java - 在 hibernate 和 glassfish 3.0.1 中使用 log4j

Question

我正在尝试在 glassfish 3.0.1 上使用 JPA 设置 hibernate 3.5.3；

我正在使用 netbeans 6.9.1 企业项目；我添加了所有必需的 hibernate 文件，除了日志记录之外一切都很好......

我添加到项目类路径中，就像文档所说的那样(仅列出了与日志相关的 jar):

-slf4j-api-1.5.8.jar

-slf4j-log4j12-1.5.8.jar

-log4j-1.2.16.jar

-log4j.properties 看起来像:

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.rootLogger=info, stdout

log4j.logger.org.hibernate.test=info
log4j.logger.org.hibernate.tool.hbm2ddl=debug

我还使用 -Dlog4j.debug JVM 属性激活了调试。

一旦部署，我就会在服务器日志中看到:

SEVERE: log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable.

关于如何解决这个问题的任何想法？谢谢!

编辑

我尝试按照 Tushar Tarkas 的建议从我的项目中删除 log4j:

SEVERE: org/apache/log4j/Level
java.lang.NoClassDefFoundError: org/apache/log4j/Level
        at org.slf4j.LoggerFactory.getSingleton(LoggerFactory.java:223)
        at org.slf4j.LoggerFactory.bind(LoggerFactory.java:120)
        at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:111)
        at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:269)

EDIT2:解决方案

我不知道为什么，但是如果我在/domains/domain1/lib 中复制 log4j-1.2.16.jar 文件，它就可以工作了。

Answer 1

我可以找到一些与类似问题相关的讨论。问题出在 glassfish 版本 3 及更高版本。这些类似乎由不同的类加载器加载。
