DUZHI 博客系统 项目简介
DUZHI_BLOG基于 Jpress 进行更新而来的。在上面做了一系列升级,修复bug,等等。在基础上增加了如下功能;1、升级 Jfinal 3.0 、Jfinal-weixin 1.82、增加 lucene search 全文搜索引擎3、增加用户中心4、增加 用户中心 等功能5、优化微信渠道内容,避免无法搜索的场景,解决应用型问题6、自带一套与官网一致的主题组件Jfinal这个就不说了,一个MVC框架。Ehcache缓存框架,因为这个里面考虑的是本地的缓存所以,单机模式,所以在缓存的方案基本是懒加载以及缓存加载模式 public User getUser() {
if (user != null)
return user;
if (getUserId() == null)
return null;
user = UserQuery.me().findById(getUserId());
return user;
}上面是个Content 模型中获取用户的模式。再举个缓存的例子; if (ActionCacheManager.isCloseActionCache()) {
next.handle(target, request, response, isHandled);
return;
}
Action action = JFinal.me().getAction(target, urlPara);
if (action == null) {
next.handle(target, request, response, isHandled);
return;
}
ActionCache actionCache = action.getMethod().getAnnotation(ActionCache.class);
if (actionCache == null) {
actionCache = action.getControllerClass().getAnnotation(ActionCache.class);
if (actionCache == null) {
next.handle(target, request, response, isHandled);
return;
}
}
String originalTarget = (String) request.getAttribute("_original_target");
String cacheKey = StringUtils.isNotBlank(originalTarget) ? originalTarget : target;
String queryString = request.getQueryString();
if (queryString != null) {
queryString = "?" + queryString;
cacheKey += queryString;
}
ActionCacheManager.enableCache(request);
ActionCacheManager.setCacheKey(request, cacheKey);
ActionCacheManager.setCacheContentType(request, actionCache.contentType());
String renderContent = ActionCacheManager.getCache(request, cacheKey);
if (renderContent != null) {
response.setContentType(actionCache.contentType());
PrintWriter writer = null;
try {
writer = response.getWriter();
writer.write(renderContent);
isHandled[0] = true;
} catch (Exception e) {
RenderFactory.me().getErrorRender(500).setContext(request, response, action.getViewPath()).render();
} finally {
if (writer != null) {
writer.close();
}
}
} else {
next.handle(target, request, response, isHandled);
}上面是ActionCacheHandler.java的代码。db.properties由于Jpress 使用初始化模式,判断的就是db.properties 有没有,所以如果没有数据库,已经表结构的情况下,建议使用懒汉模式一步一步安装即可。 rm db.properties
