HTTP状态404请求的资源不可用jersey tomcat

Question

我无法在tomcat8服务器上启动测试应用程序。当我输入http://localhost:8080/loginservice/rest/auth时，错误消息是“HTTP Status 404-type Status Report.message：description请求的资源不可用。”起始页http://localhost:8080/工作良好。我把所有的jar文件(jersey-client、jersey-common、jersey-container-servlet、jersey-container-servlet-core、jersey-server、javax.ws.rs-api-2.0...）在WEB-INF/lib下。而loginService是由服务器部署的。

WEB-INF下的web.xml文件

我使用的是tomcat8和Jersey2.10.1。

我刚刚将web.xml文件更改为：

Answer 1

您的应用程序似乎缺少了一些必需的库，或者（因为您已经有了jercy-common.jar）类路径中已经存在的库不兼容。

因此，我想在下面的链接中指出一个完美工作（用Tomcat8测试）的示例。

泽西-HelloWorld-示例

希望这有帮助。
