java中使用Aviator达式引擎处理表达式判断

Map<String, Object> env = new HashMap<String, Object>();
env.put("email", "test@email.com");
String name = 
(String)AviatorEvaluator.execute("email=~/([\\w0-8]+@\\w+[\\.\\w+]+)/ ? $1:'unknow'", env);

import com.googlecode.aviator.AviatorEvaluator;
for (LERule lERule:lERules) {
            String rulePatternTemplate = lERule.getRulePattern();
            String rulePatternStr = 
FreemarkerTemplateUtil.processFreemarker(rulePatternTemplate, bPBody.getBPInfo());
            if(StringUtils.isNotBlank(rulePatternStr)){
                boolean isEvent = (Boolean) AviatorEvaluator.execute(rulePatternStr);
                if(isEvent){
                    lEList.add(lERule.getLE());
                }
            }
        }
