Create this main App class
package io.javabrains.springbootstarter;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class CourseApiApp {
public static void main(String[] args) {
SpringApplication.run(CourseApiApp.class, args);
}
}
and these 2 controller classes
package io.javabrains.springbootstarter.hello;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@RequestMapping("/hello")
public String sayHi() {
return "Hi";
}
}
package io.javabrains.springbootstarter.topic;
import java.util.Arrays;
import java.util.List;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TopicController {
@RequestMapping("/topics")
public List getAllTopics() {
return Arrays.asList(
new Topic("a", "aa", "aaa"),
new Topic("b", "bb", "bbb")
);
}
}
where Topic is
package io.javabrains.springbootstarter.topic;
public class Topic {
private String id;
private String name;
private String description;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Topic(String id, String name, String description) {
super();
this.id = id;
this.name = name;
this.description = description;
}
public Topic() {
}
}
Run the main App (this will start the embedded tomcat), enter in the browser this
http://localhost:8080/topics
and you get a great JSON response....
[{"id":"a","name":"aa","description":"aaa"},{"id":"b","name":"bb","description":"bbb"}]
