sqlite web配置注意事项

本篇文章主要介绍了"sqlite web配置注意事项"，主要涉及到NHibernate,Spring,Exception,JDBC方面的内容，对于SQLite感兴趣的同学可以参考一下： 1.环境a.Spring 4.1.4.RELEASEb.sqlite3c.maven3d.sqlite-JDBC 3.8.11.22.遇到问题1.方言找不到2....

1.环境

a.Spring 4.1.4.RELEASE

b.sqlite3

c.maven3

d.sqlite-JDBC 3.8.11.2

2.遇到问题

1.方言找不到

2.org.sqlite.JDBC找不到

3.想把数据库文件放到相对路径下

3.解决方案

1.官方貌似没有方言文件，大都是DIY的，自己找到一篇，生成之后配到方言中

2.把jar包扔到tomcat/lib下就好了

3.传说中配置url用resource::指定就可以了，然而并没有什么卵用，不知道是不是RP问题，配置文件贴下仅供参考

 4.引用文章什么的找不到了，先鸣谢，下次找到补上

以上就介绍了sqlite web配置注意事项，包括了NHibernate,Spring,Exception,JDBC方面的内容，希望对SQLite有兴趣的朋友有所帮助。
