标签： eclipse spring maven-2 tomcat maven

我使用SpringFramework3.0.3.RELEASE进行Web应用程序，在Eclipse中使用m2eclipse插件开发并部署到Tomcat6.0.26中。我可以从Eclipse运行它，但是当复制目标WAR int同一个tomcat实例（首先删除WTP webapp）并重启时，我看到以下异常：

我已经检查过，唯一的org.apache.log4j.Logger.class文件位于我的应用程序的log4j-1.2.14.jar中。 LogManager存在于同一个包中，但报告为错过。我的pom.xml：

是否有人知道问题是什么以及如何解决？

3 个答案:

答案 0 :(得分：2)

NoClassDefFoundError: Could not initialize class org.apache.log4j.LogManager

此跟踪表示static org.apache.log4j.LogManager初始化块中存在问题。

我没有完整的解释，但我会先从你的依赖中做一些清理，它们有点乱：

  • 为什么你有几个版本的Hibernate JAR（3.5.0-Final和3.5.1-Final）。你应该让它们融合。
  • Hibernate使用SLF4J，你为什么不对log4j有任何绑定？
  • Spring使用commons-logging，我会将其配置为使用SLF4J来避免任何冲突和潜在的类加载问题。有关完整说明，请参阅Logging Dependencies in Spring。

最后一点是IMO最重要的。

答案 1 :(得分：0)

app4类路径上的log4j属性文件是什么？ LogManager可能会将其用作静态资源，如果缺少则不会初始化。

答案 2 :(得分：0)

Pascal的答案包含指向有用的“Spring中的Logging Dependencies”一文的链接。它描述了如何覆盖旧的commons-logging jar并使用slf4j或log4j。问题是log4j与commons-logging冲突。从spring-context的maven依赖项中排除它，解决了这个问题。但是，我仍然不明白为什么问题仅适用于手动部署，如果从Eclipse运行webapp，则不会发生这种情况？
