fegin threadlocal

在使用Feign调用时，如果开启了Hystrix，那么无法直接获取ThreadLocal中的数据。解决这个问题的方法有两种。一种是将hystrix的enabled设为false，即feign.hystrix.enabled=false，这样就可以继续使用ThreadLocal。另一种方法是将ThreadLocal换成InheritableThreadLocal，也就是使用InheritableThreadLocal来保存数据。InheritableThreadLocal是ThreadLocal的子类，可以解决父线程和子线程的数据传输问题。 这样，当开启了Hystrix时，依然可以在子线程中获取到父线程中设置的数据。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
