JEECMS v3.0.1 beta版源码分析

王刚(个人博客http://1985wanggang.blog.163.com)

 

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

 

<?xml version="1.0" encoding="UTF-8"?>

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

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/””/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");

   }
