使用Windows Service Wrapper快速创建一个Windows Service

前言

今天介绍一个小工具的使用。我们都知道Windows Service是一种特殊的应用程序，它的好处是可以一直在后台运行，相对来说，比较适合一些需要一直运行同时不需要过多用户干预的应用程序，这一类我们称之为“服务”吧

编写Windows Service其实是不难的，尤其是如果有Visual Studio的话。但是仍然是有不少童鞋觉得略显繁琐，同时，如果有一些其他的程序，我们只拿到一个exe，或者一个bat，但又想让他象服务一样运行，怎么办呢

答案就是可以使用如下的一个工具，它的名称就叫：Windows Service Wrapper，简称WSW。

wsw的基本使用

一般的使用步骤是：

1. 下载wsw的最新版本，放在任意的位置，修改成你想要的任何名字

2.编写一个同名的xml文件

3.使用Install命令进行安装

4.如果想要卸载，则使用Uninstall命令

This project creates a wrapper executable that can be used to host any executable as an Windows service.

Download

The binaries are available here for download.

Usage

During your development...

Take winsw.exe from the distribution, and rename it to your taste (such as myapp.exe)
Write myapp.xml (see Configuration Syntax for more details)
Place those two files side by side when you deploy your application, because that's how winsw.exe discovers its configuration.

At runtime...

To install a service, run myapp.exe install
To start a service, run myapp.exe start
To stop a service, run myapp.exe stop
To restart a service, run myapp.exe restart
To uninstall a service, run myapp.exe uninstall

When there's a problem, these commands also report an error message to stderr. On a successful completion, these commands do no produce any output and exit with 0.

In addition, you can also run myapp.exe status to have it print out the current status of the service to stdout. Again, any error encountered during the processing would cause output to be reported to stderr.

All these commands use the same set of exit code to indicate its result.

Deferred File Operations

To support self updating services, winsw offers a mechanism to perform file operations before a service start up. This is often necessary because Windows prevents files from overwritten while it's in use.

To perform file operations, write a text file (in the UTF-8 encoding) at myapp.copies (that is, it's in the same directory asmyapp.xml but with a different file extension), and for each operation add one line:
