首先點(diǎn)擊電腦的開始，找到QLServer配置管理器，將SQLServer網(wǎng)絡(luò)配置中的SQLEXPRESS的協(xié)議如下圖中的三個(gè)服務(wù)改為啟用，然后點(diǎn)擊TCPIP協(xié)議，修改動(dòng)態(tài)端口為1433，重啟服務(wù)器才能生效，首先建立一個(gè)java項(xiàng)目，命名為TestDB然后右鍵點(diǎn)擊TestDB選擇buildpath然后找到AddExternalJARs，找到下載的sqljdbc的包，打開即可，然后項(xiàng)目的referencedlibraries目錄下能看到導(dǎo)入的包，新建一個(gè)包database包中再建立TestConect執(zhí)行以下代碼，代碼執(zhí)行結(jié)果和數(shù)據(jù)庫(kù)中查詢的結(jié)果一樣。
