Java 奥林戈v4+；log4j2

我找不到任何关于Olingo v4系统日志的信息，就像spring boot一样。 本教程包括slf4j，所以在框架中必须有内部日志记录

   <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-simple</artifactId>
      <version>${slf4j.version}</version>
      <scope>runtime</scope>
    </dependency>

在ODataServlet中没有捕获

        try {
            /*session, storage, handler, edm providers init here*/

            // let the handler do the work
            handler.process(req, resp);
        } catch (Exception e) {
            log.error("Server Error occurred in ODataServlet", e); //app is not getting here
            throw new ServletException(e);
        } finally {
            log.debug("========== Request end ==========");
        }

还有我的日志

[DEBUG] ODataServlet - ========== Request begin ==========
[DEBUG] ODataServlet - Received GET request /myOdataServer.svc/$metadata from 0:0:0:0:0:0:0:1
[DEBUG] JDBCFactory - Opening connection to jdbc:postgresql://host/card_storage
[DEBUG] ODataServlet - ========== Request end ==========

我希望从框架中获得更多关于错误的信息：堆栈跟踪、行号等等

        try {
            /*session, storage, handler, edm providers init here*/

            // let the handler do the work
            handler.process(req, resp);
        } catch (Exception e) {
            log.error("Server Error occurred in ODataServlet", e); //app is not getting here
            throw new ServletException(e);
        } finally {
            log.debug("========== Request end ==========");
        }
