Question

我正在尝试编写一个小的REST服务作为Java todolist应用程序。幸运的是，它在我的Windows 10环境中运行在tomcat上。不幸的是，它拒绝在我的Linux环境中运行tomcat（详见下文）。我认为Java的想法是独立于平台。捕获量在哪里？我做错了什么？

环境细节

Windows 10 Pro上的

Works

apache tomcat 8.5.4
jvm 1.8.0_101-b13
architecture amd64

Linux上的

失败 Ubuntu 14.04 LTS（4.4.0-34-generic）（在virtualbox中）

apache tomcat 8.5.4
jvm 1.8.0_101-b13
with architecture amd64

以下是我文件的链接。我很抱歉无法将其作为标记代码（markdown或html）发布。我在45分钟后放弃了。多可惜。：（

感谢您的帮助！：）

Answer 1

我会重新验证您的Linux环境。我能够在Tomcat 8.0.x和8.5.4中的Mac OS / X和Ubuntu 14.04下运行代码。我使用了javax.ws.rs.core.Application配置，因为你没有包含你的web.xml，除了它直接是你的代码。我同意@Andreas你有一些混合的库版本，但我不知道为什么你会遇到这个问题。你有没有其他任何部署到Linux Tomcat？您是否对Tomcat安装下的“lib”目录进行了任何修改？

Answer 2

pom标记javax.servlet，因此您的应用程序将使用Tomcat提供的版本。基于异常报告，Linux上的Tomcat似乎使用旧版本，其中getProperties（）方法不存在。

从docs开始，在2.0中添加了getProperties（）方法，因此Linux Tomcat显然使用旧版本。

依赖于平台的.war文件是用maven和Jersey / Jackson设置的？
