--------------------编程问答--------------------
部分代码：
--------------------编程问答-------------------- "Please initialize the log4j system properly." 你加了log4j的包了吗? log4j.properties文件配置正确了吗? --------------------编程问答-------------------- 我虽是新手，不会解答问题，但我也看出问题不是log4j的，那只是两个警告而已，真正的异常是从第三句开始的。 --------------------编程问答-------------------- 检查一下的你的java代码得到'basicBrandinfoDao' 这个的时候，路径是否有误，E:\MyEclipse Workstation\AutoXmlAnalyze\bin\applicationContext.xml的配置路径都正确么？还有就是修改了xml文件后，要重启服务。 --------------------编程问答-------------------- 把 <bean id="TbBasicBrandinfoBean" class="com.scpii.auto.entity.TbBasicBrandinfo" />中的id 值首字母修改为小写：tbBasicBrandinfoBean，如果这种不行的话
