Sometime we need to delete record from our application , in this case we develop delete rest api using delete method. Before start learning jax rs delete example i consider you have idea for jax-rs api implementation .Now follow these step for make a rest application using delete method .
JAX-RS DELETE Example
Step 1: create handle class and define path , method and response. We will create delete method in handler .
UserHandler.java
package com.javaproficiency.jerseydemo.demo;
import javax.ws.rs.DELETE;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
@Path("/user")
public class UserHander {
/*
Use @DELETE annotation here
*/
@DELETE
public Response getMessage(){
String message="Jersey Hello By Java Proficiency";
return Response.status(Status.OK).entity(message).build();
}
}Step 2. configure web.xml file as
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"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>JerseyDemo</display-name>
<servlet>
<servlet-name>RestServices</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.javaproficiency.jerseydemo.demo</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RestServices</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>Step 3. Add dependency in pom.xml file as bellow.
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

Step 5: Run Project and Hit url
How to decide url:
HostName:PortNumber/ProjectName/+Your Decide Path
Example:
http://localhost:8080/JerseyDemo/rest/user
