Spring 注入失败的原因
有一次写代码如下
??ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
??HarborBusiness service = (HarborBusiness) ctx.getBean("harborBusiness");
?
总是报no bean named
?
查了半天没查出来了，后来把前一个版本的工程拿来，一点一点的加功能
终于发现了，根本和工程没有一点关系，是 ctx.getBean("harborBusiness"); 这里写错了，
HarborBusiness它本身是个接口类，而以前的测试都是? ctx.getBean("harborBusinessImpl");这样的
HarborBusinessImpl这个才是真正的实现类，spring的注入的语法也是在这个类里写的
?
晕了。。。呵。。。
