集成druid數據源【JWordPress前臺項目實戰】
DRUID是阿裏巴巴開源平臺上一個數據庫連接池實現，它結合了C3P0、DBCP、PROXOOL等DB池的優點，同時加入了日誌監控，可以很好的監控DB池連接和SQL的執行情況，下面我們來講講springboot如何繼承druid連接池
代碼
pom.xml添加相應的jar
<!–alibaba 數據庫連接池 druid 配置 –>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.28</version></dependency>

測試
啟動應用，然後訪問http://127.0.0.1:8090/druid/index.html
實戰項目介紹
項目介紹：
為了滿足Java新手朋友課程要求，我特出此教程，由於時間倉促的問題，代碼寫得不好之處的地方還請多多包涵。
目標如下
優化wordpress效率低下的問題（目前博主文章數量大概10萬+）
讓群裏面初級Java朋友們更快上手springboot應用
