Question

I’m interested in reusing this logic for something I’m working on.

Given

<bean name="myBeanWithSetXyz" class="com.blah.Something/>
 <property name="xyz" value="3"/>

is there a spring class someplace that figures out setXyz() is an int, and sets it on an instance of the bean?

Or perhaps some other utility? Yeah, I could write it myself, but I’m a fan of reuse.

DirectFieldAccessor and BeanWrapperImpl are your most likely candidates.

ConfigurablePropertyAccessor fieldAccessor = new DirectFieldAccessor (someObject);
beanWrapper.setPropertyValue(fieldName, 
   fieldAccessor.convertForProperty(value, fieldName) );


ConfigurablePropertyAccessor beanWrapper = new BeanWrapperImpl(someObject);
beanWrapper.setPropertyValue(propertyName, 
   beanWrapper.convertForProperty(value, propertyName) );
