如何仅从主要方法写入日志

Question

我已将 log4j 添加到我的 groovy 脚本中，在其中我使用 httpBuilder 发出一些请求并尝试记录必要的信息，但是当日志级别为 DEBUG 时，我会看到来自我不需要的 HttpBuilder 方法的日志。我怎样才能只写我想要的日志？

我的意思是我

main()
def main() {
    Log4JLogger logger = new Log4JLogger('LOGGERRR')
    logger.info("!!!!!!!!!!!!!!!!!!")
    def httpReq = new HTTPBuilder("${url}")
    httpReq.request(Method.GET, ContentType.JSON) {
    headers.'Authorization' = "Basic ${authString}"         
           response.success = { resp ->
               println("Ok")
           }
           response.failure = { resp ->
               println("Not ok")
           }   
}

这里是 log4j.properties

log4j.rootLogger=DEBUG, file

# Appender 
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
# Path
log4j.appender.file.File=./log_file.log

log4j.appender.file.Append=false
log4j.appender.file.DatePattern='.'yyyy-MM-dd-a

# configuring pattern
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p [%t]:%L - %m%n

这是日志文件的一部分

2020-01-20 17:26:32 DEBUG [main]:73 -  << "HTTP/1.1 200 200[\r][\n]"
.... and so on

但我只需要将第一个字符串写入日志文件。

只需稍微修改log4j.properties 并仅为您命名为LOGGERRR 的记录器指定DEBUG 级别：

# set default logger to ERROR level
log4j.rootLogger=ERROR, file
# set your custom logger to DEBUG level
log4j.logger.LOGGERRR=DEBUG, file

...
