JEECMS v3.0.1 beta版发布,采用的是采用hibernate3+spring mvc+spring2+freemarker主流技术架构.
首先对web.xml分析一下
这里面用的是springmvc的配置

分析jeecms filter配置
几个公用的filter
<filter>
<filter-name>processTime</filter-name>
<filter-class>com.jeecms.common.web.ProcessTimeFilter</filter-class>
</filter>
可以记录处理时间的在外面统计加,感觉比原来在程序内部加的好.包括整个处理流程中的时间都会记录
processTime被配置在过滤器的最前端
下面是编码encoding过滤器
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
默认字符编码是utf-8
下面是编码osivFilter过滤器
<filter>
<filter-name>osivFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
一个Request的处理周期内，Session都是Open
对这几个filter
处理不同的扩展名的请求:*.do,*.jspx,*.jhtml,*.htm,*.jsp
processTime
à
?
encoding
à
?
osivFilter
后台处理过滤器
JeeCmsAdmin
/jeeadmin/jeecms/*
Jeecms路径前台采用的是二级路径,不属于后台的请求被前台的filter拦截
JeeCmsFront
*.do,*.jspx,*.jhtml,*.htm,*.jsp
验证码
Jcaptcha
/captcha.svl
DbFile
/dbfile.svl
在com.jeecms.cms.action.front. DynamicPageAct中预处理这些请求如/news/index.jhtml
/**
* <pre>
* 映射所有路径到 这个方法如 /news/index.jhtml
</pre>
*/
@RequestMapping(value={"/**/*.*"}, method={org.springframework.web.bind.annotation.RequestMethod.GET})
public String dynamic(HttpServletRequest request, HttpServletResponse response, ModelMap model)
{
int pageNo = URLHelper.getPageNo(request);
String[] params = URLHelper.getParams(request);
URLHelper.PageInfo info = URLHelper.getPageInfo(request);
String[] paths = URLHelper.getPaths(request);
int len = paths.length;
if (len == 1)
{
return channel(paths[0], pageNo, params, info, request, response,
model);
}if (len == 2) {
if (paths[1].equals("index"))
{
return channel(paths[0], pageNo, params, info, request,
response, model);
}
try
{
Integer id = Integer.valueOf(Integer.parseInt(paths[1]));
return content(id, pageNo, params, info, request, response,
model);
} catch (NumberFormatException e) {
log.debug("Content id must String: {}", paths[1]);
return FrontUtils.pageNotFound(request, response, model);
}
}
log.debug("Illegal path length: {}, paths: {}", Integer.valueOf(len), paths);
return FrontUtils.pageNotFound(request, response, model);
}
DynamicPageAct中将处理首页请求”/”和”/index.jhtml”
@RequestMapping(value={"/"}, method={org.springframework.web.bind.annotation.RequestMethod.GET})
public String index(HttpServletRequest request, ModelMap model)
{
CmsSite site = CmsUtils.getSite(request);
FrontUtils.frontData(request, model, site);
return FrontUtils.getTplPath(request, site.getSolutionPath(),
"index", "tpl.index");
}
@RequestMapping(value={"/index.jhtml"}, method={org.springframework.web.bind.annotation.RequestMethod.GET})
public String indexForWeblogic(HttpServletRequest request, ModelMap model)
{
return index(request, model);
}
例如运行访问首页运行结果
/WEB-INF/t/cms/www/red
CmsSite.java
public String getSolutionPath()
{
return "/WEB-INF/t/cms/" + getPath() + "/" + getTplSolution();
}
首页处理方法会返回到对应的视图:下面的首页地址
/WEB-INF/t/cms/www/red/index/首页.html
DynamicPageAct.java
@RequestMapping(value={"/"}, method={org.springframework.web.bind.annotation.RequestMethod.GET})
public String index(HttpServletRequest request, ModelMap model)
{
CmsSite site = CmsUtils.getSite(request);
FrontUtils.frontData(request, model, site);
return FrontUtils.getTplPath(request, site.getSolutionPath(),
"index", "tpl.index");
}
