博客介绍了Spring的async注解，其可使方法在单独线程执行，调用者无需等待。还对比了Spring WebFlux和MVC在并发模型、阻塞特性等方面的差异，指出WebFlux默认线程非阻塞。此外，提到使用艺电的async jar包让Java支持async - await。

spring 的 async 注解

@Async will make it execute in a separate thread i.e. the caller will not wait for the completion of the called method.

Both Spring MVC and Spring WebFlux support client-server architecture but there is a key difference in the concurrency model and the default behavior for blocking nature and threads. In Spring MVC, it is assumed that applications can block the current thread while in webflux, threads are non-blocking by default. It is the main difference between spring webflux vs mvc.

Reactive and non-blocking generally do not make applications run faster. The expected benefit of reactive and non-blocking is the ability to scale the application with a small, fixed number of threads and lesser memory requirements. It makes applications more resilient under load, because they scale in a more predictable manner.
