JNDI Context的意思|示意

In this section, you see how to develop a portlet application that accesses a session bean using JNDI context.

在本部分中，您将看到如何开发使用JNDI上下文访问会话bean的portlet应用程序。

Enable JPA access within an OSGi context, using JNDI to perform OSGi service registry lookup.

支持在OSGi背景下进行JPA访问，使用JNDI来执行osgi服务注册查找操作。

You can even store these jndi context properties in a properties file (the standard name is jndi.properties) and then modify them without having to change (and recompile and re-JAR) any code at all.

您甚至可以在属性文件里保存这些jndi上下文属性(标准名称为jndi . properties)。然后，不用再对代码做任何的变动就可以修改这些属性了。

The Spring context in the Blether WAR looks up the EntityManagerFactory that it USES from the web module's local JNDI, where it is mapped by a persistence-unit-ref in the module's web.xml file.

Blether WAR中的Spring上下文通过web模块的本地JNDI查询它使用的EntityManagerFactory，其中它由模块的web . xml文件中的一个persistence - unit - ref所映射。

The change to the Spring application context also adds a layer of laziness to the JNDI lookup by setting lookup-on-startup to false, which also requires the proxy-interface attribute to be specified.

对Spring应用程序上下文的更改还通过将lookup - on - startup设置为false添加延迟层到JNDI查询，这也需要指定proxy - interface属性。

The above configuration specifies the initial context factory as com.sun.jndi.fscontext.RefFSContextFactory and the provider URL as the file-based file:/C:/JNDI-Directory for JNDI lookup.

以上配置进行 JNDI 查询时用 com.sun.jndi.fscontext.RefFSContextFactory 指定初始上下文工厂，用基于文件的 file:/C:/JNDI-Directory 作为提供者 URL。
