关键字过滤

manager中的过滤方法，其中用到了alibaba的StringUtil类
在toolkit-common-lang-1.0.jar里面的
com.alibaba.common.lang.StringUtil

public String filterString(String body) {
   if (body == null) {
    return body;
   }
   String back = body;
   List customerTaboos = customerTabooDAO.loadTaboosFromMap();

   for (int i = 0; i < customerTaboos.size(); i++) {
    CustomerTaboo taboo = (CustomerTaboo) customerTaboos.get(i);
    String origal = taboo.getTaboo();
    String replace = taboo.getReplacement();
    back = StringUtil.replace(back, origal, replace);
   }
   return back;
}

DAO层用了个简单的CACHE。不然每次过滤都去数据库拿。。。。就不好了

   return list;
}

public void delete(BigDecimal id) {
