Maven配置文件-如何在.properties文件中获取分配给属性的值,并将其分配给班级中的变量?

问题描述

在这里真的需要一些帮助,因为我似乎无法弄清楚。

我已遵循以下指南https://mkyong.com/maven/maven-profiles-example/

中的 Maven个人资料–示例2

这是我的pom.xml文件

这是我的属性文件。在“测试”和“集成”时,我仅使用两个环境配置

这是我的BaseTest类。以前,我直接从pom.xml文件获取URL值,并将它们分配给变量以供测试使用。现在如何访问配置文件中存储的值,以便将它们分配给变量以供测试使用?

enter image description here

调试时,我得到的都是空值。在终端中运行'mvn软件包-P集成'也不起作用

enter image description here

但是,它确实表示我在执行“ mvn软件包-P集成”时指定的配置文件处于活动状态

enter image description here

总而言之,我要实现的目标是访问存储在配置文件中的值,以便可以将其分配给变量以供测试使用。也许我误会了它。我对Maven和Java还是陌生的,将不胜感激

谢谢

解决方法

System.getProperty不用于从用户定义的文件中检索值。您需要手动加载属性,如下所示:

public class BaseTest {

    String BaseUrl;

    public BaseTest() {
        Properties prop = new Properties();
        try (InputStream resourceAsStream = getClass().getClassLoader().getResourceAsStream("config.properties")) {
            prop.load(resourceAsStream);
            BaseUrl = (String) prop.get("url.baseUrl");
            
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
,

请参阅 How to read data from java properties file using Spring Boot

您编写的代码只能从环境变量中读取值。
