Java:将多个属性文件作为一个加载 [英] Java: Load multiple properties files as one

问题描述

对不起，标题不清楚.

我要做的是彼此叠加"加载配置文件.

What I'm trying to do is load configuration files "on top of each other".

说我有配置#1:

config.property=Something Here

和配置2:

config.otherproperty=Other Thingy Here

然后Java应用程序将其加载为:

And the java app loads it as this:

config.property=Something Here

config.otherproperty=Other Thingy Here

好像都是一个文件.

我该怎么做?

推荐答案

我不清楚您真正需要什么.如果我对您的理解正确，则要将两个属性文件加载到单个Properties对象中.如果是这种情况，您要做的就是这样:

I am unclear as to what you really need. If I understood you correctly, you want to load two properties file into a single Properties object. If this is the case, the all you have to do is something like this:

PropsDemo demo = new PropsDemo();
String prop1 = "config1.properties";
String prop2 = "config2.properties";

Properties props = new Properties();
InputStream input1 = demo.getClass().getClassLoader().getResourceAsStream(prop1);
InputStream input2 = demo.getClass().getClassLoader().getResourceAsStream(prop2);
try
{
    props.load(input1);
    props.load(input2);
    System.out.println(props.toString());
}
catch (IOException e)
{
    System.out.println("Something went wrong!");
}

文件 config1.properties 包含:

The file config1.properties contains:

color=blue

文件 config2.properties 包含:

And the file config2.properties contains:

shape=circle

上面的输出片段:

{shape=circle, color=blue}
