这就是我的POM和网络的样子.我已经尝试将所需的war文件复制到C:\ appache tomcat 7但没有运气.即使在日食中部署它也会给我带来同样的错误.

Answer 1

除了例外,com.sun.jersey.spi.container.servlet.ServletContainer您的类路径中似乎没有该类.

请注意,Jersey 1.x和Jersey 2.x使用不同的包名称:

• 泽西岛1.x: com.sun.jersey
• 泽西2.x: org.glassfish.jersey

所以,我理解你正在使用泽西1.x的.

泽西岛1.x的依赖性

要使用Jersey 1.x,您需要具备以下依赖性pom.xml:

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>1.19</version>
</dependency>

要阅读有关Jersey 1.x依赖项的更多信息,请查看文档.

您可以检查最新版本jersey-server artifactId的Maven仓库.

泽西岛2.x的依赖性

如果要使用Jersey 2.x,则必须将以下依赖项添加到pom.xml:

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <!-- if your container implements Servlet API older than 3.0, 
         use "jersey-container-servlet-core"  -->
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22.1</version>
</dependency>

您可以检查最新版本jersey-container-servlet artifactId的Maven仓库.

阅读文档中有关Jersey 2.x依赖项的更多信息.

UPDATE

如果可以的话,我不建议使用泽西2.x的,而不是新泽西1.x的.

为此,请使用以下内容pom.xml:
