控制器在Spring MVC中的生命周期 [英] Controller's life-cycle in Spring MVC

Spring MVC中Controller的生命周期是什么？

What is the lifecycle of a Controller in Spring MVC?

何时创建控制器，何时销毁？它是在多个线程之间共享的吗？是否可以同时使用多个请求。

When is the controller created, when destroyed? Is it shared among multiple threads? Can it be in use simultaneously by more than one request.

是的，它们由线程/请求共享;你应该把它们写成线程安全的。他们应该是无国籍的。通常他们会引用一个完成所有工作的Spring服务。控制器处理Web层的绑定，验证和路由。

Yes, they're shared by threads/requests; you should write them to be thread-safe. They should be stateless. Usually they have a reference to a Spring service that does all the work. Controllers handle binding, validation, and routing for the web tier.
