NoSuchBeanDefinitionException

异常信息如下：

我的application-channel-test.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<bean id="zybCoreBS" class="com.tansun.scf.zyb.intf.core.service.impl.ZybCoreBSImpl">
<property name="bussCommonBS">

</property>
</bean>

<bean id="zybCmsBS" class="com.tansun.scf.zyb.intf.cms.service.impl.ZybCmsBSImpl">

单元测试调zybCmsBS中的方法可以跑，但是当调到bussCommonBS的方法时报空指针异常，已经注入了还报这个说不过去，于是测试zybCoreBS，没想到直接报错如上，再测试直接调bussCommonBS，报空指针异常，分析了半天也不知道是什么原因，有大神可以指点下么？

我的Test类如下：

public class Test01 extends LoadPropertis {

// public TestAction testAction;
private IZybCmsBS zybCmsBS;
// private IBussCommonBS bussCommonBS;
private IZybCoreBS zybCoreBS;

protected void setUp() throws Exception{
super.setUp();
zybCmsBS = (IZybCmsBS)this.getBean("zybCmsBS");
// bussCommonBS = (IBussCommonBS)this.getBean("bussCommonBS");
zybCoreBS = (IZybCoreBS)this.getBean("zybCoreBS");
}

protected void tearDown()throws Exception{
super.tearDown();

}

public void test01() {
//BlacklistInVO blacklistInVO = new BlacklistInVO();
CurrAccoInVo currAccoInVo = new CurrAccoInVo();
try {
// zybCmsBS.blacklistInfoSync(blacklistInVO);
zybCoreBS.currAccoQuery(currAccoInVo);
} catch (Exception e) {
System.out.println("失败");
}
// Date date = bussCommonBS.getBussDate();
// System.out.println(date);

}
}
