Question

我想做什么？
- 为了进行测试，我想为我的应用程序设置serverKey和validity，并希望将货物注入TokenUtils，因此在加载应用程序时可以使用这些值

我尝试了什么？
我使用JBoss作为Container，相关代码是

@Stateless
public class TokenUtils {

    public static final String AUTH_TOKEN = "X-BB-AUTH";
    public static final String BB_AUTH_PRIVATE_KEY = "auth.key";
    public static final String BB_AUTH_VALIDITY = "auth.validity";
    private static final Pattern PATTERN = Pattern.compile(":");

    private String serverPrivateKey;
    private long validity;

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

    @SuppressWarnings("UnusedDeclaration")
    public TokenUtils() {
    }

    public TokenUtils(@Nonnull @Configuration(BB_AUTH_PRIVATE_KEY) final String serverPrivateKey,
                      @Configuration(BB_AUTH_VALIDITY) final long validity) {
        this.serverPrivateKey = serverPrivateKey;
        this.validity = validity;

        LOGGER.info("serverPrivateKey:" + serverPrivateKey);
        LOGGER.info("validity:" + validity);
    }
}

另外，我在创建META-INF/beans.xml的同一个包的src/main/resources中有TokenUtils，所以bean实例化不是问题我想

我希望在货物实例化bean时注入值，因此我将pom.xml中的值设置为

<container>
  <systemProperties>
    <auth.key>secure</auth.key>
    <auth.validity>720000</auth.validity>
  </systemProperties>
</container>

当我开始装货时，我发现以下情况发生了

INFO] [talledLocalContainer] 06:07:08,068 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-1) JNDI bindings for session bean named TokenUtils in deployment unit deployment "market.war" are as follows:
[INFO] [talledLocalContainer] 
[INFO] [talledLocalContainer]   java:global/market/TokenUtils!com.org.proj.service.authentication.TokenUtils

[INFO] [talledLocalContainer]   java:global/market/TokenUtils
[INFO] [talledLocalContainer]   java:app/market/TokenUtils
[INFO] [talledLocalContainer]   java:module/TokenUtils

问题吗
- 但值为serverPrivateKey=null和validity=0
- 此外，在bean实例化期间，我应该能够看到LOGGER.info值，但我在日志中找不到它们

我做错了什么？

我意识到了这个错误。我没有在@Inject构造函数中使用TokenUtils。以下更改修复了它

@Inject
public TokenUtils(@Nonnull @Configuration(BB_AUTH_PRIVATE_KEY) final String serverPrivateKey,
                      @Configuration(BB_AUTH_VALIDITY) final long validity) {
        this.serverPrivateKey = serverPrivateKey;
        this.validity = validity;

        LOGGER.info("serverPrivateKey:" + serverPrivateKey);
        LOGGER.info("validity:" + validity);
    }

我可以在日志中看到以下值

[INFO] [talledLocalContainer] 06:39:30,042 INFO  [com.org.proj.commons.cdi.config.ConfigurationProvider] (http--0.0.0.0-9090-1) getProperty(auth.key) is secure
[INFO] [talledLocalContainer] 06:39:30,043 INFO  [com.org.proj.commons.cdi.config.ConfigurationProvider] (http--0.0.0.0-9090-1) getProperty(auth.validity) is 720000

在Bean注入期间，Cargo无法设置系统属性值
