Change order of TextOutputFormat enum and give `CONTENT_TYPE_OPENZIPKIN_JSON_V2`
highest ordinal value, so that it will be matched first by spring-boot-actuator
and in case of default Accept header JSON data will be returned.
Fixes gh-1990
When using `@ValuePropertySource` in reactive web app,
`KafkaSender` bean is getting created before `BeanPostProcessor` populate `@Value`
and as a result topic is passed as `null` in `KafkaSender.Builder` and it throws `NullPointerException`
To resolve this we are using `Environment` to get the property value instead on relying on `BeanPostProcessor`
to populate `@Value`
Handle BeanCreationException instead of just BeanCurrentlyInCreationException.
This handles the case when a cyclic reference (causing a BeanCurrentlyInCreationException) occurs further down the line - when it is not the actuator of that references the in-creation HttpTracing bean, but a dependency of that actuator. In this case the exception that bubbles up here is an UnsatisfiedDependencyException, which is a BeanCreationException
* Fix datasource-proxy log-level is not working
- Aligned default values of `Query` & `SlowQuery` in
`TraceJdbcProperties.DataSourceProxyProperties`
and `DataSourceProxyProperties`
- Add code to copy properties of `Query` and `SlowQuery` in
`DataSourceProxyConfiguration`
- Add test case to check if `log-level` can be override or not.
Fixes gh-1973
* Disable query log listener by default
- By default `QueryLogListener` and `LoggingQueryLogListener`
will be disabled, dev need to enable it by using properties
- By default `Slf4j` will be enlabled for query logging
so by adding below property slow query logging will be enabled
`spring.sleuth.jdbc.datasource-proxy.slow-query.enable-logging=true`
this property will register `SLF4JSlowQueryListener`
* Add docs for how-to enable data-proxy query logs
