把Spring boot jar作为Windows服务运行

把Spring boot jar作为Windows服务运行

当你用Spring boot时，通过Java -jar就可以启动，但你不能每次开机都这样执行一遍吧？特别是当你把jar包发布给客户的时候，你总不能要求客户每次开机后都手动执行启动。所以，最好的方式就是作为服务，随机器开机启动。

Java Service Wrapper

本文就讲一讲如何把Spring boot做成服务。

笔者最先研究了JavaService，下载地址为：http://forge.ow2.org/projects/javaservice/，按照文档即可配置，比较简单，但是在执行.bat脚本文件的时候需要具有管理员权限才能安装服务，考虑到客户可能存在较难获取管理员权限的情况，遂放弃。

考虑使用Java Service Wrapper，Java Service Wrapper就轻松而简单的为我们解决了这些问题。"Java Service Wrapper"顾名思义，将我们的Java程序包装成系统服务，这样就可以随着系统的运行而自动运行，当然Java Service Wrapper(下面简称Wrapper)的功能绝不仅于此。

以下是官方给出的一些Wrapper的优点：

(1) 使用我们的产品无须在你的程序中添加任何额外的代码。
        (2) 当你的程序或JVM出现问题时会自动响应事先定制的策略。
        (3) 当出现问题时会及时进行通知。
        (4) 完善的日志记录功能可以更好为您提供支持。
        (5) 在不同的系统上你可以指定一个标准的流程相同流程，也就是说相同的程序可以不必修改即运行于不同系统。
        (6) 可以将你的应用安装成windows或unix的服务或守护进程。

Java Service Wrapper下载

下载地址为 https://wrapper.tanukisoftware.com/doc/english/download.jsp，最新版本为3.5.34，根据自己的情况选择自己对应的操作系统和位数。

通过下载页面我们可以看到Wrapper几乎支持所有的系统环境，Windows32位社区版是免费使用的，Windows 64位没有免费版本。我们这里主要讲Windows系统。

Java Service Wrapper主要目录

解压后的文件目录如下图：

这些目录并不是你做服务必须的，有些可以不不要。各目录的主要作用如下：

1. bin目录下主要的文件有：InstallTestWrapper-NT.bat、TestWrapper.bat、UninstallTestWrapper-NT.bat、wrapper.exe

2. conf目录下主要文件有：wrapper.conf

3. lib目录下主要文件有：wrapper.dll、wrapper.jar、wrappertest.jar

4. logs目录下主要文件有：wrapper.log(可以配置改名的)

Java Service Wrapper配置

然后，将你的jar包放入lib目录，接下来是对conf/wrapper.conf进行修改，这是最重要的修改，直接关系到你的服务是否能创建成功。内容如下：

#encoding=UTF-8

# Configuration files must begin with a line specifying the encoding

# of the the file.
