本文整理了Java中java.sql.Blob.free()方法的一些代码示例，展示了Blob.free()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。Blob.free()方法的具体详情如下：
包路径：java.sql.Blob
类名称：Blob
方法名：free

Blob.free介绍

[英]Frees any resources held by this blob. After free is called, calling method other than free will throw SQLException (calling freerepeatedly will do nothing).
[中]释放此blob所持有的任何资源。调用free后，调用free以外的方法将抛出SQLException（重复调用free将不起任何作用）。
