Question

JNLP规范说，可选地，JNLP文件本身可以通过将其包含在JNLP应用程序的主jar（它本身必须签名）中进行签名。有谁知道maven-webstart-plugin是否可以这样做？

Answer 1

基于MWEBSTART-176，这看起来像是已经请求但尚未实现的功能。

Answer 2

JNLP签名（自动生成APPLICATION.JNLP或APPLICATION_TEMPLATE.JNLP）可以通过组合多个maven插件来完成。通常，webstart-maven-plugin完成整个工作，包括在maven模块中打包工件（例如zip文件）。进行JNLP签名的关键是将此任务分为几个步骤：

A）APPLICATION.JNLP生成：

生成jnlp并签名所有库（包括清单条目使用webstart-maven-plugin更新到目录/ target / jnlp
copy＆amp;从/ target / jnlp目录重命名jnlp文件 target / jnlp / main.jar / JNLP-INF / APPLICATION.JNLP with truezip-行家-插件
在target / jnlp / main.jar中重复签署main.jar文件行家-的jarsigner-插件
package / target / jnlp目录到工件，例如同 maven-war-plugin或maven-assembly-plugin

B）用于APPLICATION_TEMPLATE.JNLP生成（第1点和第2点与前面的步骤不同）：

同时生成：jnlp，APPLICATION_TEMPLATE.JNLP并全部签名库（包括清单条目更新）到目录 / target / jnlp with webstart-maven-plugin
从中移动APPLICATION_TEMPLATE.JNLP文件 /target/jnlp/APPLICATION_TEMPLATE.JNLP to target / jnlp / main.jar / JNLP-INF / APPLICATION_TEMPLATE.JNLP with truezip-maven-plugin
使用maven-jarsigner-plugin在/ target / jnlp / main.jar中重复签署main.jar文件
package / target / jnlp目录到工件，例如同 maven-war-plugin或maven-assembly-plugin

注1：main.jar文件被签名两次（在步骤1中）和3）），这与通过maven-jarsigner-plugin在步骤3）中仅对所有jar进行一次签名进行比较是开销。但我们需要这样做，因为webstart-maven-plugin只有配置的签名才能更新清单文件（带有权限标题）。

注意2：当您的webstart应用程序具有许多不同的构建配置文件时，此方法非常有效，因为APPLICATION.JNLP或APPLICATION_TEMPLATE.JNLP是根据您的配置文件自动生成的。

注3：开发和测试这种方法需要一天半的时间，希望它能让你的生活更轻松;）

下面是两种类型的JNLP签名的一些pom.xml部分。

A）APPLICATION.JNLP生成：

maven-webstart-plugin可以签署JNLP文件本身吗？
