无法初始化类 org.apache.logging.log4j.core.LoggerContex

Question

由于最近在 Log4j 上发现了漏洞，我们的任务是迁移到版本 >= 2.16.0。最初，我的项目使用的是<version>1.2.17</version>

添加必要的依赖项并进行必要的更改后，在启动请求时出现以下错误：

引起原因：java.lang.NoClassDefFoundError：无法初始化类org.apache.logging.log4j.core.LoggerContext

和我的代码和 Log4J2 初始化

@Stateless
public class SessionKeyService {

    private static final Logger LOGGER = LogManager.getLogger(SessionKeyService.class);

    public String getSessionKeyID() {
        try {
            String url = properties.getProperty(Global.ENDPOINT_URL);

            ........

            SessionKey sessionKey = new SessionKey();
            sessionKey.setStatus(tokenObj.optString("Status"));
            sessionKey.setMessage(tokenObj.optString("Message"));
            sessionKey.setKey(tokenObj.optString("SessionKey"));

            return sessionKey.getKey();

        } catch (Exception ex) {
            LOGGER.error("Error: "+ex);
        }

        return null;
    }

拜托，我不知道 LoggerContext 会出现在哪里。

Answer 1

我发现尝试部署时 WildFly（WidlFly 版本 24）日志记录与应用程序冲突。

解决方案： 我jboss-deployment-structure.xml在我的中创建了一个/resources/webapp/WEB-INF/并包含以下内容

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <deployment>

        <exclude-subsystems>
            <subsystem name="logging"/>
        </exclude-subsystems>

    </deployment>
</jboss-deployment-structure>
