Question

我正在尝试创建基于Jersey 2的项目。该项目将公开一个返回json的服务。但是在启动应用程序时，我仍然没有找到404错误，我无法找出错误。

因为我使用Mave，所以这是我的pom：

twbs:bootstrap

这是我的web.xml：

Answer 1

您的依赖项为provided。这就是说Tomcat有罐子，但它没有。只需删除<scope>provided</scope>

即可

你也可以取出这些（它们被jersey-container-servlet拉入

）

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0.1</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-server</artifactId>
    <version>2.19</version>
</dependency>

使用Jersy 2.19，我找不到有什么问题，我总是有404
