星期三

　　【本博客的代码如若要使用，请在下方评论区留言，之后再用（就是跟我说一声）】

　　所有相关跳转：

　　a.【简单准备】

　　b.【云图制作+数据导入】

　　c.【拓扑数据】

　　d.【数据修复】

　　e.【解释修复+热词引用】

　　 f.【JSP演示+页面跳转】

　　g.【热词分类+目录生成】

　　h.【热词关系图+报告生成】（本期博客）

　　i . 【App制作】

　　j . 【安全性改造】

　　本来是说今天、昨天要写一篇完整实现的，然后今天这一篇就去写演示类的博客的！但是又怕自己查起来不方便，还是分开写吧！

　　按照昨天的进度我们就只剩下热词关系图和报告生成两部分需求了，今天晚上努努力吧！

　　1、使用 ECharts 接口实现关系图。

　　　　本来想用之前那个模板来实现热词关系图的，但是发现数据量大了以后，完全 js 承受不住,不过，难得也封装了代码，你们可以简单看一下：

　　　　com.runtask 包：

 package com.runtask;
 
 import org.json.JSONObject;
 
 public class MetBuilder {
     /*获取新节点*/
     public static JSONObject getPointData(String name,String des,int symbolSize,String color){
         LockedModel.dataSize += 1;
         JSONObject jsonObject = new JSONObject();
         jsonObject.put("name",name);
         jsonObject.put("des",des);
         jsonObject.put("symbolSize",symbolSize);
         JSONObject job1 = new JSONObject();
         JSONObject job2 = new JSONObject();
         job1.put("color",color);
         job2.put("normal",job1);
         jsonObject.put("itemStyle",job2);
         return jsonObject;
     }
     public static JSONObject getPointData(String name,String des,int symbolSize){
         LockedModel.dataSize += 1;
         JSONObject jsonObject = new JSONObject();
         jsonObject.put("name",name);
         jsonObject.put("des",des);
         jsonObject.put("symbolSize",symbolSize);
         return jsonObject;
     }
     /*获取新线路*/
     public static JSONObject getLineData(String source,String target,String name,String des){
         LockedModel.linkSize += 1;
         JSONObject jsonObject = new JSONObject();
         jsonObject.put("name",name);

　　　　(数据量过大警告！！！)

　　　　现在要找到一个能够加载大量数据的关系图......才怪！我仔细分析了一下，根本不是这么回事儿！100项数据都能加载出来，那么几项数据怎么可能会加载不上？原因到底处在了哪里呢？其实吧，就算数据划分的问题，理想状态下，如果一个词仅仅能够被归为一个类那么，就可以生成我想的那样的树形结构图（如果导入出来应该是中心点为树根的星云图）。问题就是词语划分没有规定上的那么严格，这就让我们的关系图较为复杂，难以生成！那么怎么办？树形结构是怎样建立呢？建立一个 Node 结点，然后去找它的根结点，这样就绘制了一个分支，也就是说在根节点的基础之上，我们每每建立一个新节点，就会建立一个与之对应的分支，也就是说新建分支数 = 新建结点数。在这种情况下，我们结点的建立和分支的建立是同步进行的，就像上方封装的 Java 代码一样！我们要的图的结构并不是树形结构，而是图！所以我们要结点建立和分支建立分步进行！先结点，后分支！

　　　　建立思路：在中心结点的基础上，添加10个分类的结点，并建立相关分支（这部分是树形结构）。构建完成基础部分以后，开始以 keywords 表为中心建立结点。最后，以 10 类视图为中心建立关联。

　　2、Word报告生成

　　　　对于 Java 生成 Doc 文档部分，我早在之前做河北填报项目的时候做过了，想了解更多的话，自己去查找 POI 的相关知识，本篇博客不是来讲 POI 怎么用的，请博友勿问，自己去网上找相关的代码资料，我仅提供检索式：“Java POI 写 word ”

　　　　将 POI 相关 Jar 包导入 lib 文件夹：

　　　　因为是去年10月多做项目来着，所以是那个时候的 Jar 包，也不知道更新没有。

　　　　为了防止因为MySql的原因，出现 SQLNonTransientConnectionException ，提前先设置好最大连接数目：

//查看最大连接数目
show variables like 'max_connections';
//修改最大连接数目为1000
set GLOBAL max_connections=1000;

　　　　以上两句代码，需要以 Shell 模式运行 MySql 输入。

　　　　其次，需要我们整理构建顺序，我们写数据是一类一类写的，而我们可以在同步构建 Word 的目录结构和具体词频解释！（其中我写了链接跳转，但因为老师没有这方面的需求。于是我又把那部分代码注释掉了）

　　　　然后，我来分享我自己在项目制作过程中 POI 用到的知识点。

　　　　添加页码（参考博客：https://www.iteye.com/blog/53873039oycg-2149884）

　　　　添加标题（参考博客：https://blog.csdn.net/qq_28796037/article/details/99168627）

　　　　具体报告生成部分的代码不再给予（用到了多方博客的源码，免于侵权）

 package com.servlet;
 
 import java.io.IOException;
 
 import javax.servlet.ServletException;
 import javax.servlet.http.HttpServlet;

 public class ServletForMakeFiles 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");
 
         String filepath = request.getParameter("filepath");
 
         FinalFunction ff = new FinalFunction(filepath);
 
         ff.make();
 
         ff.close();
     }
     //---------------------------------------------------------------------------------//
 }

ServletForMakeFiles.java

　　　　效果演示：

　　　　可以看到新添加了 “创建Doc文档” 按钮！

　　　　难得能在 10 天时间以内，做完这个项目啊！
