Properties JBoss AS 7特定于应用程序的属性文件

我有几个独立的javaee模块（warweb应用程序和jarejb模块），我将它们部署在jboss7.1.1as上。 我想：

将这些模块的配置集中在一个*.properties文件中

使此文件在类路径中可用

使此文件的安装/配置尽可能简单。理想情况下，只需将其放在某个JBoss文件夹中，如：${JBoss_HOME}/standalone/configuration

无需重新启动应用程序服务器即可对此文件进行更改

这可能吗

我已经找到了这个链接：，它解释了更好的方法是创建静态JBoss模块。但是，在我部署的每个应用程序模块中，我都必须依赖于这个静态模块，这是我试图避免的一种耦合。

也许一个简单的解决方案是从单例或静态类读取文件

private static final String CONFIG_DIR_PROPERTY = "jboss.server.config.dir"; 

private static final String PROPERTIES_FILE = "application-xxx.properties";

private static final Properties PROPERTIES = new Properties();

static {
    String path = System.getProperty(CONFIG_DIR_PROPERTY) + File.separator + PROPERTIES_FILE;  
    try {  
        PROPERTIES.load(new FileInputStream(path));
    } catch (MalformedURLException e) {
       //TODO 
    } catch (IOException e) {
       //TODO
    } 
}

下面是一个仅使用CDI的完整示例，摘自本文

这种配置也适用于JBossAS7

在WildFly配置文件夹中创建并填充属性文件

$ echo 'docs.dir=/var/documents' >> .standalone/configuration/application.properties

将系统属性添加到WildFly配置文件

$ ./bin/jboss-cli.sh --connect
[standalone@localhost:9990 /] /system-property=application.properties:add(value=${jboss.server.config.dir}/application.properties)

这将向服务器配置文件（standalone.xml或domain.xml）添加以下内容：

创建生产者方法；这将生成要注入的对象

import javax.enterprise.inject.Produces;
import javax.enterprise.inject.spi.InjectionPoint;
import javax.inject.Inject;

public class ApplicationPropertyProducer {

    @Inject
    private PropertyFileResolver fileResolver;

    @Produces
    @ApplicationProperty(name = "")
    public String getPropertyAsString(InjectionPoint injectionPoint) {

        String propertyName = injectionPoint.getAnnotated().getAnnotation(ApplicationProperty.class).name();
        String value = fileResolver.getProperty(propertyName);

        if (value == null || propertyName.trim().length() == 0) {
            throw new IllegalArgumentException("No property found with name " + value);
        }
        return value;
    }

    @Produces
    @ApplicationProperty(name="")
    public Integer getPropertyAsInteger(InjectionPoint injectionPoint) {

        String value = getPropertyAsString(injectionPoint);
        return value == null ? null : Integer.valueOf(value);
    }
}

最后，将属性注入一个CDIBean

import javax.ejb.Stateless;
import javax.inject.Inject;

@Stateless
public class MySimpleEJB {

    @Inject
    @ApplicationProperty(name = "docs.dir")
    private String myProperty;

    public String getProperty() {
        return myProperty;
    }
}

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

import javax.inject.Qualifier;

@Qualifier
@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.METHOD, ElementType.FIELD, ElementType.CONSTRUCTOR })
public @interface ApplicationProperty {

    // no default meaning a value is mandatory
    @Nonbinding
    String name();
}

import javax.enterprise.inject.Produces;
import javax.enterprise.inject.spi.InjectionPoint;
import javax.inject.Inject;

public class ApplicationPropertyProducer {

    @Inject
    private PropertyFileResolver fileResolver;

    @Produces
    @ApplicationProperty(name = "")
    public String getPropertyAsString(InjectionPoint injectionPoint) {

        String propertyName = injectionPoint.getAnnotated().getAnnotation(ApplicationProperty.class).name();
        String value = fileResolver.getProperty(propertyName);

        if (value == null || propertyName.trim().length() == 0) {
            throw new IllegalArgumentException("No property found with name " + value);
        }
        return value;
    }

    @Produces
    @ApplicationProperty(name="")
    public Integer getPropertyAsInteger(InjectionPoint injectionPoint) {

        String value = getPropertyAsString(injectionPoint);
        return value == null ? null : Integer.valueOf(value);
    }
}

import javax.ejb.Stateless;
import javax.inject.Inject;

@Stateless
public class MySimpleEJB {

    @Inject
    @ApplicationProperty(name = "docs.dir")
    private String myProperty;

    public String getProperty() {
        return myProperty;
    }
}
