Yang-xingchen opened a new issue, #7186:
URL: https://github.com/apache/incubator-seata/issues/7186
### Ⅰ. Issue Description
在使用TCC模式下时，调用到commit方法和rollback方法时，方法内BusinessActionContext.getBranchType()得到内容为null。
### Ⅱ. Describe what happened
If there is an exception, please attach the exception trace:
```
```
### Ⅲ. Describe what you expected to happen
### Ⅳ. How to reproduce it (as minimally and precisely as possible)
1. 接口使用@LocalTCC注解
2. prepare方法使用@TwoPhaseBusinessAction注解,
3. prepare方法、commit方法、rollback方法第一个参数均为BusinessActionContext
4. prepare方法可以正常获取到branchType为TCC，commit方法和rollback方法获取branchType为null
Minimal yet complete reproducer code (or URL to code):
### Ⅴ. Anything else we need to know?
目前调试发现在org.apache.seata.rm.tcc.TCCResourceManager中branchCommit方法和branchRollback方法参数中有branchType值且取值正常，但方法体中未使用该值(包括创建BusinessActionContext对象)。
当前代码仓库中也未使用该值[TCCResourceManager](https://github.com/apache/incubator-seata/blob/2.x/tcc/src/main/java/org/apache/seata/rm/tcc/TCCResourceManager.java)
