Question

我想使用deobfuscate选项配置远程日志记录服务。我知道默认情况下符号映射是在/ WEB-INF / deploy / MODULNAME / symbolMaps文件夹中生成的，GWT远程记录器实现（RemoteLoggingServiceImpl）使用StackTraceDeobfuscator，它需要symbolMaps目录才能工作。我认为RemoteLoggingServiceImpl应该自动设置symbolMaps目录的正确路径，但是在调试模式下我发现setSymbolMapsDirectory方法没有在RemoteLoggingServiceImpl上调用。要解决该问题，我使用“proxy”手动调用该方法：

public class ConfigurableRemoteLoggingServiceImpl extends RemoteLoggingServiceImpl {

@Override
public void init(final ServletConfig config) throws ServletException {
    super.init(config);

    final String symbolMapsDirectory = config.getInitParameter("symbolMapsDirectory");
    setSymbolMapsDirectory(symbolMapsDirectory);
}
}

并在web.xml中

<servlet>
        <servlet-name>remoteLogging</servlet-name>
        <servlet-class>pl.dandelite.empik.sdl.manager.server.service.ConfigurableRemoteLoggingServiceImpl</servlet-class>

        <init-param>
          <param-name>symbolMapsDirectory</param-name>
          <param-value>C:/symbolMaps</param-value>
      </init-param>
</servlet>
<servlet-mapping>
        <servlet-name>remoteLogging</servlet-name>
        <url-pattern>/sdlconsole/remote_logging</url-pattern>
</servlet-mapping>

并在编译期间使用-extra parametr

定义dir

这个解决方案有效，但只有当我设置symbolMaps目录的绝对路径时，有点不切实际;）

现在我的问题是：在Tomcat上使用StackTraceDeobfuscator配置RemoteLoggingServiceImpl的正确方法是什么？

以下是我设置符号目录的方法：

@Override
public void init(ServletConfig config) throws ServletException {
    super.init(config);

    // Synchronized so that in a multi-module deployment, there are no conflicts.
    synchronized (RemoteLoggingServiceImpl.class) {
        // Initialize SLF$j bridge logging to redirect jul logs to slf4j. We remove any
        // default loggers to ensure logging doesn't happen to stdout or stderr.
        java.util.logging.Logger rootLogger = LogManager.getLogManager().getLogger("");
        Handler[] handlers = rootLogger.getHandlers();
        for (Handler handler : handlers) {
            rootLogger.removeHandler(handler);
        }
        SLF4JBridgeHandler.install();
    }

    String moduleName = config.getInitParameter("module.name");
    if (StringUtils.isBlank(moduleName)) {
        _logger.error("No module name defined. Please set the module.name servlet init "
                + "parameter to point to the GWT module and enable extra symbolMaps at "
                + "/extra/<module name>/symbolMaps in the servlet context to facilitate "
                + "deobfuscation of stack traces.");
    } else {
        String path = config.getServletContext().getRealPath(
                "/WEB-INF/deploy/" + moduleName + "/symbolMaps/");

        if (path != null) {
            setSymbolMapsDirectory(path);
        }
    } // end else.
}

如何在Tomcat下配置GWT stacktrace deobfuscator？
