Java Spring Boot@Value未填充..为什么?
我正在尝试使用@value从Spring Boot中的application.properties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。我尝试过使用环境变量、propertySource、PostConstruct、getter和setter,以及我在网上能找到的任何东西,但它似乎一点也没有普及。。。我的测试类在src/test/java中,application.properties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,因此不应该影响它 这是我的密码:Java Spring Boot@Value未填充..为什么?,java,spring-boot,testing,properties,null,Java,Spring Boot,Testing,Properties,Null,我正在尝试使用@value从Spring Boot中的application.properties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。我尝试过使用环境变量、propertySource、PostConstruct、getter和setter,以及我在网上能找到的任何东西,但它似乎一点也没有普及。。。我的测试类在src/test/java中,application.properties在src/test/resources中。我的src/mai

您需要将application.properties移动到
src/test/resource
文件夹。对于测试,弹簧从该路径加载应用程序属性。您需要将application.properties移动到src/test/resource
文件夹。对于测试,请从此路径选择弹簧载荷应用程序属性。您可以执行以下操作:
@RunWith(SpringRunner.class)
@SpringBootTest(classes={Application.class})
public class HttpClientTest {
.............
.................
}
您可以执行以下操作:
@RunWith(SpringRunner.class)
@SpringBootTest(classes={Application.class})
public class HttpClientTest {
.............
.................
}
因此,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。我在端点配置中创建了一个值bean,然后将其自动连接到httpclient测试类中 我还在SpringBootTest注释中添加了web环境,以使用test.properties中定义的端口,并使用端点配置类和主应用程序类运行测试。这导致@value字符串被填充且不为null
