我应该在哪里放置log4j.properties文件？ [英] Where should I put the log4j.properties file?

问题描述

我使用netbeans 6.7.1和glassfish v2.1编写了一个web服务项目，将log4j.properties放到项目的根目录中并使用：

 静态记录器记录器= Logger.getLogger（MyClass.class）; 
  

在构造函数中：

  PropertyConfigurator.configure（ log4j.properties）; 
  

以及函数：

  logger.info（ ...）; 
 logger.error（...）; 
 // ... 
  

但是，它是错误信息（实际上，我试过了几乎所有可以实现的目录）：

  log4j：ERROR无法读取配置文件[log4j.properties]。 
 java.io.FileNotFoundException：log4j.properties（系统找不到指定的文件）
在java.io.FileInputStream.open（Native Method）
在java.io.FileInputStream。< （FileInputStream.java:66）
 at org.apache.log4j.PropertyConfigurator.doConfigure（PropertyConfigurator.java ：297）
 at org.apache.log4j.PropertyConfigurator.configure（PropertyConfigurator.java:315）
 at com.corp.ors.demo.OrsDemo.main（OrisDemo.java:228）
 log4j：错误忽略配置文件[log4j.properties]。 
 log4j：WARN记录器没有找到appender（com.corp.ors.demo.OrsDemo）。 
 log4j：WARN请正确初始化log4j系统。

解决方案

我知道回答这个问题有点迟，也许你已经找到了解决方案，但是我发布了我找到的解决方案（在我搜索了很多）之后，它可能会有所帮助：

1. 将log4j.properties放置在项目的WEB-INF \ classes下，如前面在此线程中提到的。
   
2. 将log4j-在WEB-INF \ lib下的xx.jar
   
3. 测试log4j是否已加载：add -Dlog4j.debug @ Tomcat的java选项

希望这会对您有所帮助。 $ b

I wrote a web service project using netbeans 6.7.1 with glassfish v2.1, put log4j.properties to the root dir of project and use:

static Logger logger = Logger.getLogger(MyClass.class);

in Constructor:

PropertyConfigurator.configure("log4j.properties");

and in functions:

logger.info("...");
logger.error("...");
// ...

but, it is error info(actually, I have tried to put it almost every dir that I could realize):

log4j:ERROR Could not read configuration file [log4j.properties].
java.io.FileNotFoundException: log4j.properties (The system cannot find the file specified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:106)
        at java.io.FileInputStream.<init>(FileInputStream.java:66)
        at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:297)
        at org.apache.log4j.PropertyConfigurator.configure(PropertyConfigurator.java:315)
        at com.corp.ors.demo.OrsDemo.main(OrisDemo.java:228)
log4j:ERROR Ignoring configuration file [log4j.properties].
log4j:WARN No appenders could be found for logger (com.corp.ors.demo.OrsDemo).
log4j:WARN Please initialize the log4j system properly.

the example project could be get from http://www.91files.com/?N3F0QGQPWMDGPBRN0QA8

解决方案

I know it's a bit late to answer this question, and maybe you already found the solution, but I'm posting the solution I found (after I googled a lot) so it may help a little:

1. Put log4j.properties under WEB-INF\classes of the project as mentioned previously in this thread.
2. Put log4j-xx.jar under WEB-INF\lib
3. Test if log4j was loaded: add -Dlog4j.debug @ the end of your java options of tomcat

Hope this will help.
