Jetty practices-embedded running Jetty

Jetty is most commonly used to embed jetty into its own Java application.ProgramAt this time, Jetty runs as a servlet container in the background and accepts users' HTTP requests. The following is the simplest method to embed jetty.

1. First create a Java project using Maven

MVN archetype: generate-dgroupid = com. Google. Code. garbagecan. jettystudy-dartifactid = jettystudy-darchetypeartifactid = Maven-Archetype-Quickstart-dinteractivemode = false2. Modify the POM file and add or modify the compilation and dependency sections.

<Project xmlns = "http://maven.apache.org/POM/4.0.0" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" <br/> xsi: schemalocation = "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <br/> <modelversion> 4.0.0 </modelversion> <br/> <groupid> COM. google. code. garbagecan. jettystudy </groupid> <br/> <artifactid> jettystudy </artifactid> <br/> <packaging> jar </packaging> <br/> <version> 1.0-Snapshot </version> <br/> <Name> jettystudy </Name> <br/> <URL> http://maven.apache.org </URL> <br/> <build> <br/> <plugins> <br/> <plugin> <br/> <artifactid> Maven-compiler-plugin </artifactid> <br/> <inherited> true </inherited> <br/> <configuration> <br/> <source> 1.6 </source> <br/> <target> 1.6 </Target> <br/> <debug> true </debug> <br/> </configuration> <br/> </plugin> <br/> </plugins> <br/> </build> <br/> <dependencies> <br /> <dependency> <br/> <groupid> Org. eclipse. jetty. aggregate </groupid> <br/> <artifactid> jetty-all </artifactid> <br/> <version> 8.0.4.v20111024 </version> <br/> <type> jar </type> <br/> <scope> provided </scope> <br/> </dependency> <br/> <groupid> JUnit </ groupid> <br/> <artifactid> JUnit </artifactid> <br/> <version> 3.8.1 </version> <br/> <scope> test </scope> <br /> </dependency> <br/> </dependencies> <br/> </Project>3. Create a server class, start jetty server, and use hellohandler to process the requests sent by the browser;

Package COM. google. code. garbagecan. jettystudy. sample1; </P> <p> Import Org. eclipse. jetty. server. server; </P> <p> public class myserver {<br/> Public static void main (string [] ARGs) throws exception {<br/> server Server = new server (8080); <br/> server. sethandler (New hellohandler (); </P> <p> server. start (); <br/> server. join (); <br/>}< br/>}4. Create a handler class and process all client requests

Package COM. google. code. garbagecan. jettystudy. sample1; </P> <p> Import Java. io. ioexception; </P> <p> Import javax. servlet. servletexception; <br/> Import javax. servlet. HTTP. httpservletrequest; <br/> Import javax. servlet. HTTP. httpservletresponse; </P> <p> Import Org. eclipse. jetty. server. request; <br/> Import Org. eclipse. jetty. server. handler. abstracthandler; </P> <p> public class hellohandler extends acthandler {<br/> Public void handle (string target, request baserequest, httpservletrequest request, httpservletresponse response) <br/> throws ioexception, servletexception {<br/> response. setcontenttype ("text/html; charset = UTF-8"); <br/> response. setstatus (httpservletresponse. SC _ OK); <br/> baserequest. sethandled (true); <br/> response. getwriter (). println ("<p> Hello World </p>"); <br/> response. getwriter (). println ("request URL:" + target); <br/>}< br/>}5. Run the myserver class and access http: // localhost: 8080/in a browser. You can see "Hello World !" And the requested URL.
