Java Embedded Web Server (with source code)

Many Java developers use Tomcat as the main server. Tomcat undoubtedly has many advantages. Tomcat is also the latest jdk api with the best support and relatively high stability. However, Tomcat's weakness is also obvious. After all, Tomcat is not a pure Java Server. to interact with tomcat, Java must use the physical path or related interfaces. Tomcat is very troublesome to use.

I believe many people have also used the ser-U FTP server, which is a well-established but very stable server and is very enterprising. In later versions of this server, their console was upgraded from the original CS mode to the BS mode, which can be said to be a revolutionary evolution. The BS mode console is easier to upgrade and optimize than the CS mode. They can use BS as the console, but do not deploy related application servers, that is, they have embedded Java servers.

In this article, the application-type Java Server mainly uses the Java main method to start an embedded application server platform and listen to a port, to continuously provide application services to local users or local area network users. What services you deploy depends on what applications you deploy. ,

Call class

Package COM. shine. framework. httpserver; </P> <p> public class example {<br/> Public static void main (string ARGs []) {<br/> httpservermanager manager = new httpservermanager (); <br/> // manager. initjettyhttpserverbywar ("/managesystemflex", <br/> // "C: // users // 123 // desktop // managesystemflex. war "," 8080 "); </P> <p> manager. initjettyhttpserver ("/managesystemflex", <br/> "E: // workspace // managesystemflex // webcontent", "8080 "); <br/>}< br/>

 

Initjettyhttpserverbywar is a Web application that calls a war package.Program;

The initjettyhttpserver method calls a webcontent web application;
