log4j.属性被忽略

java intellij-idea maven-2 log4j wicket

2022-09-03 15:09:25

我有一个Java EE 6 Wicket应用程序，使用IntelliJ IDEA 9.0.3在glassfish v3.0.1上使用IntelliJ IDEA 9.0.3部署。我使用slf4j-log4j12-1.5.6和slf4j-api-1.5.8和log4j-1.2.16进行日志记录。

以前，当我通过netbeans或eclipse进行部署时，它工作正常，但是当我使用IntelliJ IDEA部署时，我的log4j.properties文件被忽略，glassfish的日志记录处理我的日志消息。我不认为IDEA与它有任何关系，其他一定发生了什么变化，我只是无法弄清楚是什么。

我已经验证了我的log4j.properties文件在我的WEB-INF/classes目录中，而slf4j/log4j jars在我的战争的WEB-INF/lib目录中。我是否缺少某种配置来使此功能正常工作？

谢谢。

编辑：更新了更多信息，发布了pom依赖项。

答案 1

更新：我试图重现问题。我创建了一个简单的 Wicket 项目（与你相同的版本）：

mvn archetype:create \
-DarchetypeGroupId=org.apache.wicket \
-DarchetypeArtifactId=wicket-archetype-quickstart \
-DarchetypeVersion=1.4.9 \
-DgroupId=com.mycompany \
-DartifactId=my-wicketapp

它有一个简单的log4j.properties记录到标准输出。

log4j.appender.Stdout=org.apache.log4j.ConsoleAppender
log4j.appender.Stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.Stdout.layout.conversionPattern=%-5p - %-26.26c{1} - %m\n

log4j.rootLogger=INFO,Stdout

log4j.logger.org.apache.wicket=INFO
log4j.logger.org.apache.wicket.protocol.http.HttpSessionStore=INFO
log4j.logger.org.apache.wicket.version=INFO
log4j.logger.org.apache.wicket.RequestCycle=INFO

然后：

我添加了您的所有依赖项（或修改了现有依赖项的版本以匹配您的依赖项）
- 我刚刚做了一些清理，例如在Hibernate依赖项中，您不需要全部声明它们，利用传递依赖项机制
我添加了相关和repositoriespluginRepositories
我添加了 glassfish 的依赖项以使构建通过javax.servlet
我添加了插件来测试整个事情embedded-glassfish
我做了一些其他不相关的更改
- 我将编译器设置更改为1.6
- 我在元素中声明以很好地控制可传递依赖项中的版本。slf4j-apidependencyManagement

当我使用嵌入式玻璃鱼插件运行项目时：

$ mvn package

...

并在浏览器中访问 http://localhost:8080/server，我按预期在标准输出中获取日志：

我想知道这是否具有代表性。

我已经检查了战争，log4j.properties确实在WEB-INF/类中。我没有log4j.jar，我有slf4j-log4j12.jar。

slf4j-log4j12.jar不是 log4j.jar， slf4j-log4j12 的替代品.jar是 log4J 版本 1.2 的绑定，您仍然需要 log4j.jar。来自 SLF4J 文档：

在部署时与日志记录框架绑定

如前所述，SLF4J支持各种日志记录框架。SLF4J 发行版附带了几个 jar 文件，称为“SLF4J 绑定”，每个绑定对应于一个受支持的框架。

slf4j-log4j12-1.6.1.jar：log4j 版本 1.2 的绑定，一个广泛使用的日志记录框架。您还需要将 log4j.jar放在类路径上。

我想知道你是如何在 NetBeans 和 Eclipse 下做到这一点的。

答案 2

我有完全相同的问题。

Log4j本身工作得很好：

<dependency>
   <groupId>log4j</groupId>
   <artifactId>log4j</artifactId>
   <version>1.2.16</version>
</dependency>

但是，如果我尝试使用它的Slf4j，那么我的“src/resources/log4j.properties”文件就不再找到了，即使Maven将其添加到类路径上的目录中也是如此。

因此，这不是开箱即用的：

<dependency>
   <groupId>log4j</groupId>
   <artifactId>log4j</artifactId>
   <version>1.2.16</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.6.4</version>
</dependency>
<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>jcl-over-slf4j</artifactId>
   <version>1.6.4</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jul-to-slf4j</artifactId>
    <version>1.6.4</version>
</dependency>
<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-api</artifactId>
   <version>1.6.4</version>
</dependency>

要使其工作，您必须显式地将“log4j.properties”添加到类路径中，或者告诉服务器在哪里可以找到它！实现此目的的一种方法是（此示例在 Windows 上）：

-Dlog4j.configuration=file:C:\[pathToYourProject]\trunk\target\classes\log4j.properties

在 Eclipse 中（如果这是您使用的），您可以将同一行添加到运行配置/ VM 参数中。
