How can we log request payload/parameters before and after processing in filter of spring boot application.
For example:
/api/users/auth Body: `name:Vijay, place:bangalore...`
I have to log request body in filter before and after processing the request.
Spring Boot provides the CommonsRequestLoggingFilter for this purpose.
You configure it like so:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;
@Configuration
public class RequestLoggingFilterConfigurer {
@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
filter.setIncludeQueryString(true);
filter.setIncludePayload(true);
// truncate payloads
filter.setMaxPayloadLength(1000);
filter.setIncludeHeaders(false);
filter.setAfterMessagePrefix("Request received: ");
return filter;
}
}
And add a logger definition to your logback.xml like so:
<logger name="org.springframework.web.filter.CommonsRequestLoggingFilter" level="DEBUG">
<appender-ref ref="REQUEST_RESPONSE_FILE_APPENDER"/>
</logger>
CommonsRequestLoggingFilter also puts the request payload in the "after request" log line. Kinda confusing matters if I want to log the response body/payload too.
