一.错误信息提示:
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

解决方案:
ehcache-1.1.jar 包下的ehcache-failsafe.xml 文件复制到 src 目录下(新建文件,复制内容).

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

解决方案:
src 目录下创建 log4j.properties 文件(具体内容,详见log4j配置文件).

解决方案:
Spring 和 Hibernate 共用的一些 jar 文件发生了版本冲突, 删除 WEB-INF/lib/asm-2.2.3.jar 然后重启 Tomcat.

四.错误提示:
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

解决方法:
并不是真正的bean name错了,也不是找不到他的方法.是asm-2.2.3.jar与asm.jar冲突.
正确的删除asm-2.2.3.jar方法是到项目的发布文件夹\WEB-INF\lib中删除,不能用MyEclipse里删除.因为他在发布时仍没删除.
