IDEA 使用java读取配置文件的方式

IDEA

项目机构如图：

测试代码：

public class TestUtil {

    public static void main(String[] args) {
        Properties properties = new Properties();
        InputStream resourceAsStream = TestUtil.class.getResourceAsStream("/showtime.properties");
        try {
            properties.load(resourceAsStream);
            System.out.println(properties.getProperty("redis.ip"));
        } catch (IOException e) {
            e.printStackTrace();
        }

        System.out.println("========");

        InputStream inputStream = TestUtil.class.getClassLoader().getResourceAsStream("showtime.properties");
        try {
            properties.load(inputStream);
            System.out.println(properties.getProperty("redis.ip"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

运行结果：
