Java – using wildfly 8’s simple rest API

First of all, I am a novice in this environment I've developed Java before, but I'm not an application server I've never done this before. I've never used JBoss or wildfly before

I have been able to set up and run the wildfly server in 127.0 0.1:9990 access it When I deploy War file, the server does not respond, I can't access the URL

The wildfly server did declare that my deployment was successful and active, and then I tried to access: 127.0 0.1:8080 / recapp API / rest / message / test, I get 404 (page error not found)

I'm using maven, so first, my POM xml：

<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/xsd/maven-4.0.0.xsd">

  <groupId>com.test.recapp.rest</groupId>
  <artifactId>RECAPP-API</artifactId>
  <version>0.0.1-SNAPSHOT</version>

    <plugins>
      <plugin>

        <configuration>
          <source>1.7</source>
          <target>1.7</target>
        </configuration>
      </plugin>
    </plugins>
  </build>
  <dependencies>
    <dependency>

    </dependency>
    <dependency>

        <artifactId>resteasy-jackson-provider</artifactId>
        <version>3.0.6.Final</version>
    </dependency>
  </dependencies>
</project>

My jsonservice java：

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;

@Path("/message")
public class JSONService {

    @GET
    @Path("/{param}")
    @Produces("application/json")
    public Response printMessage(@PathParam("param") String msg) {
        String result = "Restful example: " + msg;
        return Response.status(200).entity(result).build();
    }

}

Finally, my web xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee"

    id="WebApp_ID" version="3.0">
  <display-name>RECAPP-API</display-name>

  <context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>true</param-value>
  </context-param>

  <context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
  </context-param>

  <listener>
    <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
  </listener>

  <servlet>
    <servlet-name>resteasy-servlet</servlet-name>
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>resteasy-servlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>


</web-app>

Thanks for your help.

Solution

The best way to start quickly is to use this dependency

<dependency>
  <groupId>javax</groupId>
  <artifactId>javaee-api</artifactId>
  <version>7.0</version>
  <scope>provided</scope>
</dependency>

And add a class that extends the application class

@ApplicationPath("rest")
public class ConfigApp extends Application {
   public ConfigApp(){
   }
}

nothing more. No web XML changes (only if web. XML is not required)

And use host: port / < warname > / rest / < endpoint Path > to access your rest endpoint
