一.錯誤信息提示:
WARN [main] (Configurator.java:126) - No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: jar:file:/E:/Users/algz/workspace/.metadata/.plugins/com.genuitec.eclipse.easie.tomcat.myeclipse/tomcat/webapps/item/WEB-INF/lib/ehcache-1.1.jar!/ehcache-failsafe.xml

解決方案:
ehcache-1.1.jar 包下的ehcache-failsafe.xml 文件復制到 src 目錄下(新建文件,復制內容).

二.錯誤信息提示:
log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

解決方案:
src 目錄下創建 log4j.properties 文件(具體內容,詳見log4j配置文件).

解決方案:
Spring 和 Hibernate 共用的一些 jar 文件發生了版本沖突, 刪除 WEB-INF/lib/asm-2.2.3.jar 然后重啟 Tomcat.

四.錯誤提示:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'SessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V  
...
Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

解決方法:
并不是真正的bean name錯了,也不是找不到他的方法.是asm-2.2.3.jar與asm.jar沖突.
正確的刪除asm-2.2.3.jar方法是到項目的發布文件夾\WEB-INF\lib中刪除,不能用MyEclipse里刪除.因為他在發布時仍沒刪除.
