Spring 当未在命令行指定配置文件时，启动集成测试无法获取默认配置文件并抛出错误

Question

我正在尝试运行基于 Spring Boot 配置文件的 Selenium 测试。我已经在我的 pom 中设置了默认配置文件，但测试没有发现它。

不确定我是否缺少任何配置。

命令（执行测试）：

mvn 测试 -Dspring.profiles.active=google - 工作正常
mvn 测试 -Dspring.profiles.active=saucelabs - 工作正常
mvn 测试 - 错误（如下所示）

错误

您需要启用资源过滤

<build>
    <resources>
        <resource>
            <directory>src/test/resources/</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Answer 2

如果您没有指定任何配置文件，spring 将激活默认配置文件。对于默认配置文件，它会扫描 application.properties 文件以获取配置值。因此，您需要执行以下操作：

创建application.properties 文件
添加base.url=<url for default profile>

之后，它应该可以正常工作。

Spring 当未在命令行指定配置文件时，启动集成测试无法获取默认配置文件并抛出错误
