是什么在Spring框架@Inject和@Autowired之间的区别？哪一个是什么情况下使用？ [英] What is the difference between @Inject and @Autowired in Spring Framework? Which one to use under what condition?

问题描述

我要通过SpringSource的，并在博客作者之一，一些博客中使用 @Inject ，我想他也可以用 @Autowired

I am going through some blogs on SpringSource and in one of the blog author is using @Inject and I suppose he can also use @Autowired

下面是一块code的：

Here is the piece of code:

@注入私人CustomerOrderService customerOrderService;

我不知道关于 @Inject 和 @Autowired ，并将AP preciate如果之间的区别有人可以解释这种差异，哪一个什么情况下使用？

I am not sure about the difference between @Inject and @Autowired and would appreciate if someone can explain the difference and which one to use under what situation?

推荐答案

这里假设你指的是<一个href=\"http://download.oracle.com/javaee/6/api/javax/inject/Inject.html\"><$c$c>javax.inject.Inject注释。 @Inject 是Java CDI的一部分（ Java EE 6中（JSR-299）引入上下文和依赖注入）标准，阅读更多信息。春天已经选择使用支持 @Inject 同义词用自己的 @Autowired 注释。

Assuming here you're referring to the javax.inject.Inject annotations. @Inject is part of the Java CDI (Contexts and Dependency Injection) standard introduced in Java EE 6 (JSR-299), read more. Spring has chosen to support using @Inject synonymously with their own @Autowired annotation.

因此​​，要回答你的问题， @Autowired 是Spring自己的（传统）注释。 @Inject 是一个新的Java技术，名为CDI，定义了类似的春天依赖注入一个标准的组成部分。在Spring应用程序，这两个注释的工作原理春天已经决定支持除一些JSR-299注解自己以同样的方式。

So, to answer your question, @Autowired is Spring's own (legacy) annotation. @Inject is part of a new Java technology called CDI that defines a standard for dependency injection similar to Spring. In a Spring application, the two annotations works the same way as Spring has decided to support some JSR-299 annotations in addition to their own.
