Sticky Code : Spring Property Source Usage

Hi everyone in this post I just wanna share a simple sticky code in Spring MVC which used to mapping your @RequestMapping annotation to a properties file. It’s called Property Source, and it would be an advantage to make your URL Request Mapping more managable. Because you put your URL Request Mapping in a single file. Let’s look at the code

1. Add annotation @PropertySource in your web configuration class

@ComponentScan(basePackages = "com.estartup")
public class WebApplicationConfiguration extends WebMvcConfigurerAdapter
		implements ApplicationContextAware {
	private ApplicationContext applicationContext;
	private org.apache.commons.configuration.Configuration _config = ConfigManager.getConfiguration();

	public void setApplicationContext(ApplicationContext applicationContext) {
		this.applicationContext = applicationContext;
    public static PropertyResourceConfigurer propertyResourceConfigurer() {
		return new PropertySourcesPlaceholderConfigurer();

2. Create a properties file in src/config package which named, add put an example (test)


3. In your Controller class you can put ${test} inside the @RequestMapping annotation, ${test} is taken from which you made before

package com.estartup.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

public class TestController {
	@RequestMapping(method = RequestMethod.GET)
	public String defaultHandler(){
		System.out.println("entering test controller : default handler ");
		return "company/company_list";

Good Luck !!
