查看：88
本文介绍了Log4net缓冲区大小不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我试图将每100条记录输入数据库.如果我将缓冲区大小指定为100，它仍然将每条记录输入数据库.是否有一种方法可以指定刷新间隔和缓冲区大小.首先需要这样做. 这是我的配置.

解决方案

Buffersize仅指定在提交之前应在RAM中保留多少个项目.它没有定义记录器的混乱的程度.

要定义有损记录器，您需要明确声明并定义可能丢失的内容:

<lossy value="true"/>
<evaluator type="log4net.Core.LevelEvaluator">
  <threshold value="ERROR" />
</evaluator>

im trying to enter every 100 records into the database.If i specify the buffer size as 100.It stills enters each record into the database.Is there a way where i can specify the flush interval and buffer size.So which comes first it takes that. This is my config.

解决方案

Buffersize only specifies how many items shall be kept in RAM before committing them. It does not define the Lossyness of the logger.

To define a lossy logger, you need to state that explicitly and define what can be lost:

<lossy value="true"/>
<evaluator type="log4net.Core.LevelEvaluator">
  <threshold value="ERROR" />
</evaluator>
