我遵循本教程： https://jersey.java.net/documentation/latest/getting-started.html 这是我的pom.xml文件：

我遇到过这个错误：

  

＆＃39; dependencies.dependency.version＆＃39;对于   org.glassfish.jersey.containers：jersey-container-grizzly2-http：jar is   丢失

帮我解决问题。

Answer 1

您需要在依赖声明中添加版本信息：

前：

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-grizzly2-http</artifactId>
    <version>2.21</version>
</dependency>

Answer 2

我删除评论：

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-moxy</artifactId>
</dependency>

然后它的工作原理。这是示例源代码中的缺陷。
