Question

使用gwt logs jar我可以在我的控制台上显示日志。但是现在我想从客户端添加我的olgs文件中的日志，就像我们在服务器端使用log4j一样。所以我提到http://code.google.com/p/gwt-log/wiki/GettingStarted这个链接，但我没有看到任何客户端日志在我的日志文件中生成。

以下是我的gwt.xml文件

<inherits name="com.allen_sauer.gwt.log.gwt-log-DEBUG" />
<set-property name="log_DivLogger" value="DISABLED" />
<!-- In gwt-log-3.0.3 or later -->
<inherits name="com.allen_sauer.gwt.log.gwt-log-RemoteLogger" />
<set-configuration-property name="log_pattern" value="%d [%t] %p - %m
   %n" />

以下是我的web.xml文件

<servlet>
<servlet-name>gwt-log-remote-logger-servlet</servlet-name>
<servlet-class>com.allen_sauer.gwt.log.server.RemoteLoggerServiceImpl</servlet-class>
<!--
   The `symbolMaps` parameter specifies the server directory
    containing the GWT compiler symbol maps output, which is used
     for stack trace deobfuscation
    -->
  <init-param>
       <!-- This value assumes a GWT compile with '-deploy war/WEB-INF/deploy/' -->
      <param-name>symbolMaps</param-name>
       <!--
     Modify the param-value based on your server environment. Some web servers
    use your `war` directory as the 'current working dir', while other
    vendors will do something different. You may use trial and error. Specify the
    relative path you think should work, then check the server log after forwarding
    the first client log message to the server. If the directory cannot be found,
    gwt-log will report the full path which it tried.
  -->
  <param-value>WEB-INF/deploy/detectfiles/symbolMaps/</param-value>
  </init-param>

  <!--
    Additional or alternate directories may be specified via additional parameter
  which also begin with `symbolMaps`. This may be useful if you deploy to multiple
  server environments which use different directory structures or have a different
  notion of what the 'current working directory' is.
 --> 
 <init-param>
   <param-name>symbolMaps_2</param-name>
   <param-value>WEB-INF/deploy/detectfiles/symbolMaps/</param-value>
 </init-param>

     <!-- Optionally enable CORS (http://www.w3.org/TR/cors/)
  <init-param>
     <param-name>Access-Control-Allow-Origin</param-name>
     <param-value>http://your-applications-origin</param-value>
  </init-param> 
  -->
</servlet>

<servlet-mapping>
    <servlet-name>gwt-log-remote-logger-servlet</servlet-name>
  <url-pattern>/com.renault.detectfiles/gwt-log</url-pattern>
  </servlet-mapping>

我在clinet方面添加了log，如下所示

        Log.debug("Hi this is a debug log");

首先，确保使用附加参数-deploy war / WEB-INF / deploy /编译GWT应用程序。

其次，确保目录中存在符号映射 WEB-INF/deploy/detectfiles/symbolMaps/。我发现编译时，symbolMaps会转到目录WEB-INF/deploy/<module-name>/symbolMaps/。在这里，detectfiles看起来不像您的模块名称。因为，在url-pattern中，您已将com.renault.detectfiles指定为模块名称。

这些可能是看不到日志的可能原因。

不生成gwt日志
