当Mvel表达式键中包含空格时，我将得到错误提示
Map<String, Object> input = new HashMap<String, Object>();
input.put("na me", "prachi");
input.put("prid", 10);
final String expression = "(na me == \"prachi\") && (prid > 5 && prid < 20)";
System.out.println("Mvel output "+MVEL.evalToBoolean(expression, input ));
Error: Exception in thread "main" [Error: unresolvable property or identifier: na]
[Near : {... (na me == "prachi") && (price>1 ....}]
