java - Maven 测试失败 - 属性 Autowiring 不起作用

Question

我有一个 Spring Boot 应用程序，“mvn 测试”失败，因为 Autowired 无法从 application.yml 文件中读取值。

类文件:

@Configuration
public class LogConfig {

    private SettingsRepository settingsRepository;

    @Value("${build.version}")
    private String buildVersion;

    @Value("${build.name}")
    private String buildName;

    public LogConfig(SettingsRepository settingsRepository) {
        this.settingsRepository = settingsRepository;
    }

    @Scheduled(fixedDelay = 5000)
    public void injectDataForLogging() throws SocketException {
        MDC.put("applicationToken", settingsRepository.getToken().isPresent() ? settingsRepository.getToken().get() : "NO-TOKEN");
        MDC.put("macAddressList", MACAddressUtil.getMACAddresses().toString());
        MDC.put("application", buildName);
        MDC.put("applicationVersion", buildVersion);
    }
}

application.yml:

build:
  version: @project.version@
  name: @project.artifactId@

pom.xml:

<artifactId>something</artifactId>
<version>2.0.0</version>

错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'logConfig': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'build.version' in value "${build.version}"

当我运行应用程序时，一切正常:/

就像将 pom.xml 属性传递到 main application.yml 一样，如下所示:

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>

您需要执行相同的操作才能将这些属性传递给您的测试资源:

 <build>
    <testResources>
       <testResource>
          <directory>src/test/resources</directory>
              <filtering>true</filtering>
          </testResource>
    </testResources>
 </build>
