processing, the purpose is to encapsulate data. 8.Servlet is how the request is handled usually when we send a request like Http://localhost:8080/TomcatTest/login, How does the container find the Loginservlet class to handle it? In fact, Tomcat has a mapper class that is designed to hold the child container information in the container container in Tomcat, Before the Org.apache.catalina.connector.Request class goes into the container container, Mapper will be based on this request hostname, C

simple Web application that can run independently. Running the Java class directly will start an inline Tomcat server running on port 8080. Visit "http://localhost:8080" to see "www.yoodb.com" on the page. You can launch a standalone Web app with just 2 files. There is no need to install Tomcat-like application servers, or to package them into war files. You can start the app on the command line with "MVN Spring-boot:run". The "Org.springframework.bo

As you can see from the boot in the Springboot project name, Springboot's role is to create and launch a new spring-based framework project. It is designed to help developers easily create spring-based frameworks for standalone runs and product-level applications. Springboot will choose the most appropriate spring sub-

The Spring framework can be said to be one of the most popular application development frameworks used by Java developers. It is currently comprised of a large number of modules providing a range of services. Includes module containers, aspect-oriented programming (AOP) for building crosscutting concerns, security framework, data access

1, what is Spring boot. With the popularity of dynamic languages (Ruby, Groovy, Scala, node.js), Java development is particularly cumbersome: a wide range of configurations, inefficient, complex deployment processes, and third-party technology integration are difficult. To address the above issues, Spring Boot is launched by the new group. It uses the idea of "Convention over configuration" to get your pr
