Eclipse Rest示例的问题

标签： java rest

我对编写剩余应用程序不熟悉，并尝试了十多种不同的应用程序，但由于某种原因而无法运行它们。我正在尝试的最新示例来自Crunchify，并且在没有任何错误的情况下进行编译，但是在Tomcat中加载失败。

以下是详细信息：

我知道之前曾有人问过这个错误，但是没有一个答案对我有用。 环境是：Eclipse 2018-09，Java 10和Tomcat 9，该示例来自Crunchify，我严格按照步骤进行操作。 我打开了“自动编译”功能，并且Java代码构建良好。当我尝试启动应用程序时，Tomcat产生了以下错误：

下面是构建路径的图像（Eclipse不允许仅复制列表，因此必须对其进行屏幕截图。

让我知道是否还有其他需要。 谢谢， 戴夫
