Struts 2 bean配置默认范围 [英] Struts 2 bean configuration default scope

问题描述

我正在尝试使用配置文件使用Struts2的基本DI，如这里所述。

I'm trying to use basic DI with Struts2 using the configuration file as described here.

但是，我无法找到注入bean的默认范围。

However, I was not able to find what the default scope is for injecting a bean.

我知道Spring的默认范围是Singleton，但我不想假设与Struts2相同。

I know that the default scope is Singleton for Spring but I didn't want to assume the same with Struts2.

任何想法？

推荐答案

默认范围是 singleton ，但是有一个名称为的范围默认哪个不同。可以通过这个问题让您更好地了解Struts2中的范围。框架支持范围，如 singleton ，默认和线程你应该手动实现的其他范围。

The default scope is singleton, but there's a scope with name default which is different. May be this question let you better understand scopes in Struts2. The framework support scopes like singleton, default, and thread other scopes you should implement manually.

查看源代码，其中定义了范围。

Look at the source code where the scopes are defined.

澄清名为的范围，默认表示每次注入一个实例。您可以在评论中找到 Scope.DEFAULT 。

To clarify the scope named default means a one instance per injection. You can find this in comments to Scope.DEFAULT.
