Question

尝试从页面使用示例XML文件“Sample 1 / Log4j 2 XML configuration”：

http://logging.apache.org/log4j/2.x/manual/migration.html

但它给出了：

2013-09-25 02:22:59,182 ERROR Root contains an invalid element or attribute "AppenderRef"

有什么想法吗？

我在pom.xml中使用这种依赖，

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.0-beta8</version>
</dependency>

我在课堂上使用它：

private static final Logger logger = LogManager.getLogger(App.class.getName());

我按如下方式指定配置文件：

java -Dlog4j.configurationFile=log4j2.xml -jar target/project-jar-with-dependencies.jar

Answer 1

这是2.0-beta8的错误，它不存在于2.0-beta9

以下是使用beta9的输出

        LOG.debug("Log4j Impl test started...");
        LOG.warn("  Log4j Impl test warn...");
        LOG.info("  Log4j Impl test info...");
        LOG.error("  Log4j Impl test error...");
...

以下是使用beta8的输出：

2013-09-24 16:39:28,233 ERROR Root contains an invalid element or attribute "AppenderRef"

log4j2 - Root包含无效的元素或属性
