Question

By “local filename” I mean that resource file is located in the same directory as class file. In the case below this is JUnitRunner.class file. Java’s getResource() file can handle this if path does not start with /‘

I can’t figure out, how to do the same ClassPathXmlApplicationContext constructor?

package springtests;

import java.io.File;
import java.net.URISyntaxException;
import java.net.URL;

import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class JUnitRunner {

    private final static Logger log = LoggerFactory.getLogger(JUnitRunner.class);

    @Test
    public void test() throws URISyntaxException {

        String filename = "test01.xml";

        URL url = getClass().getResource(filename);


        File file = new File(url.toURI());
        log.info("File exists: {}", file.exists());

        try {
            new ClassPathXmlApplicationContext(filename);
        }
        catch(Exception e) {
            log.error("Can't load context", e);
        }

    }
}

the output follows

15:32:27,375 3    [main] INFO  springtests.JUnitRunner  - File exists: true
15:32:27,422 50   [main] INFO  org.springframework.context.support.ClassPathXmlApplicationContext  - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@ee3aa7: startup date [Thu Nov 01 15:32:27 MSK 2012]; root of context hierarchy

...

UPDATE

XML file is located in the same folder as class file. It is visible from the fact that getResource() see it.

Answer 1

so, your xml file in package springtests and correct creation of AppContext should be

new ClassPathXmlApplicationContext("springtests/test01.xml");
