在哪里放置属性文件？

Question

I tried to read a .properties file and have code as following:

public final class Config  {
  static {
    Properties properties = new Properties();
    InputStream propertiesStream = Object.class.getResourceAsStream("config.properties");

    if (propertiesStream != null) {
      try {
        properties.load(propertiesStream);
      } catch (IOException e) {
        e.printStackTrace();
      }
    } else {
      System.out.println("file not found");
    }
  }
}

but it keeps saying file not found.

The content of properties is

pwd=passw0rd

Anyone knows how to solve this problem?

Answer 1

它应该在classpath中，把它放到你的根源包中，如果它的maven项目把它放到src/main/resources目录中

Answer 2

it should be in WebContent/Web-Inf/ folder

and in you xml file define the bean like this :

<bean id="propertyConfigurer" class="com.your.project.util.properties.ApplicationProperties">
    <property name="locations">
        <list>
            <value>/WEB-INF/application.properties</value>
        </list>
    </property>
</bean>

Answer 3

You could also keep config.properties in the same folder as Config.java.

//InputStream propertiesStream = Object.class.getResourceAsStream("config.properties");
InputStream propertiesStream   = Config.class.getResourceAsStream("config.properties");

Answer 4

You can have two choices of selecting the path,

1. Open the file containing folder and get the path and save that path in the string with file like,

   InputStream propertiesStream = Object.class.getResourceAsStream(path + File.seperator + "config.properties");

2. Save the file in src path,

   WorkSpace -> Project Name -> Copyhere
