import org.apache.commons.jexl3.*;public class MyJEXL {    public static void main(String[] args) {        JexlEngine jexl = new JexlBuilder().create();        String jexlExp = "person.getName()";        JexlExpression jexlExpression = jexl.createExpression(jexlExp);        JexlContext jexlContext = new MapContext();        Person person = new Person("aaa", "20");        jexlContext.set("person", person);        Object o = jexlExpression.evaluate(jexlContext);        System.out.println(o);    }}
