我试图在 Spring Boot 中使用 @Value 从我的 application.properties 中获取一个值，但无论我做什么，它始终为 null。
我在我的 HTTPClient 测试类中这样做。我已经尝试使用环境变量、propertySource、PostConstruct、使用 getter 和 setter 以及我可以在网上找到的任何其他东西，但它似乎根本没有填充……我的测试类在 src/test/java 和应用程序中。属性在 src/test/resources 中。我的 src/main/java 中也有一个 application.properties，但它位于一个完全不同的文件夹中，因此它不应该影响它。
这是我的代码:

assertEquals(resultJsonObj.containsKey("CoinsuranceAmount"), true);

我正在从我的 application.properties 中获取值以获取 IP 地址和端口并测试我的 Request.post。
这是我的 application.properties
server.port=9119
server.ssl.enabled=false
logging.config=classpath:logback-spring.xml
logging.file=messages
logging.file.max-size=50MB
logging.level.com.nulogix=DEBUG
billing.engine.address=127.0.0.1
billing.engine.port=9119
billing.engine.api.version=0.97
billing.engine.core.name=Patient_Responsibility
最佳答案
所以解决我的问题的方法是将 application.properties 从我的 main 复制到我的测试/资源。然后我使用 @PropertySource 将值更改为 test.properties，将其与 main 中的 application.properties 分开。我在我的端点配置中创建了一个值 bean，然后将它自动连接到我的 httpclient 测试类中。
我还在我的 SpringBootTest 注释中添加了 Web 环境，以使用 test.properties 中定义的端口并使用我的端点配置类和主应用程序类运行测试。这导致 @value 字符串被填充而不是 null。

关于java - Spring Boot @Value 没有被填充..为什么？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57454530/
