另外,如果将一个prototype-bean注入到一个singleton-bean中,那么每次从容器中获取的singleton-bean对应prototype-bean都是同一个,因为依赖注入仅会进行一次。 Request && Session && Application && WebSocket Scopes request和session这两个你也许有所耳闻,但是application和websocket是什么鬼?竟然还有这样的神仙scope??莫方...
When a managed bean is initialized by CDI the bean will be initialized in a very specific scope. The scope in which the bean is initialized will determine its lifecycle. CDI provides the following bean scopes: Update: Java EE 7 introduced a new set of CDI bean scopes, namely the Transactio...
基于Java的配置 具体实现代码我就不多说了,因为比较简单,无需列举。 Bean Scopes(Bean的执行范围) 定义时,可以选择声明该bean的作用域,最经常用的就是单例模式、多例模式 原型模式:要强制Spring每次需要一个新的bean实例时,应将bean的scope属性声明为prototype。
<beanid="beanId"class="com.howtodoinjava.BeanClass"scope="websocket"/> 6. Conclusion Spring framework has provided 6 built-in bean scopes, and instances can have different lifecycle spans within each scope. As a developer, we must choose the scope of any container-managed bean wisely. Also...
