java - dropwizard 中的 Guice 依赖注入不起作用 - 它是 pom.xml 工件依赖问题吗？

Question

我想运行一个 Dropwizard（一个 REST 应用程序）。

我有一个使用旧版本 dropwizard (1.0.3) 的 pom.xml 文件，它可以工作。新版本（2.0.10）还有另一个 pom.xml 可用，但它没有运行。

这是 githut 上可用的 pom.xml（DropWizard 的 1.0.3 版本）：

https://github.com/userInterview/dropwizard-guice

只需复制 pom.xml 即可重现错误或工作版本。

这是两个 pom.xml 文件：

• 这是适用于旧 DropWizard Release (1.03) 的相应 pom.xml
