Spring Start Analyser

This project is designed as a module which you can bring in via maven and it will produce a graph similar to below which shows the construction times of each spring bean.

How to use

Import the module as a maven dependency.

<dependency>
    <groupId>com.github.lwaddicor</groupId>
    <artifactId>spring-startup-analysis</artifactId>
    <version>1.0.0</version>
</dependency>

Either add to your component scanning the following base package

com.github.lwaddicor.springstartupanalysis

or

<bean class="com.github.lwaddicor.springstartupanalysis.web.SpringStartupController"/>
<bean class="com.github.lwaddicor.springstartupanalysis.StartProgressBeanPostProcessor"/>

Now you should be able to start up your servlet and navigate to the endpoint. For example

http://localhost:8080/spring-startup/

And view something very similar to the example.
