jetty部署war包

與tomcat類似，直接拷貝war到webapps目錄即可，不同的是解壓文件不會存放到webapps下。

需要做一些額外配置，才能找到正確解壓目錄

Q: How to change the extracted directory?

A: You have few choices.

1) Specify your own java.io.tmpdir java system property location for jetty to use.

    $ java -Djava.io.tmpdir=/path/to/my/new/temp/ -jar start.jar

2) Create a "work" directory under the ${jetty.home} path (whereever that is).

    That will cause Jetty to use that work directory instead of whatever the java.io.tmpdir property is set to.

3) Specify the tempDir attribute on the WebAppProvider deployments.

    Only valid for war file deployment scenarios, NOT valid for context based deployment.

    If you have etc/jetty-webapps.xml in your start.ini you have war file deployments enabled.

    Edit the ${jetty.home}/etc/jetty-webapps.xml file and add 1 more attribute on the WebAppProvider.

    <Set name="tempDir">/path/to/my/preferred/temp/dir/for/all/webapps</Set>

4) Set the tempDirectory attribute on the WebAppContext with context based deployments.

    NOT valid for war file deployment scenarios.

    If you have etc/jetty-context.xml in your start.ini you have context based deployments enabled.

    Edit the ${jetty.home}/contexts/myapp.xml and add the tempDirectory attribute on the WebAppContext.

    <Set name="tempDirectory">/path/to/my/preferred/temp/dir/for/this/context</Set>
