编码习惯--日志

1、详细的日志打印可以帮助更好的排查问题

@ServiceActivator(inputChannel = "fileChannel")
    public void processFile(Message<File> message) throws IOException {
        securityUtil.logInAs("system");

        File payload = message.getPayload();
        logger.info(">>> Processing file: " + payload.getName());

        String content = FileUtils.readFileToString(payload, "UTF-8");

        SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yy HH:mm:ss");

        logger.info("> Processing content: " + content + " at " + formatter.format(new Date()));

        ProcessInstance processInstance = processRuntime.start(ProcessPayloadBuilder
                .start()
                .withProcessDefinitionKey("categorizeProcess")
                .withProcessInstanceName("Processing Content: " + content)
                .withVariable("content", content)
                .build());
        logger.info(">>> Created Process Instance: " + processInstance);

        logger.info(">>> Deleting processed file: " + payload.getName());
        payload.delete();

    }
