RESTful web services JAXRS json example using jersey

In this post, we will see RESTful web services JAXRS json example using jersey.

In previous post, we have created a very simple Restful web services(JAXRS) using jersey which returns xml. In this post, we will see Restful web services(JAXRS) using jersey which will return json as response.

Here are steps to create a simple Restful web services(JAXRS)  using jersey which will return json.
1) Create a dynamic web project using maven in eclipse named “JAXRSJsonExample”

Jersey internally uses Jackson for Json Handling, so it will be used to marshal pojo objects to JSON.

Now create pom.xml as follows:

Application configuration:

3) create web.xml as below:

Create CountryRestService

5) Create a controller named “”

@Path(/your_path_at_class_level) : Sets the path to base URL + /your_path_at_class_level. The base URL is based on your application name, the servlet and the URL pattern from the web.xml” configuration file.

@Path(/your_path_at_method_level): Sets path to base URL + /your_path_at_class_level+ /your_path_at_method_level

@Produces(MediaType.APPLICATION_JSON[, more-types ]): @Produces defines which MIME type is delivered by a method annotated with @GET. In the example text (“text/json”) is produced.

6) It ‘s time to do maven build.

Right click on project -> Run as -> Maven build

7) Provide goals as clean install (given below) and click on run

Run the application

8) Right click on project -> run as -> run on server
Select apache tomcat and click on finish
9) Test your REST service under: “http://localhost:8080/JAXRSJsonExample/rest/countries”.
