Easy to configure logging filter for servlet containers. Just create an instance of LoggingFilter, configure which messages to log and how to conditionally modify the logged content and you are done. All done with few lines of pure Java.
LoggingFilter filter = new LoggingFilter();
// do not log requests to health probe
filter.registerSkipCondition(requestUriContains("/health");
// if the response is json, then pretty print it
filter.registerTransform(hasResponseContentType("application/json"), prettyPrintJsonResponseBody());
Besides the helpers like requestUriContains that you can find from Conditions and Transforms classes, you can easily write your own transformations and conditions with Java 8 lambda expressions:
// let's only log error messages
filter.registerSkipCondition(exchange -> exchange.response.status == 200);
When you have your LoggingFilter configured the way you want it, just introduce it to your servlet container.
@Bean
Filter myLoggingFilter() {
LoggingFilter filter = new LoggingFilter();
// .. configure here like you want it
return filter;
}
