How do I log postgres driver messages with slf4j?
New Postgres driver 42.0.0 use java.util.logging, see changelog
To get logs:
Add jul-to-slf4j bridge:
<dependency> <groupId>org.slf4j</groupId> <artifactId>jul-to-slf4j</artifactId> <version>${slf4j.version}</version> </dependency>
Add in logback.xml (logback-test.xml)
<logger name="org.postgresql" level="trace"/>`
Add in code
static { SLF4JBridgeHandler.install(); }
You can set a PrintWriter
as the PostgresQL driver logging destination. For example, if you were using one of the driver data sources, you would use this method.
Now, all you need is an extension of PrintWriter
that sends everything it receives to your logging system. Here is an example from Apache Jackrabbit.
