javaspringxml-configuration
Could not resolve placeholder in XML-config spring app
I am a beginner in spring. I read many similar titled questions on SO and either they weren't working for me or it wasn't that type of configuration and I couldn't understand what was wrong.
I am writing a simple spring application in Intellij Idea with Gradle. Everything was working well untill I decided to read some values from a .properties file. Both xml-config file and .properties files are in resources.
I created a simple junit test. The implementation of LoginService is valid, since when email and password were hardcoded in xml, the test has passed.

Test class (showcase how I read the xml):
import com.doszke.isf.java.spring.service.Login;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import static org.junit.Assert.assertNotNull;
public class MyDocumentsLoginTest {
private static final String EMAIL = "[email protected]";
private static final String PASS = "test123";
private static final String SUCCESS = "Authorized";
private static final String FAILURE = "Authorization failed";
private ClassPathXmlApplicationContext context;
@Before
public void setup(){
context = new ClassPathXmlApplicationContext("META-INF/spring/MyDocuments-config.xml");
}
@Test
public void testLogin(){
Login login = context.getBean(Login.class);
assertNotNull(login);
System.out.println(login.isAuthorized(EMAIL, PASS) ? SUCCESS : FAILURE);
}
}
This is how my project structure looks like:
@Update: env_dev.properties file:
[email protected]
user.password=test123
Solution
In applicationContext.xml, change to this :
