我有一个应用程序，但无法让它在 Eclipse 或其他地方运行。
这是我的课：
package fr.aaa;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;
@Component
public class Computation {
public Computation() {
}
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml");
Computation computer = context.getBean(Computation.class);
}
}
和我的 applicationContext.xml 文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<property name="locations">
<list>
<value>classpath:configuration.properties</value>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
我得到这个例外：
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [fr.aaa.Computation] is defined: expected single bean but found 0:
我在这里错过了什么吗？
