Please support "isPrimary" for @SpringBean

Key: WICKET-2771
URL: https://issues.apache.org/jira/browse/WICKET-2771
Project: Wicket
Issue Type: Improvement
Components: wicket-spring
Reporter: Kathrin Baumgartner
Our application must be adaptable for customer needs. We therefore need to be
able to inject customer specific services. Since all our services are
autowired, we could solve this by using the "primary" attribute.
Our propsal is to patch SpringBeanLocator:
private final String getBeanNameOfClass(ApplicationContext ctx, Class< ? >
clazz) {
// get the list of all possible matching beans
List<String> names = new
ArrayList<String>(Arrays.asList(BeanFactoryUtils
.beanNamesForTypeIncludingAncestors(ctx, clazz)));
Iterator<String> it = names.iterator();
// filter out beans that are not condidates for autowiring
while (it.hasNext()) {
final String possibility = it.next();
if (BeanFactoryUtils.isFactoryDereference(possibility) ||
possibility.startsWith("scopedTarget.")) {
it.remove();
}
}
if (names.isEmpty()) {
throw new IllegalStateException("bean of type [" +
clazz.getName() + "] not found");
} else if (names.size() > 1) {
///////////////////////// add this
///////////////////////////////////////////////
for (String name : names){
BeanDefinition beanDef =
((AbstractApplicationContext)ctx).getBeanFactory().getBeanDefinition(name);
if(((AbstractBeanDefinition)beanDef).isPrimary()){
return name;
}
}
//////////////////////////////////////////////////////////////////////////////////////
// found no match
StringBuilder msg = new StringBuilder();
msg.append("more then one bean of type [");
msg.append(clazz.getName());
msg.append("] found, you have to specify the name of the bean
");
msg.append("(@SpringBean(name=\"foo\")) in order to resolve
this conflict. ");
msg.append("Matched beans: ");
msg.append(Strings.join(",", names.toArray(new String[0])));
throw new IllegalStateException(msg.toString());
}
else{
return names.get(0);
}
}
