Bean Validation

Hi All,

I am new to Spring Framework. I was trying to do a Simple Validation on one of my bean. Since i don't want to use the MVC frmamework can somebody help me out in doing that.

Here is my code.

package example;

import org.springframework.context.ResourceLoaderAware;
import org.springframework.core.io.ResourceLoader;


public class Person implements ResourceLoaderAware {

private String name;
private int age;

public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public void setResourceLoader(ResourceLoader arg0) {
}

}


package example;

import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;

public class PersonValidator implements Validator {

public boolean supports(Class clzz) {
return Person.class.equals(clzz);
}

public void validate(Object obj, Errors e) {
ValidationUtils.rejectIfEmpty(e, "name", "name.empty");
Person p = (Person)obj;
if (p.getAge() < 0) {
e.rejectValue("age", "negativevalue");
} else if (p.getAge() > 110) {
e.rejectValue("age", "tooold");
}
}

}


<bean id="person" class="example.Person">
<property name="name">
<value> Amit Kaushik </value>
</property>
<property name="age">
<value> -28 </value>
</property>
<property name="validator">
<bean class="example.PersonValidator"/>
</property>

</bean>


I want to use PersonValidator Class to validate Person's class properties. Do i need to call explicitly the PeronValidator method in to Perosn's setResourceLoader method or is there any other way of doing this.

Any help will be appreciated.

Thanks,
Amit
