java - URL 模式不适用于 localhost url(没有 maven 的 jersey)

Question

这是我的 web.xml。我已将 url 模式设置为 rest.iam 使用 jersey 构建 Web 服务。但是在 tomcat 6 中运行时，出现 404 错误。

Web.xml

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

                     com.sun.jersey.spi.container.servlet.ServletContainer
                </servlet-class>

     <init-param>

      <param-name>com.sun.jersey.config.property.packages</param-name>
      <param-value>com.snapshothealthapp1.controller</param-value>

    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
        <servlet-name>jersey-serlvet</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
</web-app>

我的网页在此图像中，我们可以看到它只是使用 localhost urland 调用 Rest，但它收到了 404 异常。

通过在我的程序中添加以下代码解决了该问题

return Response.status(201).entity(result).build();

并重新检查此处指定的已安装 jar
