Content: There are some security issues in the previous article because we need to transform request and response into ServletRequest and Servletresponse, A servlet programmer who understands how this servlet container works can transform ServletRequest and servletresponse down and then invoke the parse () of request and response. and Sendstaticresource (). So we need to use the appearance class to solve, add two Requestfacade and Responsefacade, then

Publish the Spring-boot project in the same way as a normal Web project under the Tomcat container First, modify the packaging form Set in Pom.xml Second, remove the embedded Tomcat plugin Find the spring-boot-starter-web dependency node in Pom.xml and add the following code in it Third, add the dependency of Servlet-api

Running in the Jetty container requires opening provided because the jetty container already has its own implementation of SERVLET,JSTL and JSP. However, when the project needs to be deployed into Tomcat, because the Tomcat container is not implemented with SERVLET,JSTL and

Org.apache.catalina.connector.Request has a recycle method. As the name implies recycling, the context of this request is cleared, of course, there is no session. When this new request comes in, it is not created, it can be used directly to bind the stateless object to a new context, which is equivalent to the function of an object pool.So the reason is that the main thread executes very quickly, when the main thread binding request is cleaned up and no longer associated with the session. Our n

This section adds different control processes for static and dynamic resource access based on the previous section. In this example, the path "/servlet/" is specially processed.I. Mainly starting from the main method in httpserver1, the request and response objects are parsed first. If the request path contains the/servlet/path, the request enters servletprocesser1 for processing, otherwise, it enters staticprocessor for processing. In servletprocessor1, the request and response are encapsulated

I've always wondered how Tomcat actually did it, and when I first learned it, I didn't know what the difference was between the container and the server, the difference betweenApache and Tomcat and the difference between Web servers, containers, and application servers . Direct look at the source words will feel confused, itself did not have in-depth understandin

Deep into the Tomcat source analysis session is what! What a session is. As we all know, the HTTP protocol itself is stateless (stateless), which is sufficient and unaffected for some simple page displays. And for the increasingly complex dynamic pages, applications, all kinds of need to login authentication scenes, it is powerless. Think of a logged in user is still a prompt login, what will be the feeling. Therefore, most applications that need to

Function: Automatically assembles the configuration information for spring applicationcontext.xml when the Web container is started. Because it implements the Servletcontextlistener interface, when the Web. XML configures this listener, when the container is started, it executes the method it implements by default. Contextloader is associated with this class in Contextloaderlistener, so the entire load conf

Objective Today, I studied the problem of Url-pattern in the Web.xml configuration file on Tomcat. This problem actually bothered me before I graduated and was busy looking for a job. After finding a job, there is no time to worry about the problem. After all, I was lazy and didn't take the time to study. Today, I saw some of Tomcat's source code to understand this url-pattern mechanism. Let me come here at one by one. The general structure of

When it comes to spring and SPRINGMVC, there are a lot of people who have been working for years and can't tell you what the difference is, if you ask him what MVC technology he uses, he'll say we use spring and mybatis, or spring and hibernate.In the subconscious mind will think that SPRINGMVC is spring, and I think so, haha.Although the SPRINGMVC and spring have a certain connection, but they also have the difference. I'll briefly describe the followingFirst of all, SPRINGMVC and spring are bo

ContainerA container is a collection of objects of a specific type, a container's type is divided into sequential containers, container adapters, and associative containers, a sequential container aggregates a single type element into a container, and then stores and accesses these elements based on location.The order

Reprinted from http://blog.csdn.net/iAm333For Servlets, servlet containers, and a servlet container-tomcat These concepts are very clear, reproduced underBefore in open source China saw an article, "Beginner Java Web Development, please stay away from the various frameworks, from the Servlet development", feel very good. I felt ashamed to think of myself before having been obsessed with various frameworks.
