本文整理了Java中org.apache.tika.Tika.parseToString()方法的一些代码示例，展示了Tika.parseToString()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。Tika.parseToString()方法的具体详情如下：
包路径：org.apache.tika.Tika
类名称：Tika
方法名：parseToString

Tika.parseToString介绍

[英]Parses the given file and returns the extracted text content.

To avoid unpredictable excess memory use, the returned string contains only up to #getMaxStringLength() first characters extracted from the input document. Use the #setMaxStringLength(int)method to adjust this limitation.
[中]解析给定文件并返回提取的文本内容。
为了避免不可预测的内存过量使用，返回的字符串最多只包含从输入文档中提取的#getMaxStringLength（）第一个字符。使用#setMaxStringLength（int）方法调整此限制。
