Hooks.onEachOperator介绍

[英]Add or replace a named Publisher operator interceptor for each operator created ( Flux or Mono). The passed function is applied to the original operator Publisher and can return a different Publisher, on the condition that it generically maintains the same data type as the original. Use of the Flux/ Mono APIs is discouraged as it will recursively call this hook, leading to StackOverflowError.

Note that sub-hooks are cumulative. Invoking this method twice with the same key will replace the old sub-hook with that name, but keep the execution order (eg. A-h1, B-h2, A-h3 will keep A-B execution order, leading to hooks h3 then h2 being executed). Removing a particular key using #resetOnEachOperator(String) then adding it back will result in the execution order changing (the later sub-hook being executed last). Can be fully reset via #resetOnEachOperator().

This pointcut function cannot make use of Flux, Mono or ParallelFlux APIs as it would lead to a recursive call to the hook: the operator calls would effectively invoke onEachOperator from onEachOperator.
[中]为创建的每个操作符（Flux或Mono）添加或替换命名的发布者操作符拦截器。传递的函数应用于原始运算符发布服务器，并且可以返回不同的发布服务器，条件是它通常保持与原始服务器相同的数据类型。不鼓励使用Flux/MonoAPI，因为它会递归调用此钩子，从而导致StackOverflowerError。
请注意，子挂钩是累积的。使用同一个键调用此方法两次将用该名称替换旧的子钩子，但保留执行顺序（例如，A-h1、B-h2、A-h3将保留A-B执行顺序，导致钩子h3然后执行h2）。使用#resetOnEachOperator（String）删除一个特定的键，然后将其添加回去，将导致执行顺序发生变化（最后执行的是后面的子钩子）。可通过#resetOnEachOperator（）完全重置。
这个切入点函数不能使用Flux、Mono或ParallelFlux API，因为它会导致对钩子的递归调用：操作符调用将有效地从onEachOperator调用onEachOperator。
