Examples with BeanFactoryResolver org.springframework.context.expression.BeanFactoryResolver used on opensource projects

Example 1 with BeanFactoryResolver

use of org.springframework.context.expression.BeanFactoryResolver in project camel by apache.

the class JpaRouteSharedEntityManagerTest method getBrokerCount.

private int getBrokerCount() {
    LocalEntityManagerFactoryBean entityManagerFactory = applicationContext.getBean("&entityManagerFactory", LocalEntityManagerFactoryBean.class);
    //uses Spring EL so we don't need to reference the classes
    StandardEvaluationContext context = new StandardEvaluationContext(entityManagerFactory);
    context.setBeanResolver(new BeanFactoryResolver(applicationContext));
    SpelExpressionParser parser = new SpelExpressionParser();
    Expression expression = parser.parseExpression("nativeEntityManagerFactory.brokerFactory.openBrokers");
    List<?> brokers = expression.getValue(context, List.class);
    return brokers.size();
}

Example 2 with BeanFactoryResolver

use of org.springframework.context.expression.BeanFactoryResolver in project camel by apache.

the class SpelExpression method createEvaluationContext.

private EvaluationContext createEvaluationContext(Exchange exchange) {
    StandardEvaluationContext evaluationContext = new StandardEvaluationContext(new RootObject(exchange));
    if (exchange.getContext() instanceof SpringCamelContext) {
        // Support references (like @foo) in expressions to beans defined in the Registry/ApplicationContext
        ApplicationContext applicationContext = ((SpringCamelContext) exchange.getContext()).getApplicationContext();
        evaluationContext.setBeanResolver(new BeanFactoryResolver(applicationContext));
    }
