How to log properly http requests with Spring MVC

EDIT: Also, see @membersound’s comment on this answer, which improves this answer.

Spring supports this. See CommonsRequestLoggingFilter. If using Spring Boot, just register a bean of that type and Boot will apply it to the filter chain. Like:

@Bean
public Filter logFilter() {
    CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
    filter.setIncludeQueryString(true);
    filter.setIncludePayload(true);
    filter.setMaxPayloadLength(5120);
    return filter;
}

Also, this logging filter requires the log level be set to DEBUG. E.g. do this in a logback.xml with:

<logger name="org.springframework.web.filter.CommonsRequestLoggingFilter" level="DEBUG"/>
