sqlite web配置注意事项

来源:网络整理     时间:2015-11-26     关键词:NHibernate,Spring,Exception,JDBC

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

<bean 
            destroy-method="close"> 
        <property name="driverClassName" value="org.sqlite.JDBC" /> 
        <property name="url" value="JDBC:sqlite::resource:vote.db" />
        <property name="maxIdle" value="10"/>
        <property name="maxActive" value="100"/>
        <property name="maxWait" value="10000"/>
        <property name="validationQuery" value="select 1"/>
        <property name="testOnBorrow" value="false"/>
        <property name="testWhileIdle" value="true"/>
        <property name="timeBetweenEvictionRunsMillis" value="1200000"/>
        <property name="minEvictableIdleTimeMillis" value="1800000"/>
        <property name="numTestsPerEvictionRun" value="5"/>
        <property name="defaultAutoCommit" value="true"/>

 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。
