This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened.

Usage

From source file:org.codehaus.groovy.grails.scaffolding.AbstractGrailsTemplateGenerator.java

protected String getTemplateText(String template) throws IOException {
    InputStream inputStream = null;
    if (resourceLoader != null && grailsApplication.isWarDeployed()) {
        inputStream = resourceLoader.getResource("/WEB-INF/templates/scaffolding/" + template).getInputStream();
    } else {//from w  w w .  jav  a2 s . c om
        AbstractResource templateFile = getTemplateResource(template);
        if (templateFile.exists()) {
            inputStream = templateFile.getInputStream();
        }
    }

    return inputStream == null ? null : IOGroovyMethods.getText(inputStream);
}
