Instead of being able to override properties in any beans, this variant of PropertyOverrideConfigurer restricts property overriding to just 1 specified bean.

BeanPropertyOverrideConfigurer.java

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.config.PropertyOverrideConfigurer;

public class BeanPropertyOverrideConfigurer extends PropertyOverrideConfigurer {

	private String beanName;

	public String getBeanName() {
		return beanName;
	}

	public void setBeanName(String beanName) {
		this.beanName = beanName;
	}

	@Override
	protected void processKey(ConfigurableListableBeanFactory factory, String key, String value)
			throws BeansException {
		applyPropertyValue(factory, beanName, key, value);
	}

}
