通过资源读写Java文件 [英] Read and Write to Java file via Resource

问题描述

我正在尝试读取和写入文件，但我想通过资源访问该文件.

I'm trying to read and write to a file but I'd like to access that file via Resource.

这就是我所做的

File f = new File(ClassLoader.getSystemResource("/blah/blah/Properties.prop").toURI());
BufferedReader br = new BufferedReader(new FileReader(f));
String line = br.readLine();

PrintWriter p = new PrintWriter(new File(ClassLoader.getSystemResource("/blah/blah/Properties.prop").toURI()));

但似乎都不正确.这样做的正确方法是什么?

but neither seems correct. What is the correct way to do this?

推荐答案

对于输入，请尝试以下操作:

For input, try below:

     InputStreamReader isReader = 
                      new InputStreamReader(
                          this.getClass().getResourceAsStream(templateName));
      BufferedReader br = new BufferedReader(isReader);     

或

     InputStreamReader isReader = 
                      new InputStreamReader(
                          <youclassName>.class.getResourceAsStream(templateName));
      BufferedReader br = new BufferedReader(isReader);   

对于输出，请尝试以下操作:

For output, try below:

      PrintWriter writer = 
               new PrintWriter(
                     new File(this.getClass().getResource(templateName).getPath()));
