如下图，我已经解决的需求是标黄的部分，剩余需求就只有 热词分类、目录生成、热词关系图展示、数据报告导出 四部分了，这些需求是最紧要完成的，呼~撸起袖子加油干！
1、热词分类
老师说要参照各大平台的分类，我就直接按照博客园的分类来吧（我实在看不懂那些机器学习是怎么实现的，连入门的门槛都远远不及）！如下图，可以看到 博客园的新闻将新闻分成了如下几类：互联网类、IT业界类、软件开发类、开源类、电脑硬件类、游戏类、创业类、手机相关类、科学类、其他类。我就根据这几类将对应类新闻里爬出来的数据进行对应类的划分。（看来又要重新爬数据了啊）
开始爬之前事先说明一下，这次改动应该是最后一次改动了，另外我发现每一类新闻都有 100 页，这...相当于每一类都有，所以不保证有误差的存在，另外为了减少数据量，我打算将 “频数为15” 这一条件上升到 “频数为20”，不然怎么爬的完？我先预算一下，今天和明天一起写这个博客，另外明天的话，就再写一份总结性的博客，这个小目标就算完结吧！当然最后可能会加入微信小程序部分或者APP部分，到时候再说。
根据这10类新闻，我们总共要爬取些什么数据呢？
首先，通过带有 header 的 request 方式爬取 https://news.cnblogs.com/ 这一初始链接，要爬以上 10 类新闻的链接，再爬取类中封装链接的构造，并开启新的爬取，对应每一类数据给爬到的热词信息后面追加一个“热词类型”的标签，这需要我们改造 KeyWords 类，向 KeyWords 类中加入 kind 属性，改写 __toString() 成员函数。之后改造调用过 KeyWords 类的地方。(News不需要)
关于分类页面的构造方法：
首先是原新闻网址：https://news.cnblogs.com/
其次，以 “互联网” 为例：https://news.cnblogs.com/n/c1101
然后是第 100 页的地址：https://news.cnblogs.com/n/c1101?page=100
很容易的判断到是在原网址的基础上加入对应 互联网的 a 标签上的 href 链接，需要将数据加载到一起来组成爬取链接！
但是爬的过程中发现了问题，就是我爬不到对应的分类链接，既然这样，我只能人工地获取它们的链接了，就10条数据无所谓了，本来因为懒想让网页帮我做的，看来是博客园让我勤快的。哈哈哈！
对应链接：
互联网类：https://news.cnblogs.com/n/c1101
IT业界类：https://news.cnblogs.com/n/c1102
软件开发类：https://news.cnblogs.com/n/c1103
开源类：https://news.cnblogs.com/n/c1109
电脑硬件类：https://news.cnblogs.com/n/c1111
游戏类：https://news.cnblogs.com/n/c1110
创业类：https://news.cnblogs.com/n/c1112
手机相关类：https://news.cnblogs.com/n/c1113
科学类：https://news.cnblogs.com/n/c1114
其他类：https://news.cnblogs.com/n/c1199
在 Surapity 类 中建立字典，存储类型的名称和对应链接。
爬取时间较长，从下午4：51到现在第2天的1：44，过程曲折且难以简言明之。
途中遇到好几个网站会使爬虫程序终止，比如 其他类的 Apple Watch UI动效解析 ，呜哇~试一次，卡一次。程序员的痛苦莫过于此！！！
统计基础数据共计 17469 条 数据！文件大小约为 1.96 M !
现在开始制作数据表：(先修改 fileR.py)
import codecs def makeSql():
file_path = "../../testFile/frc/words_sql.txt"
f = codecs.open(file_path, "w+", 'utf-8')
f.write("")
f.close() fw = open("../../testFile/frc/word.txt", mode='r', encoding='utf-8')
tmp = fw.readlines() num = tmp.__len__() for i in range(0,num):
group = tmp[i].split("\t")
group[0] = "'" + group[0] + "'"
group[3] = "'" + group[3][0:group[3].__len__()-1] + "'"
f = codecs.open(file_path, "a+", 'utf-8')
f.write("Insert into words values ("+group[0]+","+group[1]+",'"+group[2]+"',"+group[3]+",'"+group[4]+"');"+"\n")
f.close() makeSql()
fileR.py
执行并按照之前的方法导入数据，这里博主因为使用电脑管家清理了一下C盘，然后 Navicat就崩掉了，真的崩了（建立不了查询了，这个之后有解决方法的话，我再写一期博客吧！）！所以，不搞虚的，直接用文本导入了！
建立 keywords 表（或视图）的方法同上上期的博客，那样获取每一个热词的数量！
CREATE TABLE keywords
AS
(
SELECT
word AS word,
SUM(num) AS num
FROM
words
GROUP BY word
ORDER BY num
DESC
)
CreateKeywordsTable.sql
哈哈哈哈！热词频数过万了呢！希望我的电脑还能撑住，继续爬！（但是现在已经2点了，先定个2个小时的闹钟，拓扑数据让它自己爬着）
对于 WebConnector 类，我要着重说一下，我本次爬取将此代码注释掉了：
# 这句话处理以后，就将带有 “年”、“月”、“日” 字眼的语句以及之后的语句全部清除掉了，当时是旨在消除不必要的解释部分，但现在看来没必要！多多益善嘛！
tpl = StrSpecialDealer.ut_date(tpl)
早上醒来发现大问题——电脑自己休眠了，唉~希望自己能够吃一堑长一智吧！
在电脑熬夜干爬虫的时候尽力将休眠关闭，在设置中如下：
拓扑数据也完成了，大约又历时 5 个小时，关键是在电脑爬虫时我还不能用电脑干其他的（尤其是截图软件，运行的话，爬虫程序一准给你崩停）
终于有完整数据了，现在我们开始数据处理！
根据不同分类将数据汇总和数据处理了（也就是说剩余没有Python的事情了），至此热词分类完毕。
2、热词目录生成
我们需要展示每一个分类的前10个数据，以此做成第一个页面。
可以制作新的视图，也可以直接写大长 Sql 语句，我比较懒，就按长语句来了
package com.servlet; import java.io.IOException;
import java.sql.SQLException;
import java.util.List; import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; import org.json.JSONArray;
import org.json.JSONObject; import com.dblink.basic.utils.SqlUtils;
import com.dblink.basic.utils.sqlKind.MySql_s;
import com.dblink.basic.utils.user.UserInfo;
import com.dblink.bean.BeanGroup;
import com.dblink.sql.DBLink; @SuppressWarnings("unused")
public class ServletForMoreInfo extends HttpServlet{
/**
*
*/
private static final long serialVersionUID = 1L;
//----------------------------------------------------------------------//
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException
{
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("application/json");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache"); String kind = request.getParameter("kind"); JSONArray jsonArray = new JSONArray(); JSONObject jsonObj = new JSONObject(); DBLink dbLink = new DBLink(new SqlUtils(new MySql_s("rc"),new UserInfo("root","123456")));
BeanGroup bg = null;
try {
bg = dbLink.getSelect("Select word As word , SUM(num) As num From ( Select * From words Where kind = '"+kind+"' ) Group By word Order By num DESC Limit 0,10 ").beans; int leng = bg.size(); jsonObj.put("Length",leng); jsonArray.put(jsonObj); for(int i=0;i<leng;++i)
{
JSONObject jsonObject = new JSONObject();
jsonObject.put("word",bg.get(i).get(0));
jsonObject.put("num",bg.get(i).get(1));
jsonArray.put(jsonObject);
}
} catch (SQLException e) {
// Do Nothing ...
}
dbLink.free(); ServletOutputStream os = response.getOutputStream();
os.write(jsonArray.toString().getBytes());
os.flush();
os.close();
}
//---------------------------------------------------------------------------------//
}
ServletForMoreInfo.java
如果你建立了对应 10 个分类的视图，你可以添加 Servlet 如下：（否则将视图名称替换成建立视图的Select语句）
package com.servlet; import java.io.IOException;
import java.sql.SQLException;
import java.util.List; import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;

import org.json.JSONObject; import com.dblink.basic.utils.SqlUtils;
import com.dblink.basic.utils.sqlKind.MySql_s;
import com.dblink.basic.utils.user.UserInfo;
import com.dblink.bean.BeanGroup;
import com.dblink.sql.DBLink; @SuppressWarnings("unused")
public class ServletForKindKeyWords extends HttpServlet{
/**

//----------------------------------------------------------------------//
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException
{
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("application/json");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache"); String table = request.getParameter("table");
String sql_rest = request.getParameter("sql"); JSONArray jsonArray = new JSONArray(); JSONObject jsonObj = new JSONObject(); DBLink dbLink = new DBLink(new SqlUtils(new MySql_s("rc"),new UserInfo("root","123456")));
BeanGroup bg = null;
try {
bg = dbLink.getSelect("Select * From "+table+" "+sql_rest).beans; int leng = bg.size(); int maxSize = dbLink.getSelect("Select * From "+table+" ").beans.size(); int page = maxSize%leng==0?(maxSize/30):(maxSize/30)+1; jsonObj.put("Length",leng);
jsonObj.put("MaxSize",maxSize);
jsonObj.put("Page",page); jsonArray.put(jsonObj); for(int i=0;i<leng;++i)
{
JSONObject jsonObject = new JSONObject();
jsonObject.put("word",bg.get(i).get(0));
jsonObject.put("num",bg.get(i).get(1));
jsonObject.put("exp",bg.get(i).get(2));
jsonArray.put(jsonObject);
}
} catch (SQLException e) {
// Do Nothing ...
}
dbLink.free(); ServletOutputStream os = response.getOutputStream();
os.write(jsonArray.toString().getBytes());
os.flush();
os.close();
}
//---------------------------------------------------------------------------------//
}
ServletForKindKeyWords.java
然后制作 js 部分：
先显示分类，然后利用套装形式进行数据载入：
如果点击 获取本类更多热词，就可以跳转至本类页面！
Like this:
附加新 js 代码：
