Examples with ExpressionParser org.springframework.expression.ExpressionParser used on opensource projects

Example 56 with ExpressionParser

use of org.springframework.expression.ExpressionParser in project spring-framework by spring-projects.

the class EvaluationTests method testCreateMapsOnAttemptToIndexNull01.

@Test(expected = SpelEvaluationException.class)
public void testCreateMapsOnAttemptToIndexNull01() throws Exception {
    TestClass testClass = new TestClass();
    StandardEvaluationContext ctx = new StandardEvaluationContext(testClass);
    ExpressionParser parser = new SpelExpressionParser(new SpelParserConfiguration(true, true));
    Object o = null;
    o = parser.parseExpression("map['a']").getValue(ctx);
    assertNull(o);
    o = parser.parseExpression("map").getValue(ctx);
    assertNotNull(o);
    o = parser.parseExpression("map2['a']").getValue(ctx);
// map2 should be null, there is no setter
}
