Get every bean from bean.xml file-CodePudding

I have an xml file with beans which look like this:

<bean  id="1">
        <property name="first_name" value="Jillian"/>
        <property name="last_name" value="Palethorpe"/>
        <property name="email" value="[email protected]"/>
        <property name="company_name" value="Layo"/>
</bean>

It has up to 30 beans with class person and id from 1 to 30.

Now i want to print them I know that I could do this like that:

@SpringBootApplication
@ImportResource("classpath:beans.xml")
public class Main {
public static void main(String[] args) {
    
    ApplicationContext applicationContext = SpringApplication.run(Main.class, args);
    Person first = applicationContext.getBean("1", Person.class);
    Person second = applicationContext.getBean("2", Person.class);
    System.out.println(first);
    System.out.println(second);
}

}

But is there a better way to get all of the "beans" or persons from this xml file?

CodePudding user response：

There is a getBeansOfType() method in the ApplicationContext which can return all beans of a given type. The beans will be retuned as a map which the key is the name of the bean while the value is the bean instance.

Map<String, Person> beans = applicationContext.getBeansOfType(Person.class);

Person person1 = beans.get("1"); 
Person person2 = beans.get("2");

List<Person> allPersons = new ArrayList<>(beans.values());
