Spring 数据 R2DBC 中查询参数的日志值？

Question

在 Spring Data R2DBC 中，我可以使用

记录 SQL 个查询

logging.level.org.springframework.data.r2dbc=DEBUG

在 application.properties.

但是，这不会记录绑定为查询参数的实际值。

如何在 Spring Data R2DBC 中记录查询参数的实际值？

Answer 1

如果您碰巧使用 MySQL，您可以通过将驱动程序的日志级别设置为 TRACE.

来获取与数据库服务器的所有通信的低级别网络转储

logging.level.ROOT=TRACE
logging.level.dev.miku.r2dbc.mysql.client.ReactorNettyClient=TRACE

示例输出：

19-11-2020 00:03:28.072 TRACE [reactor-tcp-nio-2] d.m.r.mysql.client.ReactorNettyClient - [id: 0x9cf29125, L:/127.0.0.1:63807 - R:localhost/127.0.0.1:33306] READ: 71B

Answer 2

这对我有用：

 logging:
  level:
    io.r2dbc.postgresql.QUERY: DEBUG # for queries
    io.r2dbc.postgresql.PARAM: DEBUG # for parameters

找到了here

Answer 3

对于 h2 和其他数据库尝试：

logging.level.io.r2dbc.h2=TRACE

我必须更新源代码以在 mysql r2dbc 中记录参数化 sql 语句。这是我的方法：

然后更改logback中TextQueryMessage的日志级别-spring.xml:

<logger name="dev.miku.r2dbc.mysql.message.client.TextQueryMessage" level="DEBUG" additivity="false">
    <appender-ref ref="async_file"/>
