Jersey is the Jax-rs (JSR311) Open source reference implementation for building RESTful WEB service. In addition , Jersey provides some additional APIs and extension mechanisms so developers can scale Jersey to their own needs

The theory of things here I will not say more! This example is the implementation of the rest of the three basic get, put, delete functions, data stored in the MONGO. Below is the directory structure of the entire project

The project entrance is main in App.java,

Run the results such as: After running the App class entrance, the program listens to 8080 ports, we will find that we do not need Tomcat and other web containers can easily create Web services, concise and fast.

The following figure is run out of the TestClient test client output results, additions and deletions to check the output

The following figure is a successful addition of data after running add data in MONGO.

I'll take the following. Listing code

One, MAVEN's pom.xml code is as follows:

<project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd" ><modelversion >4.0.0</modelversion><groupid>com.example</groupid><artifactid>jerseyuserdemo</ Artifactid><packaging>war</packaging><version>0.0.1-snapshot</version><name> Jerseyuserdemo Maven webapp</name><url>http://maven.apache.org</url><repositories>< Repository><id>snapshot-repository.java.net</id><name>java.net Snapshot repository for Maven </name><url>https://maven.java.net/content/repositories/snapshots/</url><layout> Default</layout></repository><repository><id>spring.test-mvc</id><url>http ://repo.springsource.org/libs-milestone</url></repository><repository><id>repo1</id ><name&Gt;repo1</name><url>http://repo1.maven.org/maven2</url></repository><repository> <id>jboss-cache</id><name>jboss-cache</name><url>http://repository.jboss.org/ Maven2</url></repository><repository><id>mvnsearch</id><name>mvnsearch Maven repository</name><url>http://www.mvnsearch.org/maven2</url></repository>< Repository><id>ibiblio</id><name>ibiblio Maven repository</name><url>http:// Www.ibiblio.org/maven2</url></repository><repository><id>mirrors.ibiblio</id> <name>mirrors.ibiblio Maven repository</name><url>http://mirrors.ibiblio.org/pub/mirrors/ maven2</url></repository></repositories><dependencies><!--Tomcat Servlet API-- <dependency><groupid>javax.servlet</groupid><artifactid>javax.servlet-api</ artifactid><version>3.1.0</version></dependency><dependency><groupid>org.glassfish.jersey.containers</ groupid><artifactid>jersey-container-grizzly2-servlet</artifactid><version>2.13</ Version></dependency><dependency><groupid>org.glassfish.jersey.containers</groupid> <artifactid>jersey-container-servlet-core</artifactid><version>2.13</version></ Dependency><dependency><groupid>org.glassfish.jersey.media</groupid><artifactid> jersey-media-json-jackson</artifactid><version>2.13</version></dependency><!-- Required only if you are using Jax-rs Client--><dependency><groupid>org.glassfish.jersey.core</ groupid><artifactid>jersey-client</artifactid><version>2.13</version></ dependency><!--MongoDB--><dependency><groupid>org.mongodb</groupid><artifactid >mongo-java-driver</artifactiD><version>2.12.4</version></dependency></dependencies><build><finalname >jerseyUserDemo</finalName></build></project>

Second, the user entity class code is as follows

Package Model;import java.io.Serializable; public class User implements serializable{/** * */private static final long serialversionuid = 1l;private String id;priv Ate string Username;private string Phone;public User () {}public User (string ID, string userName, String phone) {super (); thi S.id = Id;this.username = Username;this.phone = phone;} Public String GetId () {return ID;} public void SetId (String id) {this.id = ID;} Public String GetUserName () {return userName;} public void Setusername (String userName) {this.username = UserName;} Public String Getphone () {return phone;} public void Setphone (string phone) {this.phone = phone;} @Overridepublic String toString () {return "User [id=" + ID + ", u Sername= "+ UserName +", phone= "+ Phone +"] ";} @Overridepublic int hashcode () {final int prime = 31;int result = 1;result = Prime * result + (id = = NULL)? 0:ID.HASHC Ode ()); return result;} @Overridepublic boolean equals (Object obj) {if (this = = obj) return true;if (obj = = null) return false;if (GetCLass ()! = Obj.getclass ()) return false; User other = (user) obj;if (id = null) {if (other.id! = null) return false;} else if (!id.equals (other.id)) return False;re Turn true;}}

Third, the Userresource class code is as follows, the path of the access is established here.

Package Resource;import Java.util.list;import Javax.inject.singleton;import javax.ws.rs.consumes;import Javax.ws.rs.delete;import javax.ws.rs.get;import javax.ws.rs.post;import Javax.ws.rs.put;import Javax.ws.rs.Path; Import Javax.ws.rs.pathparam;import Javax.ws.rs.produces;import model. User;import service. UserService; @Singleton @path ("/users") public class Userresource {@GET @produces ({"Application/json", "application/ XML "}) public list<user> getmyresources () {list<user> users = Userservice.getusers (); return users;} @GET @path ("/list") @Produces ({"Application/json", "Application/xml"}) public list<user> getlistofusers () {list <User> users = Userservice.getusers (); return users;} @GET @path ("/{id}") @Produces ({"Application/json"}) public User GetUser (@PathParam ("id") String ID) {User u= Userservice.getuserbyid (ID); return u;} @PUT//@Path ("/ids/{id}") @Consumes ({"Application/json", "Application/xml"}) public void Putuser (user user) { Userservice.updateuser (user); } @POST//@Path ("/ids/{id}") @Consumes ({"Application/json", "Application/xml"}) public void Postuser (user user) { Userservice.adduser (user); } @DELETE @path ("/{id}") public void DeleteUser (@PathParam ("id") String ID) {Userservice.deluserbyid (id);}}

Iv. MyApplication class, by loading the userresourcer into the application

Package Main;import Java.util.hashset;import Java.util.set;import javax.ws.rs.applicationpath;import Javax.ws.rs.core.application;import Resource. userresource;/** * @author Pavel Bucek (Pavel.bucek at oracle.com) */@ApplicationPath ("/") public class MyApplication Exte NDS Application {    @Override public    set<class<?>> getclasses () {        final set<class<?> > classes = new hashset<class<?>> ();        Register Root Resource        Classes.add (userresource.class);        return classes;}    }

The App class is the entry for the entire project, and can be started by running the main function in the class.

After starting, you can test by running the client test code in the TestClient class. I continue to post the code.

The code is as follows:

Package Main;import Java.io.ioexception;import Java.net.uri;import java.util.hashmap;import java.util.Map;import Java.util.logging.level;import Java.util.logging.logger;import Org.glassfish.grizzly.http.server.HttpServer; Import Org.glassfish.jersey.grizzly2.servlet.grizzlywebcontainerfactory;import Org.glassfish.jersey.server.serverproperties;import Org.glassfish.jersey.servlet.servletcontainer;import Resource. userresource;/** * @author Pavel Bucek (Pavel.bucek at oracle.com) */public class App {private static final URI Base_u    RI = Uri.create ("http://localhost:8080/webapp/");    public static final String Root_path = "users"; public static void Main (string[] args) {try {map<string, string> initparams = new HashMap            <string, string> ();                        Initparams.put (Serverproperties.provider_packages, UserResource.class.getPackage (). GetName ()); Final Httpserver server = Grizzlywebcontainerfactory.create (Base_uri, ServletcontaIner.class, InitParams); System.out.println (String.Format ("Application started.%ntry out%s%s%nhit Enter to stop it ...", Base_ur            I, Root_path));            System.in.read ();        Server.shutdownnow ();        } catch (IOException ex) {Logger.getlogger (App.class.getName ()). log (Level.severe, NULL, ex); }    }}

VI. testclient test Client code:

Package Client;import Javax.ws.rs.client.client;import Javax.ws.rs.client.clientbuilder;import Javax.ws.rs.client.entity;import Javax.ws.rs.client.webtarget;import Javax.ws.rs.core.mediatype;import Javax.ws.rs.core.response;import model. User;import com.fasterxml.jackson.jaxrs.json.jacksonjsonprovider;/** * * @author Zhongtianyi * */public class testclient {private static String Serveruri = "Http://localhost:8080/webapp";/** * @param args */public static void main (S Tring[] args) {User user = new User ("006", "Tianyi", "12355123891"), AddUser (user), GetAllUsers (), user = new User ("006", "Ti Anyi "," 33 "); String id = user.getid (); updateUser (user); Getuserbyid (ID); GetAllUsers ();d eluser (ID); GetAllUsers ();} /** * Add user */private static void addUser (user user) {System.out.println ("Add Users adduser****"); Client client = Clientbuilder.newclient (); Webtarget target = client.target (Serveruri + "/users"); Response Response = Target.request (). Buildpost (entity.entity (user, Mediatype.application_json)). Invoke (); Response.close ();} /** * Delete user */private static void Deluser (String id) {System.out.println ("Delete User * * * * * * * * *"); Client client = Clientbuilder.newclient (); Webtarget target = client.target (Serveruri + "/users/" + ID); Response Response = target.request (). Delete (); Response.close ();} /** * Modify user */private static void updateUser (user user) {System.out.println ("Modify user updateuser****"); Client client = Clientbuilder.newclient (); Webtarget target = client.target (Serveruri + "/users"); Response Response = Target.request (). Buildput (entity.entity (user, Mediatype.application_json)). Invoke (); Response.close ();} /** * Query user */private static void Getuserbyid (String id) {System.out.println ("query user based on ID") based on ID; Client client = Clientbuilder.newclient (). Register (Jacksonjsonprovider.class);//register JSON support Webtarget target = Client.target (Serveruri + "/users/" + ID); Response Response = Target.request (). get (); User user = Response.readentity (user.class); System.out.println (User.getid () + user.getusername ()); Response.closE ();} /** * Query all users */private static void GetAllUsers () {System.out.println ("Query all getallusers****"); Client client = Clientbuilder.newclient (); Webtarget target = client.target (Serveruri + "/users"); Response Response = Target.request (). get (); String value = response.readentity (String.class); System.out.println (value); Response.close (); Close Connection}}

Run the results such as: After running the App class entrance, the program listens to 8080 ports, we will find that we do not need Tomcat and other web containers can easily create Web services, concise and fast.

The following figure is run out of the TestClient test client output results, additions and deletions to check the output

The following figure is a successful addition of data after running add data in MONGO.
