jfinal 启动时出现 Can not create instance of class: com.demo.common.DemoConfig错误

[ks_jack]

刚开始学习jfinal框架，按照文档step by step 创建了一个项目，启动时却出现了 Can not create instance of class: com.demo.common.DemoConfig错误。找了一圈问题，最后发现是web.xml配置文件里面参数有问题。<init-param>
<param-name>configClass</param-name>
<param-value>com.demo.DemoConfig</param-value>
</init-param>
根据项目的包架构，改成了<init-param>
<param-name>configClass</param-name>
<param-value>demo.DemoConfig</param-value>
</init-param>
清楚缓存，重新启动。OK ！
