吃巧克力
昨天在公交车站等车,看见一小孩子拿了一大包巧克力在吃,一会儿吃了半袋子。我出于好心说了句:小孩子巧克力不能多吃,吃多了会得病。小孩子对我说:我爷爷今年103岁了。我说:因为吃巧克力?小孩说:不是,因为他从来不管闲事。

昨天在公交车站等车,看见一小孩子拿了一大包巧克力在吃,一会儿吃了半袋子。我出于好心说了句:小孩子巧克力不能多吃,吃多了会得病。小孩子对我说:我爷爷今年103岁了。我说:因为吃巧克力?小孩说:不是,因为他从来不管闲事。
功能比较类似于JEECMS,基于Nutz 所以二次开发非常容易,并且UI表现层完全和JEECMS不一样,主要是ajax+弹出窗口的方式。

领导在门外用门夹核桃,我从门口路过,顺嘴说了一句,用门夹过的核桃还能补脑吗?领导愣了愣,把核桃扔垃圾篓了。刚经过领导电脑桌前,看到领导在百度:门夹过的核桃为什么不能补脑?我滴个天哪,度娘你可给点靠谱答案吧,不然他不得揍死我啊。ps,领导刚从美国回来不久。。。。

项目部署根目录增加:crossdomain.xml 文件,解决上传控件跨域上传的问题(应用和文件服务器分开部署):
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd" > <cross-domain-policy> <site-control permitted-cross-domain-policies="all" /> <allow-access-from domain="*" /> <allow-http-request-headers-from domain="*" headers="*"/> </cross-domain-policy>
SWFUpload.prototype.setPostParams = function (paramsObject) {
this.settings.post_params = paramsObject;
this.callFlash(“SetPostParams”, [paramsObject]);
};
swfu.setPostParams({ path:$(“#path”).val() });
upload.json 配置文件,增加扩展配置项extOption,内容可以由用户自定义,返回一个Map对象。
我要实现功能是,用户在相册里只允许上传图片文件、视频里只允许上传视频格式的文件等,
结合上传控件和JS,实现在页面级和代码级的文件类型分类限制、分类保存等功能。
Nutz issue 提交需求不被接纳所以只好自己实现了,大家如需要的话可以提issue,希望以后Nutz能内置:
https://github.com/nutzam/nutz/issues/568
upload.json:
var ioc = { upload : { type : "org.nutz.mvc.upload.UploadAdaptor", args : [{refer : "uploadCtx"}] }, uploadCtx : { type : "org.nutz.mvc.upload.UploadingContext", args : [{refer: "filePool"}], fields : { ignoreNull : true, maxFileSize : 10485760, nameFilter : ".+(jpg|gif|png|jpeg|doc|docx|xls|xlsx|ppt|pptx|wps|pdf|txt|chm|mp3|mp4|3gp|rm|swf|flv|asf|wmv|wma|z|zip|rar|ios|jar)", extOption: { "images":"jpg,gif,png,jpeg", "document":"doc,docx,xls,xlsx,ppt,pptx,wps,pdf,txt,chm", "music":"mp3", "video":"mp4,3gp,rm,swf,flv,asf,wmv,wma", "archive":"z,zip,rar,ios,jar" } } }, filePool : { type : "com.hits.common.file.FilePool", args : ["/temp/", 2000] } };
改写Nutz源码:
org.nutz.mvc.upload.UploadingContext 类,增加代码:
/** * 一个扩展配置项,用户可自定义内容 */ private Map<String, String> extOption; public Map<String, String> getExtOption() { return extOption; } public UploadingContext setExtOption(String extOption) { this.extOption = Json.fromJsonAsMap(String.class,extOption); return this; }
增加一个调用类:
FileType.java
/** * 类描述: * 创建人:Wizzer * 联系方式:www.wizzer.cn * 创建时间:2013-12-25 下午1:13:30 * @version */ public class FileType { /** * 根据文件名获取文件类型,默认返回other * @param upload * @param suffixname * @return */ public static String getFileType(UploadAdaptor upload,String suffixname) { Map<String,String> hm=upload.getContext().getExtOption(); String str = StringUtil.null2String(suffixname).toLowerCase(); Set<Map.Entry<String, String>> set = hm.entrySet(); for (Iterator<Map.Entry<String, String>> it = set.iterator(); it.hasNext();) { Map.Entry<String, String> entry = (Map.Entry<String, String>) it.next(); if(entry.getValue().toLowerCase().indexOf(str)>-1) return entry.getKey(); } return "other"; } /** * 根据文件类型获取文件后缀名,默认返回nameFilter配置 * @param upload * @param filetype * @return */ public static String getSuffixname(UploadAdaptor upload,String filetype) { Map<String,String> hm=upload.getContext().getExtOption(); String str = StringUtil.null2String(filetype).toLowerCase(); if(!"".equals(str)){ Set<Map.Entry<String, String>> set = hm.entrySet(); for (Iterator<Map.Entry<String, String>> it = set.iterator(); it.hasNext();) { Map.Entry<String, String> entry = (Map.Entry<String, String>) it.next(); if(entry.getKey().toLowerCase().equals(str)) return entry.getValue(); } } String name=upload.getContext().getNameFilter(); return name.substring(name.indexOf("(")+1,name.lastIndexOf(")")).replace("|", ","); } }
使用示例:
@Inject protected UploadAdaptor upload; @At @Ok("->:/private/file/uploadOne.html") public void uploadOne(@Param("filetype") String filetype,HttpServletRequest req){ req.setAttribute("filetype", filetype); req.setAttribute("allowExtensions", FileType.getSuffixname(upload, filetype)); }
如上所述,在限制文件上传类型的同时,还可以将文件分类保存在不同类型的目录下。
1、先使用evasi0n7越狱;
2、进入Cydia按照提示更新Cydia到最新版;
3、Cydia软件源添加 http://apt.weiphone.com;
4、Cydia搜索afc2add选择威锋源安装;
5、使用同步助手或其他工具浏览iPhone文件系统:
浏览至目录 /System/Library/PrivateFrameworks/AppSupport.framework
用压缩包里的 Default.phoneformat 替换之,重启后即可。
为防万一最好备份此文件。

PS:CDMA iPhone 4 用了快三年了,有些毛病,坚持到明年iPhone6再换。。
由于Nutz是零配置的,所以通过URL找到处理类以及跳转的页面,就显得很麻烦,不方便维护。
于是,我在大神兽的指导下,实现如下功能:在项目启动时,将URL路径、类、方法、以及跳转页面写入项目中的一个文件中,方便查看。
@UrlMappingBy(value=UrlMappingSet.class) public class MainModule { }
在Nutz入口类,加入 @UrlMappingBy。
UrlMappingSet.java 实现在 /WEB-INF/ 目录下生成 paths.txt 文件,记录路径,文件格式如下:
UrlMappingSet.java 源码:
package com.hits.core; import java.io.File; import java.lang.reflect.Method; import org.nutz.lang.Files; import org.nutz.lang.Lang; import org.nutz.mvc.ActionChainMaker; import org.nutz.mvc.ActionInfo; import org.nutz.mvc.Mvcs; import org.nutz.mvc.NutConfig; import org.nutz.mvc.impl.UrlMappingImpl; /** * 类描述: 创建人:Wizzer 联系方式:www.wizzer.cn 创建时间:2013-12-19 下午10:36:17 * * @version */ public class UrlMappingSet extends UrlMappingImpl { private static int count = 0; public void add(ActionChainMaker maker, ActionInfo ai, NutConfig config) { super.add(maker, ai, config); printActionMappingThis(ai); } protected void printActionMappingThis(ActionInfo ai) { String[] paths = ai.getPaths(); StringBuilder sb = new StringBuilder(); if (null != paths && paths.length > 0) { sb.append(paths[0]); for (int i = 1; i < paths.length; i++) sb.append(",").append(paths[i]); } else { throw Lang.impossible(); } sb.append("\n"); // 打印方法名 Method method = ai.getMethod(); String str; if (null != method) str = String.format("%-30s : %-10s", Lang.simpleMetodDesc(method), method.getReturnType().getSimpleName()); else throw Lang.impossible(); sb.append("\t" + ai.getModuleType().getName()); sb.append("\n\r"); sb.append("\t" + str); sb.append("\n"); String filepath = Mvcs.getServletContext().getRealPath("/WEB-INF/") + "/paths.txt"; File f = new File(filepath); if (count == 0) { Files.write(f, sb.toString()); } else { Files.appendWrite(f, sb.toString()); } count++; } }
使用示例:
/** 你可以自定义取数据区间的值,如下: offset=0,count=5 取0到5的记录 offset=5,count=10 取5到15的记录 page=3, offset=15,count=20 取15到35的记录 **/ int offset=0; int count=5; ExplicitPager pager=new ExplicitPager(offset,count); QueryResult file=daoCtl.listPage(dao, Oa_doc_file.class, cri,pager);
ExplicitPager 类源码:
package com.hits.common.page; import org.nutz.dao.pager.Pager; /** * 类描述: * 创建人:Wizzer * 联系方式:www.wizzer.cn * 创建时间:2013-12-12 下午3:16:21 * @version */ public class ExplicitPager extends Pager { private static final long serialVersionUID = 1L; int offset; int count; public ExplicitPager(int offset, int count) { super(); this.offset = offset; this.count = count; } public void setOffset( int offset) { this.offset = offset; } public void setSelectCount( int count) { this.count = count; } @Override public int getPageSize() { return count; } @Override public int getOffset() { return offset; } }
分页源代码(可参考上一篇文章,实现自定义SQL多表分页区间取值):
/** * 根据查询条件分页,返回封装好的QueryResult对象 * * @param dao * @param obj * @param cnd * @param pager * @return */ public <T> QueryResult listPage(Dao dao, Class<T> obj, Condition cnd,Pager pager) { List<T> list = dao.query(obj, cnd, pager); pager.setRecordCount(dao.count(obj, cnd));// 记录数需手动设置 return new QueryResult(list, pager); } /** * 根据自定义SQL分页,返回封装好的QueryResult对象 * @param dao * @param sql * @param pager * @return */ publicQueryResult listPageSql(Dao dao, Sql sql, Pager pager) { if(pager==null) return null; pager.setRecordCount(Daos.queryCount(dao, sql.getSourceSql()));// 记录数需手动设置 sql.setPager(pager); sql.setCallback(Sqls.callback.records()); dao.execute(sql); return new QueryResult(sql.getList(Map.class), pager); }
