绑定@Autowired不工作内部实例启动与'新' [英] Binding with @Autowired not working inside instances initiated with 'new'

问题描述

在我的web spring应用程序中，我创建了一个关键字 new 的实例，如下所示。

在我的一个action类中，存在以下方法。

In my web spring application I create an instance with key word new as following.
In my one of action class, following method exists.

    public void process(){  

    MyBean b=new MyBean();//initiated the instance with new  
    b.process();


    }   

其他MyBean类

    @Service
    public class MyBean{  

    @Autowired  
    MyService service;  

    public void process(){ 

    service.execute(); // this service instance has not initialized by Spring DI :( .service object is null. 

    }
}

MyService实例不是通过spring依赖注入来设置的，是因为我自己创建了MyBean的实例，其中新的不春天？

the MyService instance is not set by spring Dependancy injection. Is it because that I create the instance of MyBean myself with new not the Spring ?

推荐答案

如果你想以编程方式自动连线，可以使用：

If you want to autowire programmatically, you can use:

private @Autowired AutowireCapableBeanFactory beanFactory;

public void process() {
   MyBean obj = new MyBean();
   beanFactory.autowireBean(obj);
   // obj will now have its dependencies autowired.
}
