背景：我們一直在重構，調整架構，但是一直不知道我們做的效果如何，也沒有辦法量化，所以需要引入一個工具和標準來量化我們的工作。

簡介：sonarqube是一個開源的，程式碼質量檢測的工具，我們可以使用它來檢測我們的程式碼。

如何安裝：

2.將安裝包解壓到指定目錄

進入以下目錄：

/Users/xiepengchong/opensource/sonarqube-5.6.3/bin/macosx-universal-64

執行：

./sonar.sh start

即可啟動該功能。

如何使用：

下載sonarqube runner

配置sonar－runner的環境變數

然後進入我們需要執行檢查的工程下面。

新建一個名字是 sonar-project.properties的檔案。（內容如下）

sonar.projectKey=UCarNew
sonar.projectName=UCarNew
sonar.projectVersion=5.0
# Path to the parent source code directory.
# Path is relative to the sonar-project.properties file. Replace "\" by "/" on Windows.
# Since SonarQube 4.2, this property is optional if sonar.modules is set.
 
# If not set, SonarQube starts looking for source code from the directory containing
# the sonar-project.properties file.
sonar.sources=./
# Encoding of the source code
sonar.sourceEncoding=UTF-8
# Additional parameters
sonar.my.property=value

最後直接執行：

sonar-runner

就可以進行檢查了，

如何檢視結果：

檢查有如下日誌：

開啟網址，可以看到如下頁面。

通過切換不同的tab，可以檢視詳細資訊。

最後說一下如何提高我們的程式碼質量：

1.恰當的使用if，switch等判斷邏輯的使用。因為每一個邏輯的判斷都是一個複雜度的引入，

2.減少重複的程式碼，每一段重複的程式碼將會造成維護工作量的double，

3.減少每個檔案的大小，檔案的大小與維護成本成指數級別增加。

PS:時隔幾天之後，啟動的時候，突然不能用了。

在這個路徑下，啟動，就解決了，真是很奇怪，我以為路徑沒關係呢。

最近(2017年12.4日)再次未新公司的程式碼做檢查的時候,在linux伺服器上搭建了一個環境,(sonarqube-6.7.zip)

發現竟然報錯了
