目录结构
添加文件DefaultConfig.java
用于在web.xml中配置
package config;
import Model.User;
import com.jfinal.config.*;
import com.jfinal.kit.PropKit;
import com.jfinal.log.Log4jLoggerFactory;
import com.jfinal.plugin.activerecord.ActiveRecordPlugin;
import com.jfinal.plugin.druid.DruidPlugin;
import com.jfinal.render.ViewType;
import controller.HelloController;
import controller.UserController;
/**
* Created by DawnHeaven on 16-5-30.
*/
public class DefaultConfig extends JFinalConfig {
//全局设定
@Override
public void configConstant(Constants constants) {
constants.setLoggerFactory(new Log4jLoggerFactory());
constants.setEncoding("UTF-8");//设置编码
constants.setDevMode(true);
constants.setViewType(ViewType.FREE_MARKER);//设置视图模板 默认为freemarker
constants.setFreeMarkerViewExtension(".ftl");
}
@Override
public void configRoute(Routes routes) {
//匹配路径为 / 使用HelloController处理
routes.add("/", HelloController.class);
//匹配路径为 /user 使用UserController处理， 最后一个参数是，返回的视图从哪个路径下寻找
routes.add("/user", UserController.class, "/WEB-INF/template");
}
@Override
public void configPlugin(Plugins plugins) {
//配置数据库连接
PropKit.use("jdbc.properties");
final String URL =PropKit.get("jdbcUrl");
final String USERNAME = PropKit.get("user");
final String PASSWORD =PropKit.get("password");
DruidPlugin druidPlugin = new DruidPlugin(URL,USERNAME,PASSWORD);
druidPlugin.setFilters("stat,wall");
plugins.add(druidPlugin);
//注册service
ActiveRecordPlugin activeRecordPlugin = new ActiveRecordPlugin(druidPlugin);
//添加Model类和数据库表的映射。user指的是表名，userid指的是主键
activeRecordPlugin.addMapping("user","id", User.class);
plugins.add(activeRecordPlugin);
}
@Override
public void configInterceptor(Interceptors interceptors) {
}
@Override
public void configHandler(Handlers handlers) {
handlers.add(new ContextPathHandler());
}
}
web.xml中添加 filter
<filter>
<filter-name>jfinal</filter-name>

疑问
在js引入时，总是引用不到，我还没搞清楚具体的导入方法，我只是发现，我现有的目录结构下可以使用
知道的，可以提点我一下，谢谢
