 public static List<ParamFlowRule> getRulesOfResource(String resourceName) {
        return new ArrayList((Collection)PARAM_FLOW_RULES.get(resourceName));
    }

当PARAM_FLOW_RULES.get(resourceName)为null的时候， new ArrayList就会报空指针异常。
这个在对应的resourceName没有配置规则的时候，就会触发。

it seems that it will not cause npe here, because of the return of PARAM_FLOW_RULES.get(resourceName) will be empty list if not rule configured.
