-starter版本**：
        
            <dependency>
                    <groupId>com.alibaba.boot</groupId>
                    <artifactId>dubbo-spring-boot-starter</artifactId>
                    <version>0.1.2.RELEASE</version>
               </dependency>
 *  异常如下：

*  经排查，是springboot版本号与dubbo-spring-boot-starter**版本不匹配**导致的，
    
     *  如果您现在使用的Dubbo版本低于2.7.0，请使用如下对应版本的Dubbo Spring Boot
    
    <table> 
     <thead> 
      <tr> 
       <th><strong>Dubbo Spring Boot</strong></th> 
       <th><strong>Dubbo</strong></th> 
       <th><strong>Spring Boot</strong></th> 
      </tr> 
     </thead> 
     <tbody> 
      <tr> 
       <td>0.2.1.RELEASE</td> 
       <td>2.6.5+</td> 
       <td>2.x</td> 
      </tr> 
      <tr> 
       <td>0.1.2.RELEASE</td> 
       <td>2.6.5+</td> 
       <td>1.x</td> 
      </tr> 
     </tbody> 
    </table>

所以可以将上面代码中将dubbo-spring-boot改成0.2.1版本
