spring boot @restcontroller dependency code example

Example 1: spring @restcontroller

package com.example.restservice;

import java.util.concurrent.atomic.AtomicLong;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

	private static final String template = "Hello, %s!";
	private final AtomicLong counter = new AtomicLong();

	@GetMapping("/greeting")
	public Greeting greeting(@RequestParam(value = "name", defaultValue = "World") String name) {
		return new Greeting(counter.incrementAndGet(), String.format(template, name));
	}
}Copy

Example 2: maven dependencies for rest api

This include all basic component of RestAssured

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>4.3.1</version>
    <scope>test</scope>

</dependency>

If we want to use serialization , de-serialization
we will need Jackson-Databind

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.11.2</version>
</dependency>

If we need Json schema validation

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>json-schema-validator</artifactId>
    <version>4.3.1</version>
    <scope>test</scope>
</dependency>

JsonPath and XmlPath is already included in the
RestAssured dependency, If you want to work with
JsonPath and XmlPath outside context of RestAssured
, you may also add below 2 dependencies.
It will enable you to directly work with
json file or xml file and use JsonPath and XmlPath.

<dependency>
      <groupId>io.rest-assured</groupId>
      <artifactId>json-path</artifactId>
      <version>4.3.1</version>
      <scope>test</scope>
</dependency>

<dependency>
      <groupId>io.rest-assured</groupId>
      <artifactId>xml-path</artifactId>
      <version>4.3.1</version>
      <scope>test</scope>
</dependency>
