Jfinal 学习1
作为一名新人程序员，可能写的不堪入目，但请轻喷，欢迎建议，作为一个野路子，肯定是有很多问题的。
使用jfinal jfinal-weixin 一个测试微信号做学习，数据库使用mysql，内网映射使用ngrok cn。
新建项目：web project
添加jar包：jfinal-2.2.jar、jfinal-weixin-1.7.jar、log4j、jackson、jetty、c3p0
配置web.xml
<filter> <filter-name>jfinal</filter-name> <filter-class>com.jfinal.core.JFinalFilter</filter-class> <init-param> <param-name>configClass</param-name> <param-value>tool.config.Config</param-value> </init-param> </filter> <filter-mapping> <filter-name>jfinal</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
配置数据库，因为是学习，暂时只是新建一份数据库，无表
create database if not exists wxtool default charset utf8 collate utf8_general_ci;
配置相关参数，在src目录下新建一个config.txt，内容：
jdbcUrl = jdbc:mysql://127.0.0.1/wxtool?autoReconnect=true&useSSL=false&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull user = root password = amin0125 devMode = true appId = wx71bfa64ba8e6c873 appSecret = d4624c36b6795d1d99dcf0547af5443d token = chmin
前三个数据库参数，devMode是是否打印相关开发信息，后三个是微信配置
新建包tool.config，新建类Config（参考demo）
public class Config extends JFinalConfig {
@Override
public void configConstant(Constants me) {
PropKit.use("config.txt");
me.setDevMode(PropKit.getBoolean("devMode", false));
}
@Override
public void configRoute(Routes me) {
}
@Override
public void configPlugin(Plugins me) {
C3p0Plugin C3p0Plugin = createC3p0Plugin();
me.add(C3p0Plugin);
ActiveRecordPlugin arp = new ActiveRecordPlugin(C3p0Plugin);
me.add(arp);
}
@Override
public void configInterceptor(Interceptors me) {
}
@Override
public void configHandler(Handlers me) {
}
public static C3p0Plugin createC3p0Plugin() {
return new C3p0Plugin(PropKit.get("jdbcUrl").trim(), PropKit.get("user").trim(), PropKit.get("password").trim());
}
}
新建包 tool.controller,新建类 WxMsgCon,其实可以继承MsgControllerAdapter来减少需要实现的方法，本着学习的原因，直接继承了MsgController
public class WxMsgCon extends MsgController {
@Override
public ApiConfig getApiConfig() {
// TODO Auto-generated method stub
}
@Override
protected void processInTextMsg(InTextMsg inTextMsg) {
// TODO Auto-generated method stub
}
@Override
protected void processInImageMsg(InImageMsg inImageMsg) {
// TODO Auto-generated method stub
}
@Override
protected void processInVoiceMsg(InVoiceMsg inVoiceMsg) {
// TODO Auto-generated method stub
}
@Override
protected void processInVideoMsg(InVideoMsg inVideoMsg) {
// TODO Auto-generated method stub
}
@Override
protected void processInShortVideoMsg(InShortVideoMsg inShortVideoMsg) {
// TODO Auto-generated method stub
}
@Override
protected void processInLocationMsg(InLocationMsg inLocationMsg) {
// TODO Auto-generated method stub
}
@Override
protected void processInLinkMsg(InLinkMsg inLinkMsg) {
TODO Auto-generated method stub
}
@Override
protected void processInCustomEvent(InCustomEvent inCustomEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInFollowEvent(InFollowEvent inFollowEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInQrCodeEvent(InQrCodeEvent inQrCodeEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInLocationEvent(InLocationEvent inLocationEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInMassEvent(InMassEvent inMassEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInMenuEvent(InMenuEvent inMenuEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInSpeechRecognitionResults(InSpeechRecognitionResults inSpeechRecognitionResults) {
// TODO Auto-generated method stub
}
@Override
protected void processInTemplateMsgEvent(InTemplateMsgEvent inTemplateMsgEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInShakearoundUserShakeEvent(InShakearoundUserShakeEvent inShakearoundUserShakeEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInVerifySuccessEvent(InVerifySuccessEvent inVerifySuccessEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInVerifyFailEvent(InVerifyFailEvent inVerifyFailEvent) {
// TODO Auto-generated method stub
}
@Override
protected void processInPoiCheckNotifyEvent(InPoiCheckNotifyEvent inPoiCheckNotifyEvent) {
// TODO Auto-generated method stub
}
}
在getApiConfig中配置一下微信参数
@Override
public ApiConfig getApiConfig() {
ApiConfig ac = new ApiConfig();
ac.setToken(PropKit.get("token"));
ac.setAppId(PropKit.get("appId"));
ac.setAppSecret(PropKit.get("appSecret"));
return ac;
}
新建包tool.service，新建类TextMsgService
public class TextMsgService {
public static TextMsgService me = new TextMsgService();
public OutMsg mappingKeyword(InTextMsg inTextMsg) {
OutTextMsg outTextMsg = new OutTextMsg(inTextMsg);
outTextMsg.setContent("你输入的文字信息是：" + inTextMsg.getContent());
return outTextMsg;
}
}
在tool.controller.WxMsgCon的processInTextMsg方法中添加如下方法：
protected void processInTextMsg(InTextMsg inTextMsg) {
render(TextMsgService.me.mappingKeyword(inTextMsg));
}
打开tool.config报下的Config类的configRoute方法，添加一行
me.add("/wxMsg", WxMsgCon.class);
右键项目，选择debug As Java Application启动，输入jfinal，启动，看到控制台如下输出
Starting JFinal 2.2 Starting scanner at interval of 5 seconds. Starting web server on port: 80 Starting Complete. Welcome To The JFinal World :)
启动ngrok
ngrok -config ngrok.cfg -subdomain chmin 80
登陆微信公众平台，配置URL和token
URL http://chmin.ngrok.natapp.cn/wxMsg Token chmin
打开微信，关注公众号，发送一条文字信息，效果如图：
说明配置成功。
