您不必在已安装的 Web 服务器中运行 Jersey 应用程序。您可以在嵌入式服务器中运行它，这意味着使用普通方法在独立模式下运行的服务器。main
如果您使用的是 Maven，并且熟悉如何创建 Maven 原型，则可以使用原型jersey-quickstart-grizzly2
这是您通过原型项目免费获得的所有内容。

System.out.println(String.format("Jersey app started with WADL available at "

System.in.read();

pom.xml- 我添加了和我自己，以便您可以创建一个可运行的jar文件。jersey-media-json-jacksonmaven-assembly-plugin

有了以上所有，你可以从命令行到项目并做cd
mvn clean packagejava -jar target/jersey-grizzly-jar-with-dependencies.jar
，应用程序将启动。
您可以从以下位置访问它http://localhost:8080/myapp/myresource
就是这样。请注意，以上是一个普通的jar项目。因此，如果您无法遵循如何创建原型，则几乎可以将上述所有内容复制到jar项目中。
