In this example we are using spring-boot-starter and commons-collections dependencies. We are also changing versions in pom properties.
package com.logicbig.example;
import org.apache.commons.collections.Bag;
import org.apache.commons.collections.bag.HashBag;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class ApplicationExample {
@Bean
public MyBean myBean () {
return new MyBean();
}
public static void main (String[] args) {
ApplicationContext ctx =
SpringApplication.run(ApplicationExample.class, args);
MyBean bean = ctx.getBean(MyBean.class);
bean.doSomething();
}
private static class MyBean {
public void doSomething () {
Bag bag = new HashBag();
bag.add("ONE", 6);
System.out.println("Doing something in MyBean");
System.out.println(bag);
}
}
}
