以Curl格式在Elasticsearch中启用Java REST客户端日志记录

我正在使用org.elasticsearch.client.RestHighLevelClient运行查询

根据官方文档，可以用curl格式记录请求：

我在log4j.properties中添加了以下行：

log4j.logger.org.elasticsearch.client = debug

---

现在我看到http请求，但是，如何设置curl格式？

根据他们的文档，您需要启用特定的跟踪记录器，该记录器专门负责curl格式响应

您可以在log4j1.x中通过以下几行实现这一点：

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d{yyyy-MM-dd HH:mm:ss}] [%-5p] %c{1}:%L - %m%n

log4j.logger.tracer=TRACE, stdout

为RestHighLevelClient 7启用跟踪。版本+显示弹性客户端进行的rest调用的url。执行以下步骤

如果基于maven，则在pom中添加依赖项 slf4j api、slf4j-log4j12、jcl-over-slf4j:slf4j使log4j与弹性体使用的公共日志一起工作 logback经典：elastic使用的commons日志记录 log4j核心，log4japi:log4j2依赖关系 在log4j属性中启用跟踪程序 log4j.logger.tracer=跟踪，标准输出 文件级更改 在pom.xml中添加这些依赖项

为了防止有人不想为日志记录者操心，可以在QueryBuilder上调用toString并查看请求

对于log4j版本2.x，在log4j2.properties文件中添加以下配置

status = error
name = PropertiesConfig
filters = threshold
filter.threshold.type = ThresholdFilter
filter.threshold.level = debug
appenders = console
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT
log4j.logger.tracer=TRACE, stdout

# Debugging elasticsearch client
loggers=esclient, esclientsniffer, tracer

logger.esclient.name = org.elasticsearch.client
logger.esclient.level = trace
logger.esclient.appenderRefs = stdout
logger.esclient.appenderRef.stdout.ref = STDOUT

logger.esclientsniffer.name = org.elasticsearch.client.sniffer
logger.esclientsniffer.level = trace
logger.esclientsniffer.appenderRefs = stdout
logger.esclientsniffer.appenderRef.stdout.ref = STDOUT

logger.tracer.name=tracer
logger.tracer.level=trace
logger.tracer.appenderRefs = stdout
logger.tracer.appenderRef.stdout.ref = STDOUT
