java - 使用 Spring xml 配置从 Rest 端点获取 Maven 构建信息

Question

目前我有一个很好的工作解决方案:

来 self 的 pom.xml:

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

资源/mvn.build.properties:

version=${pom.version}
build.timestamp=${timestamp}

BuildInfoProviderImpl.java:

@Service
@PropertySource("classpath:mvn.build.properties")
public class BuildInfoProviderImpl implements BuildInfoProvider {

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

    private BuildInfo buildInfo;

    @Override
    public BuildInfo getBuildInfo() {
         return buildInfo;
    }

    @PostConstruct
    public void activate() {
        buildInfo = new BuildInfo(
                LocalDateTime.parse(dateTime, Constants.DATE_TIME_FORMATTER),
                version);
    }
}

HealthEndpoint.java:

@Service
@Path("_health")
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public class HealthEndpoint {

    private static final Logger LOGGER = LoggerFactory.getLogger(
        HealthEndpoint.class);

    private BuildInfoProvider buildInfoProvider;

    public HealthEndpoint(BuildInfoProvider buildInfoProvider) {
        this.buildInfoProvider = buildInfoProvider;
    }

    @GET
    public BuildInfo getBuildInfo() {
        LOGGER.debug("Build info has been requested");
        return buildInfoProvider.getBuildInfo();
    }
}

问题是:如何使用 xml 配置文件配置完全相同的东西？

我尝试使用 maven-war-plugin 添加属性，然后从我的服务中获取它，但这根本不起作用。在类路径中看不到它。仅供引用:它在 ${baseFolder}/target/{app}.war 下生成。

我需要这样的东西，但不知何故我必须设置maven构建属性，我尝试的一切都失败了:

<bean id="buildInfoProvider" class="service.impl.BuildInfoProviderImpl"/>

<bean id="healthEndpoint" class="endpoint.HealthEndpoint">
    <constructor-arg ref="buildInfoProvider"/>
</bean>

好吧，由于我实际上没有正确的答案，所以我自己提供:

public class HealthEndpoint {

  private static final Logger LOGGER = LoggerFactory.getLogger(HealthEndpoint.class);

  @Context
  private ServletContext context;

  private BuildInfo buildInfo;

  @GET
  public BuildInfo getBuildInfo() {
    LOGGER.debug("Build info has been requested");
    setBuildInfo();
    return buildInfo;
  }

  private void setBuildInfo() {
    if (buildInfo != null) {
        return;
    }
    // some logic of setting build info with help of manifest file here
  }
}

在我的 xml 配置中，我只是创建这个 bean，如下所示:

<bean id="healthEndpoint" class="endpoint.HealthEndpoint"/>
