Nutz 集成Activiti5.17.0 [02]集成流程设计器及汉化
下载 activiti-modeler 源码，里面的方法用nutz重写，然后修改editor-app里面页面和js里对应的路径。
5.17.0汉化文件下载：http://pan.baidu.com/s/1qWlzHDE
细节不多述了，自己动手吧，哇哈哈……

Cordova：Toast浮动提示插件
第一步：编写插件类
package cn.xuetang.plugin;
import android.widget.Toast;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaInterface;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
/**
* Created by Wizzer on 14-8-28.
*/
public class ToastPlugin extends CordovaPlugin {
public ToastPlugin() {
}
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
if (this.cordova.getActivity().isFinishing()) return true;
if (action.equals("show")) {
this.show(args.getString(0));
} else if (action.equals("showlong")) {
this.showlong(args.getString(0));
} else {
return false;
}
callbackContext.success();
return true;
}
public void show(String message) {
Toast.makeText(this.cordova.getActivity(), Toast.LENGTH_SHORT).show();
}
public void showlong(String message) {
Toast.makeText(this.cordova.getActivity(), message, Toast.LENGTH_LONG).show();
}
}
第二步：配置 res/xml/config.xml
<feature name="ToastPlugin">
<param name="android-package" value="cn.xuetang.plugin.ToastPlugin" />
</feature>
注：这里的 feature name ，要和↓↓面讲的的js文件里一致。
第三步：创建js文件 plugins/toast.js
/**
* Created by Wizzer on 14-8-28.
*/
cordova.define("cn.xuetang.plugin.ToastPlugin", function(require, exports, module) {
var exec = require('cordova/exec');
module.exports = {
/**
* 一共5个参数
第一个 :成功回调
第二个 :失败回调
第三个 :将要调用的类的配置名字(在config.xml中配置↑↑)
第四个 :调用的方法名(一个类里可能有多个方法 靠这个参数区分)
第五个 :传递的参数 以json的格式
*/
show: function(message) {
exec(null, null, "ToastPlugin", "show", [message]);
},
showlong: function(message) {
exec(null, null, "ToastPlugin", "showlong", [message]);
}
};
});
注：js里两个方法，分别对应类中的两个方法
第四步：修改 cordova_plugins.js 引用 tocas.js
在 module.exports = [ ] 中追加如下代码：
{
"file": "plugins/toast.js",
"id": "cn.xuetang.plugin.ToastPlugin",
"merges": [
"navigator.toast"
]
}
最后：调用
navigator.toast.show("再点击一次退出");
navigator.toast.showlong("再点击一次退出");

Cordova：连续按两次返回键退出程序
/**
* Created by Wizzer on 14-8-28.
*/
var num = 0;
var login = {
initialize: function () {
this.bindEvents();
},
bindEvents: function () {
document.addEventListener('backbutton', this.eventBackButton, false);
},
eventBackButton: function () {
num++;
if (num > 1) {
navigator.app.exitApp();
}
navigator.toast.show("再点击一次退出");
// 3秒后重新计数
var intervalID = window.setInterval(function() {
num=0;
window.clearInterval(intervalID);
}, 3000);
}
};
浮动提示插件见：

JAVA：网易微博模拟登陆
网易微博登陆验证，第一次请求使用BASE64加密、第二次请求使用MD5+RSA加密，比较变态，于是使用JAVA+JS相结合的方式，调用其JS方法得到加密字符串。
/core1.7.0.js 是经过处理的，删掉几行在JAVA引用中会报错的浏览器对象。

Windows ：Nginx + PHP 配置虚拟目录
首先配置好运行环境：
其次修改nginx配置文件：
server {
listen 80;
server_name localhost;
location ~ ^/bbs/.+\.php$ {
alias E:/xuetang/cn/bbs;
rewrite /bbs/(.*\.php?) /$1 break;
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME E:/xuetang/cn/bbs$fastcgi_script_name;
include fastcgi_params;
}
location ~ ^/bbs($|/.*) {
alias E:/xuetang/cn/bbs/$1;
index index.php index.html index.htm;
}
location / {
root E:/xuetang/cn/www;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
root E:/xuetang/cn/www;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Nutz：单机负载均衡或启动多实例注意事项
1、上传文件的文件池路径问题
upload.js
filePool : {
type : “cn.xuetang.common.file.FilePool”,
args : [“/temp/”, 2000]
}
将路径改到项目的路径下
public class FilePool extends NutFilePool {
public FilePool(String homePath, long size) {
super(webinfPath(homePath), size);
}
private static final String webinfPath(String str) {
return Mvcs.getServletContext().getRealPath(“/WEB-INF”)+str;
}
}
2、Nutz大字段缓存的问题
.nutz/tmp/dao
将 org.nutz.dao.jdbc.nutz_jdbc_experts.js 拷贝到项目类路径下，修改相应的配置，文件夹不冲突即可。
