Tomcat Valve什么是 Valve 和 Pipeline Tomcat中容器的pipeline机制 - coldridgeValley - 博客园 没错，V 社中的 V 就是 Valve 的缩写（阀），因此 steam （蒸汽）这个意思就很明确了 XD 在 Tomcat 中，Pipeline和 Valve是其处理请求的重要概念。 Pipeline 是一系列 Valve 的有序集合。它类似于一个处理请求的流水线，每个 Valve 都代表一个处理步骤。 Valve 是 Pipeline 中的处理单元，负责执行特定的任务，例如身份验证、访问控制、日志记录、请求过滤等。 而 Tomcat 由 Connector 和 Container组成，请求由 Connector 包装为 Request 后交 Container 处理，第一层是 Engine 容器。Engine 不直接调用 Host 处理请求，而是通过 Pipeline 组件。Container 有 4 种：Engine、Host、Context、Wrapper，相互包含。4 种容器都有 Pipeline 组件，每个 P ...
