java - Jersey 1.91.x 404 错误

Question

我在发出休息请求时收到 404 错误。我的环境详细信息如下:

Jersey 1.91.1

Apache Tomcat/7.0.42

Java jdk1.7.0_80

我的 web.xml 看起来像这样

<web-app>
<display-name>Archetype Created Web Application</display-name>
<listener>
    <listener-class>com.company.gcs.zanshin.notificationengine.web.ContextStarter</listener-class>
</listener>
<servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.company.gcs.zanshin.notificationengine.web</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/operations/*</url-pattern>
</servlet-mapping>

当我启动 tomcat 时，我看到 jersey 正在加载所有正在正确加载的资源类

Java 程序

@Path("/operations")
class FileRestPoints {

    @Path("/file/upload")
    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.APPLICATION_JSON)
    public def upload(
            @FormDataParam("file") InputStream uploadedInputStream,
            @FormDataParam("file") FormDataContentDisposition fileDetail,
            @FormDataParam("notificationId") String notificationId)
    {
        FileUploader uploader = new FileUploader();

        String fileName = fileDetail.getFileName();

        def resp = uploader.upload(notificationId,fileName,uploadedInputStream)

        return toJson(resp);
    }
}

Answer 1

我通过在 url 中提供两次 operations 来解决它，例如 localhost:8080/notification/operations/operations/file/upload。这是因为在 web.xml 和 Java 类中都有关键字 operations。
