### Ⅲ. Describe what you expected to happen

startup success

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

1. create a feignClient
2. two or more dubbo service inject this feignClient
3. add seata-all pom
4. startup

### Ⅴ. Anything else we need to know?

### Ⅵ. Environment:

- JDK version : 1.8
- Dubbo version : 2.7.1
- Seata version：0.7.1
- OS : windows

Start with the stack-trace entry points in io.seata.spring.annotation.GlobalTransactionScanner.wrapIfNecessary, io.seata.spring.util.TCCBeanParserUtils, and io.seata.rm.tcc.remoting.parser.DefaultRemotingParser.parserRemotingServiceInfo. Reproduce the startup with one Feign client injected into two or more Dubbo services using the listed JDK, Dubbo, and Seata versions. Done means the application starts successfully without this NullPointerException.
