首先,我们需要创建一个txt文件,并通过输出流将文字内容写入文件中。在Java中,可以使用File类和FileOutputStream类来实现。 importjava.io.File;importjava.io.FileOutputStream;importjava.io.IOException;publicclassTextToFile{publicstaticvoidmain(String[]args){// 创建文件对象Filefile=newFile("output.txt");try...
File file = new File(fileentity.getStoreaddress(), uuid); if(file.exists()) { FileInputStream fis; try { fis = new FileInputStream(file); response.setContentType("application/x-msdownload"); response.addHeader("Content-Disposition", "attachment; filename=" + filename ); ServletOutputStre...

在Spring Framework里的spring-core核心包里面,有个org.springframework.util里面有不少非常实用的工具类。 该工具包里面的工具类虽然是被定义在Spring下面的,但是由于Spring框架目前几乎成了JavaEE实际的标准了,因此我们直接使用也是无妨的,很多时候能够大大的提高我们的生产力。本文主要介绍一些个人认为还非常实用的工具...
