使用servlet来让jvm在独立的java线程中来处理每个请求是Servlet容器的一个关键的优势。每个servlet是一个具有特殊组件的java类来对应http请求。Servlet容器的主要功能是将请求转发给正确的Servlet处理,然后再把处理的结果交给web服务器。在大多数情况下,Servlet容器运行在一个jvm实例中,但是当Servlet容器需要多个jvm实例时,...
第二步,web服务器将请求转发给Servlet容器; 第三步,如果对应的Servlet还没有被加载,那么该Servlet将会被动态加载进Servlet容器的地址空间; 第四步,Servlet容器触发Servlet的init()方法,该方法只会在加载的时候触发一次; 第五步,Servlet容器触发Servlet的service()方法来处理http请求,从请求中读取数据并且生成响应。这个...
Using servlets allows the JVM to handle each request within a separate Java thread, and this is one of the key advantage of Servlet container. Each servlet is a Java class with special elements responding to HTTP requests. The main function of Servlet contain is to forward requests to correct...

A custom tag is a user-defined JSP language element. When a JSP page containing a custom tag is translated into a servlet, the tag is converted to operations on a tag handler. The web container then invokes those operations when the JSP page’s servlet is executed....
Let’s first understand how filters work. AFiltercan be called either before or after servlet execution. When a request is dispatched to a servlet, theRequestDispatchermay forward it to another servlet. There’s a possibility that the other servlet also has the same filter. In such scenarios,...
@component annotation to create a spring bean. this step is important because it allows us to register the filter in the servlet container. there is another way to register filters, which offers more control and customization and it can be achieved by utilizing the filterregistrationbean class. ...
