基于Maven项目管理的解决办法：

1. 
2. 
3. 

pom.xml里面：

1. <dependency>
2. <groupId>com.alibaba</groupId>
3. <artifactId>dubbo</artifactId>
4. <version>2.5.3</version>
5. <exclusions>
6. <exclusion>
7. <artifactId>spring</artifactId>
8. <groupId>org.springframework</groupId>
9. </exclusion>
10. </exclusions>
11. </dependency>
