logfile 端点提供对应用程序日志文件内容的访问。
检索日志文件
要检索日志文件，请发送 GET 请求到 /actuator/logfile，如下基于 curl 的示例所示：
curl 'http://localhost:8080/actuator/logfile' -i -X GET得到的响应类似于以下内容：
HTTP/1.1 200 OK

检索日志文件的一部分
| 使用 Jersey 时不支持检索日志文件的一部分。 |
要检索日志文件的一部分，请使用 Range 头发送 GET 请求到 /actuator/logfile，如下基于 curl 的示例所示：
curl 'http://localhost:8080/actuator/logfile' -i -X GET \
-H 'Range: bytes=0-1023'上述示例检索了日志文件的前 1024 字节。得到的响应类似于以下内容：
