Description
Sometimes, the class to use as the target for @Argument might not have a setter for all its properties. E.g.
public class PriceValuation4 {
// ...
protected List<ActiveOrHistoricCurrencyAndAmount> ttlNAV;
protected List<UnitPrice15> pricDtls;
protected List<ValuationStatistics3> valtnSttstcs;
// ...
public PriceValuation4 addTtlNAV(ActiveOrHistoricCurrencyAndAmount ttlNAV) {
this.getTtlNAV().add(ttlNAV);
return this;
}
public PriceValuation4 addPricDtls(UnitPrice15 pricDtls) {
this.getPricDtls().add(pricDtls);
return this;
}
public PriceValuation4 addValtnSttstcs(ValuationStatistics3 valtnSttstcs) {
this.getValtnSttstcs().add(valtnSttstcs);
return this;
}
}Especially when the class is from a third-party library, which is my case here.
Is it possible to fall back to using the direct-field-access approach when the proper Setter cannot be found?
Would the following code change make sense?
public class GraphQlArgumentBinder {
// ...
private Object bindMapToObjectViaSetters(
Map<String, Object> rawMap, Constructor<?> constructor, ResolvableType ownerType,
ArgumentsBindingResult bindingResult) {
Object target = BeanUtils.instantiateClass(constructor);
BeanWrapper beanWrapper = PropertyAccessorFactory.forBeanPropertyAccess(target);
for (Map.Entry<String, Object> entry : rawMap.entrySet()) {
// ...
}
}
}To:
import org.springframework.data.util.DirectFieldAccessFallbackBeanWrapper;
public class GraphQlArgumentBinder {
// ...
private Object bindMapToObjectViaSetters(
Map<String, Object> rawMap, Constructor<?> constructor, ResolvableType ownerType,
ArgumentsBindingResult bindingResult) {
Object target = BeanUtils.instantiateClass(constructor);
/*========================================================================*/
DirectFieldAccessFallbackBeanWrapper beanWrapper = new DirectFieldAccessFallbackBeanWrapper(target);
/*========================================================================*/
for (Map.Entry<String, Object> entry : rawMap.entrySet()) {
// ...
}
}
}
