本來是說今天、昨天要寫一篇完整實現的，然后今天這一篇就去寫演示類的博客的！但是又怕自己查起來不方便，還是分開寫吧！
按照昨天的進度我們就只剩下 熱詞關系圖 和 報告生成 兩部分需求了，今天晚上努努力吧！
1、使用 ECharts 接口實現關系圖。
本來想用之前那個模板來實現熱詞關系圖的，但是發現數據量大了以后，完全 js 承受不住,不過，難得也封裝了代碼，你們可以簡單看一下：
com.runtask 包：

(數據量過大警告！！！)
現在要找到一個能夠加載大量數據的關系圖......才怪！我仔細分析了一下，根本不是這么回事兒！100項數據都能加載出來，那么幾項數據怎么可能會加載不上？原因到底處在了哪里呢？其實吧，就算數據划分的問題，理想狀態下，如果一個詞僅僅能夠被歸為一個類那么，就可以生成我想的那樣的 樹形結構圖 （如果導入出來應該是中心點為樹根的星雲圖）。問題就是詞語划分沒有規定上的那么嚴格，這就讓我們的關系圖較為復雜，難以生成！那么怎么辦？樹形結構是怎樣建立呢？建立一個 Node 結點，然后去找 它 的根結點 ，這樣就繪制了一個分支，也就是說 在根節點的基礎之上，我們每每建立一個新節點，就會建立一個與之對應的分支，也就是說 新建分支數 = 新建結點數。在這種情況下，我們 結點的建立 和 分支的建立是同步進行的，就像上方封裝的 Java 代碼一樣！我們要的圖的結構並不是樹形結構，而是 圖！所以我們要結點建立和分支建立分步進行！先結點，后分支！
建立思路：在中心結點的基礎上，添加10個分類的結點，並建立相關分支（這部分是樹形結構）。構建完成基礎部分以后，開始以 keywords 表為中心建立結點。最后，以 10 類視圖為中心建立關聯。
如下圖：
修改以后的 LockedModel Java 類：

2、Word報告生成
對於 Java 生成 Doc 文檔部分，我早在之前做河北填報項目的時候做過了，想了解更多的話，自己去查找 POI 的相關知識，本篇博客不是來講 POI 怎么用的，請博友勿問，自己去網上找相關的代碼資料，我僅提供檢索式：“Java POI 寫 word ”
將 POI 相關 Jar 包 導入 lib 文件夾：
因為是去年10月多做項目來着，所以是那個時候的 Jar 包，也不知道更新沒有。
為了防止因為MySql的原因，出現 SQLNonTransientConnectionException ，提前先設置好 最大連接數目：
//查看最大連接數目 show variables like 'max_connections'; //修改最大連接數目為1000 set GLOBAL max_connections=1000;
以上兩句代碼，需要以 Shell 模式運行 MySql 輸入。
其次，需要我們整理構建順序，我們寫數據是一類一類寫的，而我們可以在同步構建 Word 的目錄結構和具體詞頻解釋！（其中我寫了鏈接跳轉，但因為老師沒有這方面的需求。於是我又把那部分代碼注釋掉了）
然后，我來分享我自己在項目制作過程中 POI 用到的知識點。
添加頁碼（參考博客：https://www.iteye.com/blog/53873039oycg-2149884）
添加標題（參考博客：https://blog.csdn.net/qq_28796037/article/details/99168627）
具體報告生成部分的代碼不再給予（用到了多方博客的源碼，免於侵權）
1 package com.servlet; 2 3 import java.io.IOException; 4 5 import javax.servlet.ServletException; 6 import javax.servlet.http.HttpServlet; 7 import javax.servlet.http.HttpServletRequest; 8 import javax.servlet.http.HttpServletResponse; 9 10 import com.docmake.FinalFunction; 11 12 13 public class ServletForMakeFiles extends HttpServlet{ 14 /** 15 * 16 */ 17 private static final long serialVersionUID = 1L; 18 19 //----------------------------------------------------------------------// 20 public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException 21 { 22 request.setCharacterEncoding("utf-8"); 23 response.setCharacterEncoding("utf-8"); 24 response.setContentType("application/json"); 25 response.setHeader("Cache-Control", "no-cache"); 26 27 String filepath = request.getParameter("filepath"); 28 29 FinalFunction ff = new FinalFunction(filepath); 30 31 ff.make(); 32 33 ff.close(); 34 } 35 //---------------------------------------------------------------------------------// 36 }
效果演示：
可以看到新添加了 “創建Doc文檔” 按鈕！
難得能在 10 天時間以內，做完這個項目啊！
