Environment properties not getting read in spring boot

Question

I have a utility class to read the environment variables.

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.stereotype.Component;

@Component
public final class PropertyUtil {

    /** The system environment. */
    private static Environment environment;

    public static String getConfigProp(final String key) {
        return environment.getProperty(key);
    }

    @Autowired
    public void setEnvironment(Environment environment) {
        PropertyUtil.environment = environment;
    }
}

And I use it in one bean while initialization. The problem is that it runs file if I deploy the war file on tomcat but if I run the same application as a spring boot application from eclipse, it does not read the environment properties and the return values are therefore null.

Any idea what could be the cause of this problem?

In my case, environment is getting initialized but just that there are no properties inside. — Popeye, Mar 30 '17 at 09:27

package com.myspringboot.controller;

import org.springframework.context.EnvironmentAware;
import org.springframework.core.env.Environment;
import org.springframework.stereotype.Component;
@Component
public  class PropertyUtil  implements EnvironmentAware {

    /** The system environment. */
    public  Environment environment;

    public  String getConfigProp(String key) {
        return environment.getProperty(key);
    }
    @Override
    public void setEnvironment(Environment arg0) {
        environment=arg0;

    }
}
    @Test
    public void testProperty(){
/*      String driver= System.getenv().get("spring.datasource.driverClassName");
        System.out.println(driver);
        System.out.println(PropertyUtil.environment);*/
        String str= propertyUtil.getConfigProp("spring.datasource.driverClassName");
        System.out.println(str);
    }
