JFinal连接数据库

1.导入jar包

lib

2.配置数据源和插件

@Override
    public void configPlugin(Plugins me) {
        DruidPlugin dp = new DruidPlugin("jdbc:mysql://localhost/test", "root", "123456");
        me.add(dp);
        ActiveRecordPlugin arp = new ActiveRecordPlugin(dp);
        me.add(arp);
        arp.addMapping("user", User.class);

//        C3p0Plugin c3p0=new C3p0Plugin("jdbc:mysql://localhost/test", "root", "123456");
//        me.add(c3p0);
//        ActiveRecordPlugin activeRecord=new ActiveRecordPlugin(c3p0);
//        activeRecord.addMapping("user",User.class);
//        me.add(activeRecord);
    }

3.在Controller中实现自己的业务逻辑

public class HelloController extends Controller {
    public void index(){
        new User().set("name", "my").set("age", 25).save();
    }
}
