This paper mainly studies the springboot2 custom HttpTraceRepository
Configuration
@Configuration
@ConditionalOnWebApplication
@ConditionalOnProperty(prefix = "management.trace.http", name = "enabled", matchIfMissing = true)
@EnableConfigurationProperties(HttpTraceProperties.class)
@AutoConfigureBefore(HttpTraceAutoConfiguration.class)
public class TraceConfig {
@Bean
@ConditionalOnMissingBean(HttpTraceRepository.class)
public RemoteHttpTraceRepository traceRepository() {
return new RemoteHttpTraceRepository();
}
}A new configuration has been added here, and traceRepository has been customized before HttpTraceAutoConfiguration.
RemoteHttpTraceRepository
public class RemoteHttpTraceRepository implements HttpTraceRepository {
private static final Logger LOGGER = LoggerFactory.getLogger(RemoteHttpTraceRepository.class);
@Override
public List<HttpTrace> findAll() {
return Collections.emptyList();
}
@Override
public void add(HttpTrace trace) {
//send log to remote server or log center
LOGGER.info(JSON.toJSONString(trace));
}
}Custom RemoteHttptraceRepository, you can output Trace to the log server by yourself in the add method
Summary
By customizing the HttpTraceRepository, it is very convenient for the webflux project to implement its own accesslog similar to tomcat.
