Damian Nowak commented on WICKET-1143:
--------------------------------------
I managed to create some almost-working Injector for both Java EE and Spring.
EJBs and Spring Beans get injected with this.
Almost-working because I get serialization exceptions - I don't know why Wicket
needs the class serializable as the classes from Java EE injector and Spring
injector are not and they work.
in Application.init():
{noformat}
addComponentInstantiationListener(new SpringComponentInjector(this));
addComponentInstantiationListener(new JavaEEComponentInjector(this,
createNamingStrategy()));
final SpringAndJavaEeInjector springAndJavaEeInjector = new
SpringAndJavaEeInjector(this, new StandardJndiNamingStrategy()); // I use my
own naming strategy, StandardJndiNamingStrategy is the default
InjectorHolder.setInjector(springAndJavaEeInjector);

Serializable {
private final SpringAndJavaEeFieldValueFactory factory;
public SpringAndJavaEeInjector(final WebApplication webApplication,
final IJndiNamingStrategy namingStrategy) {
JavaEEProxyFieldValueFactory javaEeFactory = new
JavaEEProxyFieldValueFactory(namingStrategy);
AnnotProxyFieldValueFactory springFactory = new
AnnotProxyFieldValueFactory(new ISpringContextLocator() {
@Override
public ApplicationContext getSpringContext() {
return
WebApplicationContextUtils.getRequiredWebApplicationContext(webApplication.getServletContext());
}
}, true);
factory = new SpringAndJavaEeFieldValueFactory(javaEeFactory,
springFactory);
}
@Override
protected IFieldValueFactory getFieldValueFactory() {
return factory;
}
private static class SpringAndJavaEeFieldValueFactory implements
IFieldValueFactory {
private final JavaEEProxyFieldValueFactory javaEeFactory;
private final AnnotProxyFieldValueFactory springFactory;
public
SpringAndJavaEeFieldValueFactory(JavaEEProxyFieldValueFactory javaEeFactory,
AnnotProxyFieldValueFactory springFactory) {
this.javaEeFactory = javaEeFactory;
this.springFactory = springFactory;
}
@Override
public Object getFieldValue(Field field, Object fieldOwner) {
try {
final Object fieldValue =
javaEeFactory.getFieldValue(field, fieldOwner);
if (fieldValue == null) {
throw new RuntimeException();
}
return fieldValue;
} catch (Exception e) {
return springFactory.getFieldValue(field,
fieldOwner);

final boolean supportsField =
javaEeFactory.supportsField(field);

If anyone is able to correct it so that no serialization exceptions are thrown,
feel free.
