尝试在Tomcat中运行我的WebApp示例后,没有成功,我遵循this tutorial以获得在Eclipse中使用Maven运行的简单HelloWorld JAX-RS应用程序。不幸的是,当我在浏览器中执行mvn jetty:run
并打开http://localhost:8088/jersey-demo/hello/
时,我才会回来:
HTTP ERROR: 503
SERVICE_UNAVAILABLE
RequestURI=/jersey-demo/hello

在Eclipse中,转到Windows
- &gt; Preferences
- &gt; Maven
- &gt; User Settings
并确保您的settings.xml
目录下有.m2
个点。
同时检查第二个字段Local Repository
是否具有正确的存储库地址。
