我已经在log4j2中成功地使用了它

appender.csvSummary.type = File
appender.csvSummary.name = CSVSUMMARY
appender.csvSummary.append=false
appender.csvSummary.fileName = ${csvPrefix}-${SUM}-${date:yyyy-MM-dd-HH-mm-ss}.csv
appender.csvSummary.layoutString.type = CsvParameterLayout
appender.csvSummary.layoutString.delimiter = ,
appender.csvSummary.layoutString.header = path,test_name,outcome\n

要使用csvparameterlayout，请确保设置了以下依赖项。

<dependencies>
 <dependency>
  <groupId>org.apache.logging.log4j</groupId>
  <artifactId>log4j-api</artifactId>
  <version>2.4</version>
 </dependency>
 <dependency>
  <groupId>org.apache.logging.log4j</groupId>

 <dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-csv</artifactId>
  <version>1.2</version>

</dependencies>

以前我用log4j.xml来记录2列的行。

<?xml version="1.0" encoding="UTF-8"?>

                     fileName="${csvLog.fileName}.tmp"

            <CsvParameterLayout delimiter="," header="${file-header}\n"/>
