Custom editor configurer

[strbuf]

How do I make a custom editor configurer to convert an object type to a String?
I already did what is written here, it gave me these error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'net.streambuffer.kelurahan.model.Perumahan' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyAccessExceptionsException: PropertyAccessExceptionsException (1 errors); nested propertyAccessExceptions are: [org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.lang.String] to required type [net.streambuffer.kelurahan.model.Rt] for property 'rt']

This is my kelurahan-servlet.xml

<beans>
    <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
  	<property name="customEditors">
    <map>
      <entry key="net.streambuffer.kelurahan.model.Rt">
        <bean class="net.streambuffer.kelurahan.logic.RtPropsEditor">
          <property name="format" value="upperCase"/>
        </bean>
      </entry>
    </map>
  	</property>
	</bean>
	
</beans>

And my applicationContext.xml

<beans>
    <bean id="perumahan" parent="baseTransactionProxy">
    <property name="target">
		<bean class="net.streambuffer.kelurahan.dao.PerumahanDao">
			<property name="sessionFactory" ref="sessionFactory" />
		</bean>
	</property>
	<property name="rumahRt">
		<bean class="net.streambuffer.kelurahan.model.Perumahan">
			<property name="rt"><value>rt</value></property>
		</bean>
	</property>
    </bean>
</beans>

My net.streambuffer.kelurahan.logic.RtPropsEditor:

public class RtPropsEditor extends PropertyEditorSupport {
    private String format;

    public void setFormat(String format) {
        this.format = format;
    }
    
	public void setAsText(Integer text) throws IllegalArgumentException {
	    Rt rt=new Rt(text);
	    setValue(rt);
	}

	public String getAsText() {
		Object value = getValue();
		if (value != null) {
			return value.toString();
		} else {
			return "";
		}
	}
}

Could anyone give me a clue of what I need to do?
Thanks in advance.

I've got it fixed now, but what made me curious is that Hibernate forces Rt to have default constructor.

[Costin Leau]

See HB reference documentation - HB uses CGLib which requires a default constructor (in order to do clazz.newInstance()).

[strbuf]

Is there anyway I could disable this since I have to write

public myConstructor(){
   this.id=getId();
}

I'm not sure whether that is the right way :-D

[Costin Leau]

What are you trying to do? why do you set your id using getId() - isn't the id already set (that's what getId() does no?)

[strbuf]

I'm making a default constructor. I've read hibernate doc saying that I should have a constructor with at least package visibility. But I still don't know what to write in a default constructor.

[Costin Leau]

But I still don't know what to write in a default constructor.

Then maybe you should read the java tutorial. A default constructor exists by default in every class if you don't declare one. A constructor can be empty but that's something you should know before getting into HB, IMO.
