[guosansan]

示例代码

@Test
    void testVar3() {
        String expression = "age<18";
        Expression compiledExp = AviatorEvaluator.compile(expression);
        List<String> variableNames = compiledExp.getVariableNames();
        logger.info("expression:{} variables:{}", expression, variableNames);

        Map<String, Object> env = new HashMap<>();
        env.put("age", null);

        boolean result = (Boolean) compiledExp.execute(env);
        logger.info("expression execute result:{}", result);
    }

结果日志

expression:age<18 variables:[age]
 expression execute result:true

期望值

返回false
