是否可以在不使用ApplicationContextAware的情况下检索具有原型范围的Spring bean [英] Is it possible to retrieve a Spring bean with prototype scope without using ApplicationContextAware

问题描述

使用Spring 3.1。如果我想检索具有原型范围的bean（即每次都想要一个不同的类实例），是否可以在不必使用ApplicationContextaware类的情况下检索bean？

Using Spring 3.1. If I want to retrieve a bean with prototype scope (i.e. I want a different instance of the class each time), is it possible to retrieve the bean without having to use an ApplicationContextaware class?

这是我目前的操作方式

@Component
@Qualifier("MyService")
public class MyServiceImpl implements MyService {

    @Override
    public void doSomething() {
        Blah blah = (Blah)ApplicationContextProvider.getContext().getBean("blah");
        blah.setThing("thing");
        blah.doSomething();
    }
}


@Component("blah")
@Scope("prototype")
public class Blah {
    ....
}

其中ApplicationContextProvider实现了ApplicationContextAware。

where ApplicationContextProvider implements ApplicationContextAware.

是否可以通过注释或简单的Spring配置来执行此操作而不必使用ApplicationContextAware类？

Is it possible to do this with annotations or simple Spring configuration without having to use an ApplicationContextAware class?
