如何从Java EE Web应用程序访问属性文件？

问题描述

我已经在Eclipse中创建了一个动态Web项目。我在src目录下创建了一个属性文件：

 < project-root> /src/props.properties 
  

我在调试模式下通过Eclipse启动Tomcat。现在我想从我的一个POJO中读取属性文件，但是我收到一个FileNotFoundException。目前的路径似乎是Eclipse的路径。

我看了一下网络的解决方案，但没有一个为我工作。也许我做错了。代码如下：

 文件文件=新文件（props.properties）; 
 FileReader reader = new FileReader（file）; 
 properties.load（reader）; 
  

我应该如何访问属性文件？
你应该在哪里找到？

提前感谢

如果它是一个Web应用程序，那么属性将被部署到WEB-INF / classes，并且可以使用类加载器加载

  InputStream in = {NameOfClassWhereThisisInvoked} .class.getResourceAsStream（/ props.properties）; 
 properties.load（in）; 
 in.close（）; 
  

Actully应该工作，无论是否是webapp。

我假定src被定义为源文件夹

I have created a dynamic web project within Eclipse. I created a properties file inside the src directory:

<project-root>/src/props.properties

I'm starting Tomcat via Eclipse in debug mode. Now I want to read the properties file from one of my POJOs, but I get a FileNotFoundException. The current path seems to be the Eclipse path.

I had a look into the web for solution, but none of them worked for me. Maybe I did something wrong. The code is like this:

File file = new File("props.properties");
FileReader reader = new FileReader(file);
properties.load(reader);

How should I acces the properties file?Where should it be located?

Thanks in advance.

解决方案

If its a web application then the properties will get deployed to WEB-INF/classes and can be loaded using the class loader

InputStream in = {NameOfClassWhereThisisInvoked}.class.getResourceAsStream("/props.properties");
properties.load(in);
in.close();

Actully that should work regardless of whether it is a webapp or not.

I'm assuming src is defined as a source folder
