The annotation #Bean is disallowed for this location error - spring

Question

I read in a book that whenever we want a Java-based configuration and want define a bean we use #Bean annotation. But when I did that I got the error: The annotation #Bean is disallowed for this location. My bean is:
package com.mj.cchp.bean;
import javax.validation.constraints.Digits;
import javax.validation.constraints.NotNull;
import org.springframework.context.annotation.Bean;
import com.mj.cchp.annotation.Email;
#Bean
public class UserBean {
#NotNull
#Email
private String email;
#NotNull
private String firstName;
#NotNull
private String lastName;
#Digits(fraction = 0, integer = 10)
private String phoneNo;
#NotNull
private String role;
public String getEmail() {
return email;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public String getPhoneNo() {
return phoneNo;
}
public String getRole() {
return role;
}
public void setEmail(String email) {
this.email = email;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public void setPhoneNo(String phoneNo) {
this.phoneNo = phoneNo;
}
public void setRole(String role) {
this.role = role;
}
}

Answer 1

The #Bean annotation is to define a Bean to be loaded in the Spring container. it is similar to the xml config of specifying
<bean id="myId" class="..."/>
This should be used in a Configuration file(java). Which is similar to your applicationContext.xml
#Configuration
#ComponentScan("...")
public class AppConfig{
#Bean
public MyBean myBean(){
return new MyBean();
}
}
The #Bean, #Configuration and other newly introduced annotations will do exactly what you do in an Xml config.

Answer 2

The #Bean annotation tells Spring that a method annotated with #Bean will return an object that should be registered as a bean in the Spring application context.
So you need a UserBeanConfig class that will be annotated using #Configuration that will have a method that create the new bean.
#Configuration
public class UserBeanConfig {
#Bean
public UserBean userBean(){
return new UserBean();
}
}
From my point of view Spring is not designed to construct simple Domain object.
You should use Spring to bootstrap the dependencies of Service/DAO etc.
So I suggest avoiding spring for domain objects.
