在 GWT 中设置 remoteLoggingServlet [英] Setup a remoteLoggingServlet in GWT

问题描述

来自 http://code.google.com/intl/es-ES/webtoolkit/doc/latest/DevGuideLogging.html 在远程日志记录部分下它说你需要

From http://code.google.com/intl/es-ES/webtoolkit/doc/latest/DevGuideLogging.html under the remote logging section it says that you need to

您还需要为 remoteLoggingServlet 提供服务.

You will also need to serve the remoteLoggingServlet.

我想使用远程日志记录功能，但找不到如何执行此步骤的示例.

I would like to use the remote logging feature but I cannot find an example of how to do this step.

我在我的 .gwt.xml 中设置了以下内容

I have setup the following in my .gwt.xml

<!-- Logging configuration -->
  <inherits name="com.google.gwt.logging.Logging"/>
  <set-property name="gwt.logging.logLevel" value="INFO"/>
  <set-property name="gwt.logging.enabled" value="TRUE"/>
  <set-property name="gwt.logging.simpleRemoteHandler" value="ENABLED" />  
  <set-property name="gwt.logging.developmentModeHandler" value="ENABLED" />  
  <set-property name="gwt.logging.systemHandler" value="ENABLED" />
  <set-property name="gwt.logging.popupHandler" value="DISABLED" />
  <set-property name="gwt.logging.consoleHandler" value="DISABLED"/> 
  <set-property name="gwt.logging.firebugHandler" value="DISABLED" />   

日志出现在 std.out 控制台和开发模式控制台中，但使用远程日志记录时出现以下错误

The logs appear in the std.out console and the dev mode console but with the remote logging I get the following error

严重:远程日志记录失败:com.google.gwt.user.client.rpc.StatusCodeException: 404

推荐答案

你应该在你的 web.xml 中定义 remote_logging servlet:

You should define remote_logging servlet in your web.xml:

<!-- remote logging -->
<servlet>
    <servlet-name>remoteLogging</servlet-name>
    <servlet-class>com.google.gwt.logging.server.RemoteLoggingServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>remoteLogging</servlet-name>
    <url-pattern>/your-gwt-module-name/remote_logging</url-pattern>
</servlet-mapping>
