Question

我已经提交了maven项目，以便在我的机器上工作，但当其他人导入该maven项目时，他们会得到例外：

模块声明一个servlet类.......，但是web.xml没有相应的映射;请将以下行添加到您的web.xml

这个类属于我的项目使用的库。我不明白是什么问题。请帮帮我。

module.gwt.xml：

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='engile'>

您需要检查扩展 RemoteService 的所有接口并声明 RemoteServiceRelativePath 注释，确保所有此类相对路径都在web.xml中映射

示例 - 在https://developers.google.com/web-toolkit/doc/latest/tutorial/RPC

中

@RemoteServiceRelativePath("stockPrices")
public interface StockPriceService extends RemoteService { 
}

会映射到

  <!-- Servlets -->
  <servlet>
    <servlet-name>stockPriceServiceImpl</servlet-name>
    <servlet-class>com.google.gwt.sample.stockwatcher.server.StockPriceServiceImpl</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>stockPriceServiceImpl</servlet-name>
    <url-pattern>/stockwatcher/stockPrices</url-pattern>
  </servlet-mapping>

模块声明了一个servlet类.......，但是web.xml没有相应的映射
