I have a maven Spring project, there is xml file inside src/main/resources/xyz.xml. How can I read it inside spring MVC controller.

I am using 

InputStream is = getClass().getResourceAsStream("classpath:xyz.xml");

but is is null.

Reset to default

Resource resource = new ClassPathResource(fileLocationInClasspath); InputStream resourceInputStream = resource.getInputStream();

using ClassPathResource and interface resource. But make sure you are copying the resources directory correctly (using maven), and its not missing, for example if running tests as part of test context.

In this case, fileLocationInClasspath should not start with "classpath:".
does this work if I need to read a folder from src/main/resources

For spring based application you can take advantage of ResourceUtils class.

File file = ResourceUtils.getFile("classpath:xyz.xml")

Here is one way of loading classpath resources.

Resource resource = applicationContext.getResource("classpath:xyz.xml"); InputStream is = resource.getInputStream();

Hey Robby, this is super helpful but Kenji and I are wondering how you would then parse a file line by line from the input stream.

You can add a field with annotation @Value to your bean:

@Value("classpath:xyz.xml") private Resource resource;

And then simply:

resource.getInputStream();

Best working code in Dec 14, 2019 (Spring version 5.1.0.RELEASE)

import org.springframework.core.io.Resource; import org.springframework.core.io.ClassPathResource; import java.io.File; import java.io.InputStream; Resource resource = new ClassPathResource("xyz.xml"); InputStream input = resource.getInputStream(); File file = resource.getFile();

Using ClassPathResource is exactly what I was looking for since it eliminates the need to write classpath: in the file path. Thanks for sharing this.
