tcc BusinessActionContext get null

[ShootMooN]

Try to write a springboot dubbo tcc demo base on the dubbo-tcc-sample. When I run my code, the parameter 'BusinessActionContext actionContext' of method 'prepare' shows null. Have tried everything I can, but still can not solve this problem.

I have meet the same problem! dubbo2.7.3 + seata0.8.1+springBoot2.1.9, no solution found yet. someone said use the spring and XML to inject the Dubbo bean will works.

Hi Please check my correction: first->import io.seata.core.context.RootContext; final String xid = RootContext.getXID(); in each u wanna use the xid like this one, pls use my style: logger.info(String.format("======>prepareMinus account[%s] amount[%f], dtx transaction id: %s.", accountNo, amount, xid));

And...how about the businessActionContext? Seems...the sample writer only use the null value, I also correctted the sample as following codes and for your reference:

public boolean transfer(long from, long to, double amount) throws DemoRpcRunTimeException { BusinessActionContext businessActionContext = new BusinessActionContext(); Map<String, Object> actionContext = new HashMap(); actionContext.put("accountNo", from); actionContext.put("amount", amount); businessActionContext.setActionContext(actionContext);

一样的问题，而且这个seata-sample的demo好Low啊，都是xml的配置，很不利于学习，而且demo中的BusinessActionContext都是null，我想知道提交的作者脑子里在想什么？而且这个玩意官方就没有demo吗？

我也是这个问题，但是当我加上适用于SpringCloud+Feign模式下的TCC的注解@LocalTCC 的时候，就可以获取，而且那个demo中是使用的dubbo，并没有使用这个为SpringCloud+Feign模式，也没有加上这个注解，也许是版本的问题？
