正确配置了context:component-scan，但eclipse仍然提示No bean named 'forBeanAnnotation' availa

[Tseward]

这是bean

package com.spring.demo.beanannotation;

import org.springframework.stereotype.Component;

@Component("forBeanAnnotation")
public class ForBeanAnnotation {

	public ForBeanAnnotation() {
	}

	public void say(){
		System.out.println("hello");
	}
}

这是测试类

package com.spring.test.beanannotation;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;

import com.spring.demo.beanannotation.ForBeanAnnotation;
import com.spring.test.base.UnitTestBase;

@RunWith(BlockJUnit4ClassRunner.class)
public class TestBeanAnnotation  extends UnitTestBase{

	public TestBeanAnnotation() {
		super("classpath:spring-annotation.xml");
	}
	
	@Test
	public void testbeanAnnotaion(){
		ForBeanAnnotation beanAnnotaion = super.getBean("forBeanAnnotation");
		beanAnnotaion.say();
	}
	
}

这是配置文件

<?xml version="1.0" encoding="UTF-8"?>
<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/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.spring.test.beanannotation"/>

</beans>

运行测试类后eclipse提示
