session是有状态J2EEWeb应用程序作用域的核心和灵魂。
Session is the heart and soul of stateful J2EE Web application scopes.
CDI包含一个cdi容器服务，该服务根据应用程序作用域声明自动管理作用域；容器根据需要创建和销毁CDIbean。
CDI includes a CDI container service that manages scope automatically depending on the application scope declaration; CDI beans are created and destroyed on demand by the container.
作用域确定阶段的最后部分是一步一步地迁移应用程序的单个“垂直部分”。
The final part of a scoping exercise steps through the migration of a single "vertical slice" of your application.
这些规则使作用域能够在广泛的设计模式和应用程序中使用，但是这种灵活性的代价是增加了复杂性。
The rules enable scopes to be used in a wide range of design patterns and applications, but such flexibility comes at the cost of complexity.
对会话作用域(即在一个会话中存储和维护的数据的上下文)的适当处理是有状态应用程序开发的关键。
Proper handling of session scope — that is, the context of the data being stored and maintained in a session — is key to stateful application development.
在复杂应用程序的代码中，应该有可能清晰地确定出与给定参数规范相关的作用域或环境。
In the code of a complex application, it should be possible to clearly identify the scope, or context, associated with any given parameter specification.
同样地，应用程序连接的作用域可能也很有限。
Likewise, the scope of application connectivity might be limited.
这些尺度有助于识别应用程序的作用域内或作用域外需要关注的问题所在。
These metrics assist in identifying problem areas requiring attention either within or outside the scope of the application.
将假定无环境限定符作为名称前缀的参数有全局作用域，并且指的是层次结构中的较高层(应用程序)。
A parameter whose name is not prefixed by a context qualifier would be assumed to have global scope and refer to the higher level in the hierarchy (Application).
先读取技巧涉及重构（或编写）应用程序逻辑和工作流，以便所有的处理和读取操作在事务作用域的外部首先发生。
The read-first technique involves refactoring (or writing) the application logic and workflow so that all processing and read operations occur first, outside of a transaction's scope.
在本月，您将学到每种作用域为j2ee中的有状态应用程序开发带来了哪些东西，以及每种作用域最适合于哪种会话管理场景。
This month, you'll learn what each of the scopes brings to stateful application development in J2EE, and where each one best fits in terms of the different session management scenarios.
ODR将以 “应用程序为作用域”把传入的HTTP请求路由到任何能够处理请求的目标服务器中。
The ODRs will route the incoming HTTP requests in an “application scoped” fashion to any target server capable of servicing the request.
定义服务的过程通常是在更大的作用域（应用程序框架的作用域）内完成的。
This process of defining services is normally accomplished within a larger scope -- that of the Application Framework.
应用程序响应和静态内容的有效生存期和作用域可能有所不同，与静态内容页相比，通常应用程序的生存期较短，作用域也较小。
The valid lifetime and scope of application responses and static content may differ, although applications typically have a shorter lifetime and smaller scope than static content pages.
RT应用程序的设计者通常会将作用域与指定任务关联在一起，以便有效调优。
Designers of RT applications typically associate scopes with specific tasks so they can be tuned effectively.
作为迁移工作的一部分(这对确定垂直部分的作用域来说最是如此)，应用程序的业务逻辑不应改变。
As part of a migration effort (and this is most certainly true for the scoping vertical slice), the business logic of the application should not change.
在Web应用程序中，作用域指的是一个对象可以多大程度地为一个应用程序的组件所使用。
In a Web application, scope refers to the degree to which an object is made available to an application's components.
所有bean都有application作用域，因此Spring会在启动应用程序时将他们全部实例化。
All beans have application scope, so Spring will instantiate them all during application startup.
作用域可以指定成任何名字，但在Web应用程序中提供“session”和“request”便于使用。
Scopes can be given any name, but "session" and "request" are provided out of the box for use in web applications.
术语作用域指的是被存储数据的上下文(即该数据的“作用域”)；对作用域的适当处理在有状态Web应用程序的设计中处于核心地位。
The term scope refers to the context of stored data (the data's "scope"); and the proper handling of scope is at the heart of stateful Web application design.
在J2EEWeb应用程序中，一共有4种会话作用域。
该应用程序展示了如何通过使用conversation作用域将有状态的行为引入到jsf托管的bean。
This application demonstrates how stateful behavior can be introduced to JSF managed beans through the use of the conversation scope.
该应用程序展示了如何通过使用conversation作用域将有状态的行为引入到jsf托管的bean。
This application demonstrates how stateful behavior can be introduced to JSF managed beans through the use of the conversation scope.
