本文整理了Java中org.camunda.bpm.engine.variable.Variables.fileValue()方法的一些代码示例，展示了Variables.fileValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Variables.fileValue()方法的具体详情如下：
包路径：org.camunda.bpm.engine.variable.Variables
类名称：Variables
方法名：fileValue

Variables.fileValue介绍

[英]Shortcut for calling Variables.fileValue(name).file(file).mimeType(type).create(). The name is set to the file name and the mime type is detected via MimetypesFileTypeMap.
[中]调用变量的快捷方式。文件值（名称）。文件。mimeType（类型）。创建（）。名称设置为文件名，mime类型通过MimetypesFileTypeMap检测。
