Example 21 with SpelExpressionParser

use of org.springframework.expression.spel.standard.SpelExpressionParser in project spring-framework by spring-projects.

the class ScenariosForSpringSecurity method testScenario04_ControllingWhichMethodsRun.

// Here i'm going to change which hasRole() executes and make it one of my own Java methods
@Test
public void testScenario04_ControllingWhichMethodsRun() throws Exception {
    SpelExpressionParser parser = new SpelExpressionParser();
    StandardEvaluationContext ctx = new StandardEvaluationContext();
    // so non-qualified references 'hasRole()' 'hasIpAddress()' are invoked against it);
    ctx.setRootObject(new Supervisor("Ben"));
    // NEEDS TO OVERRIDE THE REFLECTION ONE - SHOW REORDERING MECHANISM
    ctx.addMethodResolver(new MyMethodResolver());
    // Might be better with a as a variable although it would work as a property too...
    // Variable references using a '#'
    //		SpelExpression expr = parser.parseExpression("(hasRole('SUPERVISOR') or (#a <  1.042)) and hasIpAddress('10.10.0.0/16')");
