帝国CMS:头部导航栏当前栏目高亮

/e/class/userfun.php

function currentPage($classid,$thisid){
        global $class_r;
        $fr=explode('|',$class_r[$classid][featherclass]);
        $topbclassid=$fr[1]?$fr[1]:$classid;//取得第一级栏目id
        if ($topbclassid==$thisid) {
                  echo "class='cur'";
                }
        else {
        }
}

头部模板:

<ul>
<li <?php  if(empty($GLOBALS[navclassid])){echo "class='cur'";} ?>><a id="nav-hover0" href="[!--news.url--]">首页</a></li>
<?php 
$i=0;
$path="";
?>
[e:loop={'select classid,classname,classpath,wburl from [!db.pre!]enewsclass where bclassid=0 order by classid',0,24,0}]
<?php

  $path=$public_r[newsurl].$bqr[classpath];
  if(!empty($bqr[wburl])){
      $path=$bqr[wburl];

Windows :Nginx + PHP 配置虚拟目录

首先配置好运行环境:

windows下配置nginx+php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;
            include        fastcgi_params;
        }
}

注意虚拟目录配置要在根目录上面。。

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。

Linux:后台执行Java类

编写执行文件 job.sh

#!/bin/sh
CLASSPATH=classes:lib/druid-1.0.1.jar:lib/htmlparser-1.6.jar:lib/log4j-1.2.17.jar:lib/mysql-connector-java-5.1.26-bin.jar:lib/nutz-1.b.50.jar:lib/ojdbc14.jar:lib/quartz-2.2.1.jar:lib/quartz-jobs-2.2.1.jar:lib/slf4j-api-1.6.6.jar:lib/slf4j-log4j12-1.6.6.jar:lib/sqljdbc4.jar:lib/commons-pool2-2.2.jar:
#export CLASSPATH
java -classpath $CLASSPATH cn.xuetang.job.MyJob &

 赋予job.sh 执行权限

chmod a+x job.sh

后台执行,并把标准输出重定向,关闭终端仍在执行

nohup bash /home/work/ImageTask/job.sh > success.log 2>error.log &

输出在当前控制台,关闭该终端时,将退出启动的进程

/home/work/ImageTask/job.sh

每两分钟启动一次,关闭终端不影响任务

crontab -e

*/2 * * * * /home/work/ImageTask/job.sh > success.log 2>error.log &

买了一副耳环,还好,价格也不算贵,30万不到

 两个女的在电梯里聊天,“我和我老公昨天晚上没事,就看看首饰,本来想买个手镯,后来没有相中的,就买了一副耳环,还好,价格也不算贵,30万不到,我老公说,你要是喜欢就买了吧,我说行,还挺不错的,就是有点遗憾,现在带不了。”
另一个女人问:“为什么?”
“80级才能带,现在等级不够!”

Nutz:结合文件池实现网络下载文件,压缩成zip后下载

入口函数:
@At
public void downImage(@Param(“tvid”) int tvid, HttpServletResponse resp, HttpServletRequest req) {

}

使用Nutz文件池:

Globals.FILE_POOL= new NutFilePool(“~/tmp/myfiles”, 10);

源码:

int i = 0;
            File f = Globals.FILE_POOL.createFile(".zip");
            ZipOutputStream out = new ZipOutputStream(new FileOutputStream(f.getAbsolutePath()));
            for (Weixin_image image : list) {
                i++;
                String filename = Strings.sNull(bbinfo.get(image.getUid())) + "_" + Strings.sNull(userinfo.get(image.getUid())) + "_" + i+".jpg";
                String picurl = image.getPicurl();
                if (!Strings.isBlank(image.getImage_url())) {
                    picurl = image.getImage_url();
                }
                URL url = new URL(picurl);
                try {
                    URLConnection conn = url.openConnection();
                    InputStream inStream = conn.getInputStream();
                    byte[] buffer = new byte[1204];
                    out.putNextEntry(new ZipEntry(filename));
                    while ((byteread = inStream.read(buffer)) != -1) {
                        bytesum += byteread;
                        out.write(buffer, 0, byteread);
                    }
                    out.closeEntry();
                    inStream.close();

                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();

Nutz:结合Jedis实现Redis消息订阅和缓存队列(支持自动重连)

仅作参考。
编辑配置Nutz redis配置文件:

var ioc = {
        jedisConfig : {
            type : 'cn.xuetang.common.redis.JedisConfig',
            fields : {
                maxTotal : 200,
                maxIdle : 10,
                maxWaitMillis:10001,
                testOnBorrow:true,
                redisUrl:'127.0.0.1',
                redisPort:6379,
                redisTimeout:1000
            }
        }
}
package cn.xuetang.common.redis;

/**
 * Created by Wizzer on 14-4-8.
 */
public class JedisConfig {
    private int maxTotal;
    private int maxIdle;
    private int maxWaitMillis;
    private boolean testOnBorrow;
    private String redisUrl;
    private int redisPort;
    private int redisTimeout;//redis断开后自动重新连接间隔时间

    public int getMaxTotal() {
        return maxTotal;
    }

    public void setMaxTotal(int maxTotal) {
        this.maxTotal = maxTotal;
    }

    public int getMaxIdle() {
        return maxIdle;
    }

    public void setMaxIdle(int maxIdle) {
        this.maxIdle = maxIdle;
    }

    public int getMaxWaitMillis() {
        return maxWaitMillis;
    }

    public void setMaxWaitMillis(int maxWaitMillis) {
        this.maxWaitMillis = maxWaitMillis;
    }

    public boolean isTestOnBorrow() {
        return testOnBorrow;
    }

    public void setTestOnBorrow(boolean testOnBorrow) {
        this.testOnBorrow = testOnBorrow;
    }

    public String getRedisUrl() {
        return redisUrl;
    }

    public void setRedisUrl(String redisUrl) {
        this.redisUrl = redisUrl;
    }

    public int getRedisPort() {
        return redisPort;
    }

    public void setRedisPort(int redisPort) {
        this.redisPort = redisPort;
    }

    public int getRedisTimeout() {
        return redisTimeout;
    }

    public void setRedisTimeout(int redisTimeout) {
        this.redisTimeout = redisTimeout;
    }
}

Nutz入口类加载配置文件,config路径:

@Modules(scanPackage=true)
@Ok("raw")
@Fail("http:500")
@IocBy(type=ComboIocProvider.class,args={
	"*org.nutz.ioc.loader.json.JsonLoader","config",
	"*org.nutz.ioc.loader.annotation.AnnotationIocLoader","cn.xuetang"})
@SetupBy(value=StartSetup.class)
@UrlMappingBy(value=UrlMappingSet.class)
public class MainModule {
}

初始化配置参数,新建订阅消息处理线程:

    public static JedisConfig REDIS_CONFIG;
    //声明全局的redis连接池
    public static ShardedJedisPool SHARDEDJEDIS_POOL=null;
    public static JedisPool JEDIS_POOL=null;

    public static void InitRedisConfig() {//初始化redis
        REDIS_CONFIG = Mvcs.ctx.getDefaultIoc().get(JedisConfig.class);
        JedisPoolUtil jedisPoolUtil=new JedisPoolUtil();
        SHARDEDJEDIS_POOL = jedisPoolUtil.getShardedJedisPool();
        JEDIS_POOL = jedisPoolUtil.getJedisPool();
    }

    new Thread(Mvcs.getIoc().get(ImageTask.class)).start();

 
创建Jedis连接池工具类:

package cn.xuetang.common.redis;

import cn.xuetang.common.config.Globals;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
import redis.clients.jedis.JedisShardInfo;
import redis.clients.jedis.ShardedJedisPool;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by Wizzer on 14-4-8.
 */
public class MyJedis {
    private String redisUrl;
    private int redisPort;
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(Globals.REDIS_CONFIG.getMaxTotal());
        jedisPoolConfig.setMaxIdle(Globals.REDIS_CONFIG.getMaxIdle());
        jedisPoolConfig.setMaxWaitMillis(Globals.REDIS_CONFIG.getMaxWaitMillis());
        jedisPoolConfig.setTestOnBorrow(Globals.REDIS_CONFIG.isTestOnBorrow());
        return jedisPoolConfig;
    }
    public JedisShardInfo jedisShardInfo(){
        return new JedisShardInfo(redisUrl, redisPort);
    }
    public JedisPool jedisPool(){
        return new JedisPool(jedisPoolConfig(),redisUrl, redisPort);
    }
    public ShardedJedisPool shardedJedisPool(){
        this.redisUrl=Globals.REDIS_CONFIG.getRedisUrl();
        this.redisPort=Globals.REDIS_CONFIG.getRedisPort();
        List<JedisShardInfo> jedisList = new ArrayList<JedisShardInfo>();
        jedisList.add(jedisShardInfo());
        return new ShardedJedisPool(jedisPoolConfig(), jedisList);
    }

}

实现自己的监听类:

package cn.xuetang.common.redis;

import org.nutz.log.Log;
import org.nutz.log.Logs;
import redis.clients.jedis.JedisPubSub;

/**
 * 订阅监听类
 * Created by Wizzer on 14-4-8.
 */
public class MyJedisListenter extends JedisPubSub {
    private final static Log log = Logs.get();
    // 取得订阅的消息后的处理
    public void onMessage(String channel, String message) {
        log.info(channel + "=" + message);
    }

    // 初始化订阅时候的处理
    public void onSubscribe(String channel, int subscribedChannels) {
        log.info(channel + "=" + subscribedChannels);
    }

    // 取消订阅时候的处理
    public void onUnsubscribe(String channel, int subscribedChannels) {
        log.info(channel + "=" + subscribedChannels);
    }

    // 初始化按表达式的方式订阅时候的处理
    public void onPSubscribe(String pattern, int subscribedChannels) {
        log.info(pattern + "=" + subscribedChannels);
    }

    // 取消按表达式的方式订阅时候的处理
    public void onPUnsubscribe(String pattern, int subscribedChannels) {
        log.info(pattern + "=" + subscribedChannels);
    }

    // 取得按表达式的方式订阅的消息后的处理
    public void onPMessage(String pattern, String channel, String message) {
        log.info(pattern + "=" + channel + "=" + message);
    }
}

 
获取单例Jedis连接池:

package cn.xuetang.common.redis;

import cn.xuetang.common.config.Globals;
import org.nutz.log.Log;
import org.nutz.log.Logs;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.ShardedJedisPool;

import java.util.Date;

/**
 * Created by Wizzer on 14-4-8.
 */
public class JedisPoolUtil {
    private final static Log log = Logs.get();

    public synchronized ShardedJedisPool getShardedJedisPool() {
        if (Globals.SHARDEDJEDIS_POOL == null) {
            MyJedis myJedis=new MyJedis();
            Globals.SHARDEDJEDIS_POOL = myJedis.shardedJedisPool();
        }
        return Globals.SHARDEDJEDIS_POOL;
    }

    public synchronized JedisPool getJedisPool() {
        if (Globals.JEDIS_POOL== null) {
            MyJedis myJedis=new MyJedis();
            Globals.JEDIS_POOL = myJedis.jedisPool();
        }
        return Globals.JEDIS_POOL;
    }
}

数据入列同时发布订阅消息:

ShardedJedis shardedJedis=Globals.SHARDEDJEDIS_POOL.getResource();
                txt.put("appid", appInfo.getId());
                shardedJedis.lpush("image", Json.toJson(txt));
                Jedis jedis=Globals.JEDISPOOL.getResource();
                jedis.publish("newimage","true");

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。

基于Nutz的CMS内容管理系统大功告成

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。

Nutz:上传文件的配置项扩展,实现对文件类型的限制及分类

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:

			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。

CDMA iPhone 4 iOS7.0.4/7.1 越狱并解决联系人括号问题的办法

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。

绿色evasi0n7及Default.phoneformat 文件下载:http://pan.baidu.com/s/1nt16UgD

 

PS:CDMA iPhone 4 用了快三年了,有些毛病,坚持到明年iPhone6再换。。

Nutz:通过URL路径查找对应的类及入口函数

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:

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;

			str = String.format("%-30s : %-10s", Lang.simpleMetodDesc(method),
