we will look at two ways to register a Java Servlet in Jakarta EE — one using aweb.xmlfile, and the other using annotations. Then we’ll register servlets in Spring Boot using XML configuration, Java configura
Servlets have access to the entire family of Java APIs, including theJDBC APIto access enterprise databases. Servlets can also access a library of HTTP-specific calls and receive all the benefits of the mature Java language, including portability, performance, reusability, and crash protection. ...

Servlet就基于这种想法产生了,利用Java运行时可动态加载来处理新的请求,只需要启动一次服务器进程,只加载一次JVM,之后这个JVM再动态加载另外的类。其执行效率比传统CGI快得多了。Servlet的优点如下: 1、只需要启动一个系统进程以及加载一个JVM,大大降低系统开销。
