wildfly：从配置目录中读取属性 [英] wildfly: reading properties from configuration directory

问题描述

我正在尝试从wildfly配置文件夹中的属性文件中读取部署特定信息。我试过这个：

I'm trying to read deployment specific information from a properties file in my wildfly configuration folder. I tried this:

@Singleton
@Startup
public class DeploymentConfiguration {

  protected Properties props;

  @PostConstruct
  public void readConfig() {

    props = new Properties();
    try {
      props.load(getClass().getClassLoader().getResourceAsStream("my.properties"));
    } catch (IOException e) {
      // ... whatever
    }
  }

但显然这不起作用，因为配置文件夹不再在类路径中。现在我找不到一个简单的方法来做到这一点。我最喜欢的是这样的：

But apparently this is not working since the configuration folder is not in the classpath anymore. Now I can't find an easy way to do it. My favorite would be something like this:

@InjectProperties("my.properties")
protected Properties props;

到目前为止，我在网上找到的唯一解决方案是制作我自己的OSGi模块，但我相信那里必须是一种更简单的方法（一个没有OSGi！）。谁有人可以告诉我怎么做？

The only solution I found on the web so far involves making my own OSGi module, but I believe there must be an easier way to do it (one without OSGi!). Can anyone show me how?

推荐答案

如果你想从配置目录中显式读取文件（例如 $ WILDFLY_HOME / standalone / configuration 或 domain / configuration ）系统属性中包含路径。只需执行 System.getProperty（jboss.server.config.dir）; 并将您的文件名附加到该文件名即可获取该文件。

If you want to explicitly read a file from the configuration directory (e.g. $WILDFLY_HOME/standalone/configuration or domain/configuration) there's a system property with the path in it. Simply do System.getProperty("jboss.server.config.dir"); and append your file name to that to get the file.

你不会把它读作资源，所以...

You wouldn't read it as a resource though, so...

String fileName = System.getProperty("jboss.server.config.dir") + "/my.properties";
try(FileInputStream fis = new FileInputStream(fileName)) {
  properties.load(fis);
}

然后会为你加载文件。

此外，由于WildFly不再提供OSGi支持，我不知道如何创建OSGi模块可以帮助你。

Also, since WildFly doesn't ship with OSGi support anymore, I don't know how creating an OSGi module would help you here.
