如何在Eclipse中的Java项目中添加Java Properties文件

Question

I was using Unix before to compile and edit my Java. In that I have used property files right inside my current working directory where the class file exists. Now i have switched to Eclipse IDE. I dont know how to add the same properties file here in Eclipse. Please help me.

Answer 1

1. Create Folder “resources” under Java Resources folder if your project doesn't have it.
   2. create config.properties file with below value.

/Java Resources/resources/config.properties

for loading properties.

Properties prop = new Properties();
InputStream input = null;

try {

      input = getClass().getClassLoader().getResourceAsStream("config.properties");


    // load a properties file
    prop.load(input);

    // get the property value and print it out
    System.out.println(prop.getProperty("database"));
    System.out.println(prop.getProperty("dbuser"));
    System.out.println(prop.getProperty("dbpassword"));

} catch (IOException ex) {
    ex.printStackTrace();
} finally {
    if (input != null) {
        try {
            input.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Answer 2

在包资源管理器中，右键单击该包并选择New - > File，然后输入包含“.properties”后缀的文件名。

Answer 3

It should work ok as it is in Unix, if you have properties file in current working directory. Another option would be adding your properties file to the classpath and getting the inputstream using this.getClass().getClassLoader().getResourceAsStream("xxxxx.properties"); More here

steps:

1. Right click on any package where you want to create your .properties file or create a new package as required
2. now select new then select file (if you dont find file then go to location of your package and create it there)
3. now named it as yourfilename.properties

Answer 5

If you have created a Java Project in eclipse by using the 'from existing source' option then it should work as it did before. To be more precise File > New Java Project . In the Contents section select ' Create project from existing source ' and then select your existing project folder. The wizard will take care of the rest.

Answer 6

1. Right click on the folder within your project in eclipse where you want to create property file
2. New->Other->in the search filter type file and in the consecutive window give the name of the file with .properties extension

Answer 7

To create a property class please select your package where you wants to create your property file.

Right click on the package and select other. Now select File and type your file name with (.properties) suffix. For example: db.properties. Than click finish. Now you can write your code inside this property file.

Answer 8

If you are working with core java, create your file(. properties ) by right clicking your project. If the file is present inside your package or src folder it will throw an file not found error
