把Spring boot jar作為Windows服務運行

當你用Spring boot時，通過Java -jar就可以啟動，但你不能每次開機都這樣執行一遍吧？特別是當你把jar包發布給客戶的時候，你總不能要求客戶每次開機后都手動執行啟動。所以，最好的方式就是作為服務，隨機器開機啟動。

Java Service Wrapper

本文就講一講如何把Spring boot做成服務。

筆者最先研究了JavaService，下載地址為：http://forge.ow2.org/projects/javaservice/，按照文檔即可配置，比較簡單，但是在執行.bat腳本文件的時候需要具有管理員權限才能安裝服務，考慮到客戶可能存在較難獲取管理員權限的情況，遂放棄。

考慮使用Java Service Wrapper，Java Service Wrapper就輕松而簡單的為我們解決了這些問題。"Java Service Wrapper"顧名思義，將我們的Java程序包裝成系統服務，這樣就可以隨著系統的運行而自動運行，當然Java Service Wrapper(下面簡稱Wrapper)的功能絕不僅于此。

??????? 以下是官方給出的一些Wrapper的優點：

??????? (1) 使用我們的產品無須在你的程序中添加任何額外的代碼。
??????? (2) 當你的程序或JVM出現問題時會自動響應事先定制的策略。
??????? (3) 當出現問題時會及時進行通知。
??????? (4) 完善的日志記錄功能可以更好為您提供支持。
??????? (5) 在不同的系統上你可以指定一個標準的流程相同流程，也就是說相同的程序可以不必修改即運行于不同系統。
??????? (6) 可以將你的應用安裝成windows或unix的服務或守護進程。

Java Service Wrapper下載

下載地址為 https://wrapper.tanukisoftware.com/doc/english/download.jsp，最新版本為3.5.34，根據自己的情況選擇自己對應的操作系統和位數。

通過下載頁面我們可以看到Wrapper幾乎支持所有的系統環境，Windows32位社區版是免費使用的，Windows 64位沒有免費版本。我們這里主要講Windows系統。

Java Service Wrapper主要目錄

解壓后的文件目錄如下圖：

這些目錄并不是你做服務必須的，有些可以不不要。各目錄的主要作用如下：

?

1.??????bin目錄下主要的文件有：InstallTestWrapper-NT.bat、TestWrapper.bat、UninstallTestWrapper-NT.bat、wrapper.exe

2.??????conf目錄下主要文件有：wrapper.conf

3.??????lib目錄下主要文件有：wrapper.dll、wrapper.jar、wrappertest.jar

4.??????logs目錄下主要文件有：wrapper.log(可以配置改名的)

Java Service Wrapper配置

然后，將你的jar包放入lib目錄，接下來是對conf/wrapper.conf進行修改，這是最重要的修改，直接關系到你的服務是否能創建成功。內容如下：

# Configuration files must begin with a line specifying the encoding

#? of the the file.
