•Spring IOC 容器可以自动装配 Bean. 需要做的仅仅是在 <bean> 的 autowire 属性里指定自动装配的模式 •byType(根据类型自动装配): 若 IOC 容器中有多个与目标 Bean 类型一致的 Bean. 在这种情况下, Spring 将无法判定哪个 Bean 最合适该属性, 所以不能执行自动装配. •byName(根据名称自动装配): 必须将目标 Bean 的名称和属性名设置的完全相同. •constructor(通过构造器自动装配): 当 Bean 中存在多…

在应用中一般普通的JavaPojo都是由Spring来管理的,所以使用autowire注解来进行注入不会产生问题,但是有两个东西是例外的,一个是 Filter,一个是Servlet,这两样东西都是由Servlet容器来维护管理的,所以如果想和其他的Bean一样使用Autowire来注入的 话,是需要做一些额外的功夫的.对于Filter,Spring提供了DelegatingFilterProxy,所以本文主要讲述Servlet的解决. servlet ,會碰到無法讀到 spring 定義的ann…
