一、获取商品列表，设置路径
@RequestMapping("/createAllGoodsHtml")
public void createAllGoodsHtml() throws Exception{
        System.out.print("手动生成全部商品----->>>");
List<Long> goodsInfoIdlist=goodsInfoNServiceImpl.queryAllGoodsInfoId();
        if(CollectionUtils.isNotEmpty(goodsInfoIdlist)){
            String pcPath=CreateHtmlUtil.FILEPATH+"/pc/goods/";//添加文件夹用于区分功能
String wapPath= CreateHtmlUtil.FILEPATH+"/wap/goods/";//添加文件夹用于区分功能
File pcfile=new File(pcPath);
            if(!pcfile.exists()){
                pcfile.mkdirs();
}
            File wapfile=new File(wapPath);
            if(!wapfile.exists()){
                wapfile.mkdirs();
}
//            System.out.println("商品静态化完成！！！");
CreateHtmlThread createHtmlThread=new CreateHtmlThread(1,goodsInfoIdlist);
            int threadCount=CreateHtmlUtil.THREAD_COUNT;
            for(int i=0;i<threadCount;i++){
new Thread(createHtmlThread).start();
}
        }
    }

二、工具类编写


public class CreateHtmlThread implements Runnable {
private int type;//1商品 2文章 3问答
private List<Long> longList= Collections.synchronizedList(new ArrayList<Long>());
    public CreateHtmlThread(int t, List<Long> list){
this.type=t;
        this.longList=list;
}
@Override
public void run() {
while(longList.size()>0){
            Long id=longList.get(longList.size()-1);
            if(id!=null) {
longList.remove(id);
}
if(type==1){
                createGoodsById(id);
}else if(type==2){
                createArticleById(id);
}else if(type==3){
                createAskById(id);
}
try {
                Thread.sleep(1000);
} catch (InterruptedException e) {
                e.printStackTrace();
}
        }
    }
public void createGoodsById(Long goodsInfoId){
        String pcUrl=CreateHtmlUtil.PC_GOODS_URL+goodsInfoId+".html";
String pcPath1=CreateHtmlUtil.FILEPATH+"/pc/goods/"+"goods-10000"+goodsInfoId+".html";//生成地址
CreateHtmlUtil.createStaticPage(pcUrl,pcPath1,goodsInfoId);//生成PC商品静态页
String wapUrl=CreateHtmlUtil.WAP_GOODS_URL+goodsInfoId+".html";
String wapPath1=CreateHtmlUtil.FILEPATH+"/wap/goods/"+"goods-"+goodsInfoId+".html";//生成地址
CreateHtmlUtil.createStaticPage(wapUrl,wapPath1,goodsInfoId);//生成WAP商品静态页
}
}
三、工具类编写二


import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
public class CreateHtmlUtil {
public final static String PC_GOODS_URL="http://pc.localhost/goods-s-10000";//PC商品页面
public final static String WAP_GOODS_URL="http://m.localhost/goods-s-";//WAP商品页面
public final static String PC_ARTICLE_URL="http://pc.localhost/zixun/show-s-";
    public final static String WAP_ARTICLE_URL="http://m.localhost/zixun-s-";
    public final static String PC_ASK_URL="http://pc.localhost/ask/question-s-";
    public final static String WAP_ASK_URL="http://m.localhost/ask-s-";
    public final static String FILEPATH="/data/cache";
    public final static int THREAD_COUNT=12;//线程总数
public final static String XIAONENG="40827,35807,40563,35820";//需要替换小能的商品
public final static String XIAONENG_KF_OLD="kf_9704_1413527196072";//替换前小能组
public final static String XIAONENG_KF_NEW="kf_9704_1486619114220";//替换后小能组

        URL url = new URL(pageUrl);

        int state=connection.getResponseCode();

        if(state==200) {
            InputStream is = connection.getInputStream();

String line = null;
            while ((line = br.readLine()) != null) {
                sb.append(line).append("

}
        }else{
            File file = new File(CreateHtmlUtil.FILEPATH + "/errorlog.txt");
FileOutputStream fileout = new FileOutputStream(file,true);

fileout.write(str.toString().getBytes());

}

    }

}
writeStringToFile(filePath, pageStr);
}catch(Exception e){
            e.printStackTrace();

    }
