Question

我得到了一个安静的应用程序，由于某种原因 - 我无法使用Java类从新包中执行方法导致Tomcat显示404错误。我的老班没有错误。

以下是旧类（ManageService）和新类（NewsFeedService）

的比较截图

这些是网址：

工作一次： http://localhost:8180/ChatRestNoSQLMaven/rest/MessageService/getDialog/8bea7f62-8bff-486c-a2bf-a2f989d0c9a8/c95aaad7-7ceb-408d-86a1-15089c399430

失败的一个：

http://localhost:8180/ChatRestNoSQLMaven/rest/NewsFeedService/hello

HTTP状态404 - 未找到

输入状态报告

消息未找到

说明请求的资源不可用。

我让Maven干净并安装命令，卸载/安装Eclipse Tomcat服务器，制作Project - ＆gt;全部构建，但没有结果。可能是什么原因？

Answer 1

     <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>rest.account,rest.message,rest.friends</param-value>
     </init-param>

您的param-value文字内容还应列出rest.newsfeed包。

Answer 2

您可以修改<param-value>以查找您在rest包中定义的所有类，这意味着您可以重新设置：

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>rest.account,rest.message,rest.friends</param-value>
</init-param>

为此：

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>rest</param-value>
</init-param>

使用此配置，您可以避免将每个新包添加到<param-value>

Answer 3

请在eclipse服务器配置和server.xml文件中检查您的端口。请检查端口号是否相同

Eclispe Tomcat显示一个网址，并显示另一个网址错误
