Question

我在一个项目中使用泽西编写了一个REST web服务，它可以正常工作（eclipse）。现在我正在尝试将该Web服务移动到已经存在的项目中，但其失败的状态为404。它正在工作的项目的web.xml是：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
 <servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.javatpoint.rest</param-value>
    </init-param>
    <init-param>
       <param-name>jersey.config.server.provider.classnames</param-name>
       <param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
 </servlet-mapping>
</web-app>

现在使用此配置和“jerseyhelloworldtest”作为我的.war文件的名称，我可以使用URL http://localhost:8080/jerseyhelloworldtest/rest/files/name访问Web服务但是，当我将同一个webservice移动到另一个项目并使用该项目的.war文件名更改jerseyhelloworldtest时，它无法在那里工作。该项目的web.xml是：

现在我在这里尝试使用URL http://localhost:8080/Softwarepartwebservice/rest/files/name访问相同的Web服务，但它给出了404。需要帮助。

对不起，这是我犯的一个非常愚蠢的错误，我从来没有注意到。在更改项目时，我必须更新

中的包条目

ValueError: All shapes must be fully defined: [TensorShape([Dimension(None), Dimension(None), Dimension(None)]), TensorShape([])]

image = tf.reshape(image, tf.pack([height, width, 3]))
image = tf.reshape(image, [32,32,3])

到我的新服务类所在的包中。 com.javatpoint.rest是旧项目的包，我改为新项目。改变它使它工作。写这里，以防这可能有助于面临同样问题的人。

REST给404
