JSR 330 javax.inject.Provider没有在@Autowired字段

Question

我正在使用Provider在for循环中创建原型bean（带有@Autowired字段）

但看起来，提供商在弹簧框架方面表现不佳

每当我尝试执行Provider get()方法时，都不会注入Spring Autowired Environment Bean

我怀疑在调用get()时，我们正在获取JSR330托管Bean而不是Spring Managed Bean

看一下片段

BeanClass.java

@Component
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class BeanClass implements Iface {
    @Autowired
    private Environment env;
    @Override
    public void doit() {
        System.out.println("hoo hoo "+env.getProperty("propkey"));
    }
}

Classy.java

@Component
public class Classy {
    @Autowired
    private Provider<Iface> ifaceProvider;
    public void doit_general() {
        for(int i=0;i<2;i++) {
            Iface if = ifaceProvider.get();
            if.doit();
        }
    }
}

当我执行此操作时，我收到错误，指出＆＃34; environment＆＃34; bean不可用

或者我应该在@Autowired中使用@Inject吗？我不太确定......

任何能够澄清这一点并提供解决方案的Spring Sensei？

更新

这很奇怪......当我创建一个虚拟代码并复制它时，环境已在@Autowired字段中正确注入...
