Example 1 with GroovyShell

use of groovy.lang.GroovyShell in project camel by apache.

the class GroovyExpression method instantiateScript.

@SuppressWarnings("unchecked")
private Script instantiateScript(Exchange exchange) {
    // Get the script from the cache, or create a new instance
    GroovyLanguage language = (GroovyLanguage) exchange.getContext().resolveLanguage("groovy");
    Class<Script> scriptClass = language.getScriptFromCache(text);
    if (scriptClass == null) {
        GroovyShell shell;
        Set<GroovyShellFactory> shellFactories = exchange.getContext().getRegistry().findByType(GroovyShellFactory.class);
        if (shellFactories.size() > 1) {
            throw new IllegalStateException("Too many GroovyShellFactory instances found: " + shellFactories.size());
        } else if (shellFactories.size() == 1) {
            shell = shellFactories.iterator().next().createGroovyShell(exchange);
        } else {
            ClassLoader cl = exchange.getContext().getApplicationContextClassLoader();
            shell = cl != null ? new GroovyShell(cl) : new GroovyShell();
        }
        scriptClass = shell.getClassLoader().parseClass(text);
        language.addScriptToCache(text, scriptClass);
    }
    // New instance of the script
    try {
        return scriptClass.newInstance();
    } catch (InstantiationException e) {
        throw new RuntimeCamelException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeCamelException(e);
    }

@Test

    // Given
    GroovyShellFactory groovyShellFactory = mock(GroovyShellFactory.class);
    given(groovyShellFactory.createGroovyShell(any(Exchange.class))).willReturn(new GroovyShell());
    SimpleRegistry registry = new SimpleRegistry();
    registry.put("groovyShellFactory", groovyShellFactory);
    CamelContext camelContext = new DefaultCamelContext(registry);
    // When
    assertExpression(GroovyLanguage.groovy("exchange.in.body"), new DefaultExchange(camelContext), null);
    // Then
    verify(groovyShellFactory).createGroovyShell(any(Exchange.class));
}
