The perf4j @Profiled annotation does not work


I have gone thru the below link from perf4J site and have done same to same:

Added the following in my spring.xml.

<bean id="timingAspect" class="org.perf4j.log4j.aop.TimingAspect"/>
<bean id="wscClientBase" class=""/>

In class WscClientBase I have the following method with @Profiled annotation.

@Profiled(tag = "SOAPCALLTEST")
public Object sendMessage(Object message) {
    String msg = message.toString();
    if (msg.indexOf(' ') > 1) {
        msg = msg.substring(1, msg.indexOf(' '));
    try {
        Object ret = marshalSendAndReceive(message);
        return ret;
    } catch (RuntimeException ex) {
        throw ex;

I dont see the perf4j TimingLogger statements in the application log. However if I use it obtrusively (without annotation) as below, I see the log statements successfully.

public Object sendMessage(Object message) {
    String msg = message.toString();
    if (msg.indexOf(' ') > 1) {
        msg = msg.substring(1, msg.indexOf(' '));
    StopWatch stopWatch = new Slf4JStopWatch();
    try {
        Object ret = marshalSendAndReceive(message);
        stopWatch.stop("PERF_SUCCESS_TAG", msg);
        return ret;
    } catch (RuntimeException ex) {
        stopWatch.stop("PERF_FAILURE_TAG", msg);
        throw ex;

Am I missing something?

Perf4j This is a performance analysis and checking plugin for application. It can be integrated with spring using spring AOP. It creates a log file that is give to a parser to analyse and produce relevant information. It can provide average,mean, std deviation by default. For more general information please check

How to setup Perf4j. For normal setup you just need to add perf4j jar and create StopWatch instance for every code sniplet you want to monitor.

StopWatch stopWatch= new StopWatch(“snipletTagName”)
//{your code sniplet}

This will create perf4j monitor and you will get logg information on the console.

Main purpose of this documentation is to have a setup by setup understanding of integrating perf4j with spring.

1.Add all Jar file.

 1. perf4j-0.9.16-slf4jonly.jar

Make sure you have all this jar in your class path along with spring library. 2.create your own logback.xml that will be used by perf4j implicitly the content of the logback.xml will be


    <appender name="CoalescingStatistics"
        <param name="TimeSlice" value="1" />
        <appender-ref ref="perf4jFileAppender" />

    <appender name="RootConsoleAppender" class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%date %-5level [%thread] %logger{36} [%file:%line] %msg%n

    <appender name="perf4jFileAppender"
            <Pattern>%date %-5level [%thread] %logger{36} [%file:%line] %msg%n
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

    <!-- Loggers -->
    <!-- The Perf4J logger. Note that org.perf4j.TimingLogger is the value of
        the org.perf4j.StopWatch.DEFAULT_LOGGER_NAME constant. Also, note that additivity
        is set to false, which is usually what is desired - this means that timing
        statements will only be sent to this logger and NOT to upstream loggers. -->
    <logger name="org.perf4j.TimingLogger" additivity="false">
        <level value="DEBUG" />
        <appender-ref ref="CoalescingStatistics" />
        <appender-ref ref="perf4jFileAppender" />
        <appender-ref ref="RootConsoleAppender" />

3.In your spring configuration file you need to add aspectj tag that will enable @Profiled annotation of perf4j.

**> (Note: What is @Profiled annotation?: you will add this tag to all the

methods in all the classes that are called from spring instance or use dependency injection. The object basically should be spring context registered and the method should be invoked by the object that are registered in spring context. I wasted one day thinking why my method was not logged then I realized that the object I tested was not part of spring context.**

OK the code that you need to add to spring configuration xml is.

<!-- this is my spring-context.xml -->
        <aop:include name="timingAspect" />

    <bean id="timingAspect" class="org.perf4j.slf4j.aop.TimingAspect" />

<!-- this is the class that will be registered with the spring and now we can get this class and call the method that we need to monitor-->
    <bean class="com.perf4jexample.Test" />

4.Create the Test class that will implement @Profiled annotation.

public class Test {

    private String testVal;

    public Test() {
        // TODO Auto-generated constructor stub

    public void testing() {
        System.out.println("testt" );

    public String getTestVal() {
        return testVal;

    public void setTestVal(String testVal) {
        this.testVal = testVal;

5.Ok now you have setup every thing just thing remains is test class that will start spring context and with it load perf4j.

public class Test(){

public static void main(){
        AbstractApplicationContext context = new ClassPathXmlApplicationContext(


        Test bean = context.getBean(Test.class);

I hope by following this setups you should be able to perf4j console appender to display one line on console.

Perf4j Monitoring command on the log For Generating Performance statistical information execute on you logger path java -jar perf4j-0.9.16.jar myLogger.log

For Generating Graphs java -jar perf4j-0.9.16.jar --graph perfGraphs.out myLogger.log

I hope this tutorial help you to integrated Spring,perf4j,logback with Profiled annotation.
