HmilyTcc，服务实现端一直报错

[grape-pzz]

服务实现端一直报如下错误：
com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Expected ':' at line 1 column 49 path $.participantId

找到原因了：
1、服务消费端会在拦截器中将事务信息存到request的header中，如下
public class HmilyFeignInterceptor implements RequestInterceptor {

@Override
public void apply(final RequestTemplate requestTemplate) {
    RpcMediator.getInstance().transmit(requestTemplate::header, HmilyContextHolder.get());
}

}
2、高版本的RestTemplate.headers会将事务（json字符串）信息截取，导致服务接收端解析json格式失败
{"transId":-5821096666862862336,"participantId":-5821096650890952704,"action":1,"role":1,"transType":"TCC"}
截取成{"transId":-5821096666862862336,"participantId}
存到header的“_HMILY_TRANSACTION_CONTEXT”中

考虑降低springcloud的版本或者重写这个拦截器
