Ho un bean che voglio iniettare con un elenco denominato utilizzando lo spazio dei nomi Spring util <util:list id="myList">
ma Spring sta cercando invece una raccolta di bean di tipo String. Il mio test non funzionante è:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class ListInjectionTest {
@Autowired @Qualifier("myList") private List<String> stringList;
@Test public void testNotNull() {
TestCase.assertNotNull("stringList not null", stringList);
}
}
Il mio contesto è:
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<util:list id="myList">
<value>foo</value>
<value>bar</value>
</util:list>
</beans>
Ma capisco
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [java.lang.String] found for dependency [collection of java.lang.String]: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Il che mi lascia piuttosto perplesso perché immaginavo che questo sarebbe stato il modo in cui avrebbe dovuto funzionare.
