在Java中设置Web服务器的最简单方法是什么？

Question

I have server daemons running on several machines. I decide to expose the internal stats of the server daemons for monitoring and statistic, using HTTP protocol.

So, what's the simplest way to do this?

• The less 3rd-party jar dependencies, the better.
• The lighter the framework is, the better.
• The less complexity, the better.

Answer 1

If the stats are a small number of fairly basic statistics, and you aren't wedded to the HTTP server concept, use JMX. I used it to instrument a daemon process and it was pretty simple. You can monitor remotely (on another computer) via an ugly, but serviceable UI.

Here's a tutorial instrumenting a web server app Probably very close to what you want.

Here's a StackOverflow link on remote monitoring

Answer 2

The lightest weight java webserver I know of is Jetty . If you use maven, you don't have to add any dependencies to your project, just add jetty as a plugin:

 <plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>maven-jetty-plugin</artifactId>
    <version>6.1.26</version>
 </plugin>

then you can just call

 mvn jetty:run

at the command line. a lot of open source projects ship with a jetty server embedded, including hadoop.
