Spring3.1啟動時報錯: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.springframework.core.CollectionFactory.<clinit>(CollectionFactory.java:64) at org.springframework.core.SimpleAliasRegistry.<init>(SimpleAliasRegistry.java:41) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.<init>(DefaultSingletonBeanRegistry.java:73) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.<init>(FactoryBeanRegistrySupport.java:41) at org.springframework.beans.factory.support.AbstractBeanFactory.<init>(AbstractBeanFactory.java:146) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.<init>(AbstractAutowireCapableBeanFactory.java:144) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.<init>(AbstractAutowireCapableBeanFactory.java:155) at org.springframework.beans.factory.support.DefaultListableBeanFactory.<init>(DefaultListableBeanFactory.java:121) at org.springframework.beans.factory.xml.XmlBeanFactory.<init>(XmlBeanFactory.java:72) at org.springframework.beans.factory.xml.XmlBeanFactory.<init>(XmlBeanFactory.java:61) at spring.test.SpringTest.main(SpringTest.java:12) Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source)
解決方案:缺少 commons-logging.jar,也可以新增commons-logging-1.0.4.jar,建議使用後者或者更新版本。
