i wrote this app with eclipse and it works. But when i deploy it as standalone/console application, it cannot find StartApp bean i've injected. here's the codes:
main app:
@Component
public class StartApp {
@Autowired
private Processor proc;
public StartApp() {
System.out.println("Starting App!");
}
private void say() {
proc.say();
}
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
StartApp app = ctx.getBean(StartApp.class);
app.say();
}
}
service:
@Service
public class Processor {
public Processor() {
System.out.println("Processor initialized!");
}
public void say() {
System.out.println("hello!");
}
}
and applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd">
<context:component-scan base-package="test.spring.desktop"/>
</beans>
i did put all spring libraries and logger including slf4j libraries. and for console command i put these:
java -cp lib/*:lib/spring-3.1/*:test-spring-desktop.jar test.spring.desktop.StartApp
then i got these error message:
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [test.spring.desktop.StartApp] is defined: expected single bean but found 0:
