### 相关issue https://github.com/alibaba/spring-cloud-alibaba/issues/1909 ### 背景 背景见我之前提的PR：https://github.com/alibaba/spring-cloud-alibaba/pull/1915 目前该PR已被我关闭，因为我发现从feign.Client的继承体系来看，seata的实现是不合理的，所以，有了这个新的PR。 ### feign.Client的继承体系  从继承体系上来看，feign.Client主要包含两大类： - LoadBalancerFeignClient，用于处理负载均衡策略的Client - 其他Client，用于增强的Client，即充当delegate的Client，比如上图中的TracingFeignClient、SeataFeignClient等 ### seata的定位 seata在feign.Client的继承体系中的定位是增强，具体点讲，就是在发送请求之前把事务ID带上，没有其它作用了，更不用说负载均衡的作用了。 所以，seata不应该继承LoadBalancerFeignClient，生成SeataLoadBalancerFeignClient类，而只应该保留SeataFeignClient，把SeataFeignClient加入到delegate链中就可以了。 这样就遗留了一个问题，如何才能把SeataFeignClient加入到delegate链中呢？ 让我们看看`SeataFeignObjectWrapper.wrap()`方法，在这里，只要动态修改LoadBalancerFeignClient的delegate属性，把SeataFeignClient加进去就可以了，参考sleuth中的`TraceFeignObjectWrapper.wrap()`方法，我们使用反射来动态修改delegate。 ### 为什么删除SeataFeignContext和SeataContextBeanPostProcessor 我们看下SeataFeignContext的两个getInstance()方法： ```java public class SeataFeignContext extends FeignContext...
