CommonsRequestLoggingFilter not working in spring boot application - spring-boot

Question

I have added this #Bean to the class I have main function in
#Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
System.out.println("inside logging filter");
CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
loggingFilter.setIncludeClientInfo(true);
loggingFilter.setIncludeQueryString(true);
loggingFilter.setIncludePayload(true);
loggingFilter.setIncludeHeaders(false);
return loggingFilter;
}
On application start,
inside logging filter
gets printed in console but I do not see any logging of requests when I call method from a RestController.
Why is that? How do I fix it?
I have already added
logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG
in application.properties file

Answer 1

I have been the same situation and I could resolve it with removing log setting.
logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG
It runs without this setting.
Also, if you want to change log level, you can define the class extends AbstractRequestLoggingFilter and write logging like this.
#Override
protected void beforeRequest(HttpServletRequest request, String message) {
logger.info(message);
}
#Override
protected void afterRequest(HttpServletRequest request, String message) {
logger.info(message);
}

In principle you just need to enable debug on the logger of choice. In effect it is hard to know what logger exatly is used by Spring. The safe way to do it is to override AbstractRequestLoggingFilter and set the logger to a logger of choice. Alternatively is is possible you just override the 'shouldLog' method to return 'true'.
Example in Kotlin
package org.ultra-marine.logging
import org.slf4j.LoggerFactory
import org.springframework.web.filter.AbstractRequestLoggingFilter
import javax.servlet.http.HttpServletRequest
class RequestLoggingFilter: AbstractRequestLoggingFilter() {
private val log = LoggerFactory.getLogger(this::class.java)
override fun shouldLog(request: HttpServletRequest): Boolean {
return log.isDebugEnabled
}
/**
* Writes a log message before the request is processed.
*/
override fun beforeRequest(request: HttpServletRequest, message: String) {
log.debug(message)
}
/**
* Writes a log message after the request is processed.
*/
override fun afterRequest(request: HttpServletRequest, message: String) {
log.debug(message)
}
}
The Filter need to be initialized using a Bean in the same way demonstrated in other places.
#Configuration
class SpringBootRequestLoggingConfiguration {
#Bean
fun requestLoggingFilter(): RequestLoggingFilter {
val filter = RequestLoggingFilter()
filter.setIncludeClientInfo(false)
filter.setIncludeQueryString(true)
filter.setIncludePayload(false)
filter.setMaxPayloadLength(8000)
filter.setIncludeHeaders(false)
return filter
}
}

Answer 3

Try changing the level to TRACE in your application.properties file:
logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=TRACE
DEBUG didn't work for me, but TRACE did.

Answer 4

Fyi if you see an extra ] at the end of the json body you can remove it like this:
loggingFilter.setAfterMessageSuffix("");

Answer 5

you should set the MaxPayloadLength,if you use CommonsRequestLoggingFilter
filter.setMaxPayloadLength(2048);
Or you can implements Filter,then you can customize yourself Filter.
Define a MultiReadHttpServletRequest extends HttpServletRequestWrapper
slove the getInputStream problem.
