【泛微E9】实现非系统管理员也能执行清空缓存操作

需求描述

想让某个指定用户（loginid=kk）也能访问系统管理员访问的 OA地址/commcache/cacheMonitor.jsp 页面，执行清空缓存操作。

方法1

操作步骤

步骤1：

修改 WEAVER/ecology/WEB-INF/weaver_security_rules.xml，把指定用户的loginid加入全局 <allow-users>

<allow-users>
    <user>sysadmin</user>
    <user>kk</user>
</allow-users>

步骤2：

修改 weaver/ecology/commcache/commoncache.jsp 文件。

将

<%
User user = (User) session.getAttribute("weaver_user@bean");
if(user == null || !"sysadmin".equals(user.getLoginid())){
	out.print("auth fail, please contact sysadmin...");
	return;
}
%>

修改为：

<%
User user = (User) session.getAttribute("weaver_user@bean");
String loginId = user == null ? "" : user.getLoginid();

if (!"sysadmin".equals(loginId) && !"kk".equals(loginId)) {
    out.print("auth fail, please contact sysadmin...");
    return;
}
%>

步骤3：

执行完上述2个步骤后，重启resin服务。

        String action = getParam(params, PARAM_ACTION);

                                + "，表缓存数量===>" + tableCacheCountBefore);

                // 与 commoncache.jsp 中 isreload=1 时执行的操作完全相同。
                cacheFactory.reset();

                int sqlCacheCountAfter = cacheFactory.getCacheMap().getSize();
                int tableCacheCountAfter = cacheFactory.getTableMap().size();

                ret.put("code", "0");
                ret.put(
                        "msg",
                        "公共缓存配置重载完成，SQL缓存："
                                + sqlCacheCountBefore + " -> " + sqlCacheCountAfter
                                + "，表缓存："
                                + tableCacheCountBefore + " -> " + tableCacheCountAfter);

                bbLog.writeLog("公共缓存重载完成===>" + ret.get("msg"));
            } catch (Exception e) {
                ret.put("code", "-1");
                ret.put("msg", "公共缓存配置重载失败：" + e.getMessage());
                bbLog.writeLog("公共缓存重载异常===>" + e);
            }
        }

        return ret;
    }

    private String getParam(Map<String, Object> params, String key) {
        if (params == null) {
            return "";
        }
        Object value = params.get(key);
        return value == null ? "" : String.valueOf(value).trim();
    }
}

接口测试传入 reloadCommonCache 即可实现清空缓存的效果。
