iText7 - 如何设置LoggerFactory？ [英] iText7 - How to set up LoggerFactory?

问题描述

我今天刚刚开始使用iText，所以我开始运行教程＃1中的示例。不幸的是我收到这些错误消息：

I just started using iText today so I started by running the example in Tutorial #1. Unfortunately I get these error messages:

Exception thrown: 'System.NullReferenceException' in itext.io.dll
iText.IO.Log.LoggerFactory: No logger factory was bound. Defaulting to no-operation logger implementation.
iText.IO.Log.LoggerFactory: In order to bind a logger factory use     iText.IO.Log.LoggerFactory.BindFactory().

显然我还没有设置一个名为LoggerFactory的东西。我该怎么做？

Obviously I haven't set up something called LoggerFactory. How do I do that?

推荐答案

我们遇到了与C＃iText7项目类似的情况，其中

We ran into a similar situation with a C# iText7 project, where

iText.IO.Log.LoggerFactory: No logger factory was bound. Defaulting to no-operation logger implementation.
iText.IO.Log.LoggerFactory: In order to bind a logger factory use     iText.IO.Log.LoggerFactory.BindFactory().

...每次我们尝试运行流程时都会记录，只要我们尝试访问任何iText类。

...would be logged every time we tried to run the process, as soon as we tried to access any iText classes.

我们通过在程序开头添加以下代码来解决这个问题：

We got around this by adding the following code to the beginning of our program:

iText.IO.Log.NoOpLoggerFactory iTextLoggerFactory = new iText.IO.Log.NoOpLoggerFactory();
iText.IO.Log.LoggerFactory.BindFactory(iTextLoggerFactory);
