db.statement does not capture SQL

[mitht]

The project utilizes com.alibaba.druid.proxy.jdbc.PreparedStatementProxyImpl to enhance the functionality of PreparedStatement. When using the OpenTelemetry agent, the db.statement does not capture the correct SQL. How should I solve this issue? {...db.statement=com.alibaba.druid.proxy.jdbc.PreparedStatementProxyImpl@?}

How should I solve this issue?

I doubt that anybody can give you precise instructions for that without debugging this and figuring out what is wrong. The code for the jdbc instrumentation is in https://github.com/open-telemetry/opentelemetry-java-instrumentation/tree/main/instrumentation/jdbc. Use whatever debugging techniques you know to figure out why it doesn't work.
Alternatively provide a minimal sample application that reproduces your issue so someone else could take a look.

com.alibaba druid 1.2.16

datasource:
driver-class-name: org.postgresql.Driver
type: com.alibaba.druid.pool.DruidDataSource
initialSize: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 'x'
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
filters: stat,wall

If the Druid filters: stat, wall are enabled; db.statement=com.alibaba.druid.proxy.jdbc.PreparedStatementProxyImpl@570c696c; unable to capture SQL.

If you wish for someone to take a look at this you'll have to provide a minimal application that reproduces the issue.
