最佳答案
这是我的代码:
public class Main {
public static void main(String[] args) {
Main p = new Main();
p.start(args);
}
@Autowired
private MyBean myBean;
private void start(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("META-INF/config.xml");
System.out.println("my beans method: " + myBean.getStr());
}
}
@Service
public class MyBean {
public String getStr() {
return "string";
}
}
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<context:component-scan base-package="mypackage"/>
</beans>
为什么这个不工作? 我得到了 NullPointerException
。可以在绿色软体中使用自动装配吗?
