Example 1
private Object resolveResource(InjectionPoint injectionPoint) {
    Resource resource = getResourceAnnotation(injectionPoint);
    if (resource == null) {
        throw new IllegalArgumentException("No @Resource annotation found on " + injectionPoint);
    }
    if (injectionPoint.getMember() instanceof Method && ((Method) injectionPoint.getMember()).getParameterTypes().length != 1) {
        throw new IllegalArgumentException(
                "Injection point represents a method which doesn't follow JavaBean conventions (must have exactly one parameter) " + injectionPoint);
    }
    String name;
    if (!resource.lookup().equals("")) {
        name = resource.lookup();
    } else {
        name = getResourceName(injectionPoint);
    }
    return resources.get(name);
}
 
Example 2
public ResourceElement(Member member, AnnotatedElement ae, @Nullable PropertyDescriptor pd) {
	super(member, pd);
	Resource resource = ae.getAnnotation(Resource.class);
	String resourceName = resource.name();
	Class<?> resourceType = resource.type();
	this.isDefaultName = !StringUtils.hasLength(resourceName);
	if (this.isDefaultName) {
		resourceName = this.member.getName();
		if (this.member instanceof Method && resourceName.startsWith("set") && resourceName.length() > 3) {
			resourceName = Introspector.decapitalize(resourceName.substring(3));
		}
	}
	else if (embeddedValueResolver != null) {
		resourceName = embeddedValueResolver.resolveStringValue(resourceName);
	}
	if (Object.class != resourceType) {
		checkResourceType(resourceType);
	}
	else {

		resourceType = getResourceType();
	}
	this.name = (resourceName != null ? resourceName : "");
	this.lookupType = resourceType;
	String lookupValue = resource.lookup();
	this.mappedName = (StringUtils.hasLength(lookupValue) ? lookupValue : resource.mappedName());
	Lazy lazy = ae.getAnnotation(Lazy.class);
