org.springframework.beans.factory.BeanCreationException:

Error creating bean with name 'businessBean' defined in file [d:/workspace/TestSpring/bean.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'businessTarget' is defined

是什么原因？bean的路径我也查过了！

测试类：

ApplicationContext ac = new FileSystemXmlApplicationContext("bean.xml");
        BusinessInterface businessBean = (BusinessInterface) ac
                .getBean("businessBean");
        businessBean.hello();
