The @Qualifier annotation in Spring is used to differentiate a bean among the same type of bean objects.

If we have more than one bean of the same type and want to wire only one of them then use the @Qualifier annotation along with @Autowired to specify which exact bean will be wired.

If we don't use this annotation in the given project then we get an error like:

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type

The @Required annotation applies to bean property setter methods and it indicates that the affected bean property must be populated in XML configuration file at configuration time. Otherwise, the container throws a BeanInitializationException exception

public class Student {
private Integer age;
private String name;

@Required
public void setAge(Integer age) {
this.age = age;
}
public Integer getAge() {
return age;
}

@Required
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}

import org.springframework.context.annotation.*;

@Configuration
public class HelloWorldConfig {
@Bean
public HelloWorld helloWorld(){
return new HelloWorld();
}
}
