MiinFrameWork是国内开源java企业网站系统MiinCMP内集成的一款轻量级小内存的框架。现在对MiinFrameWork进行简要介绍。
以企业网站产品为例，现在有MiinFrameWork实现CRUD功能。
查询产品对象：
public class ShopProductEntryService {
public ShopProduct getByTitleCatId(String title, int catid) {
// throw new UnsupportedOperationException("Not yet implemented");
String sqlCondation=" title='"+title+"' and catid="+catid;
return getObjectBySQL(sqlCondation);
}
}
添加产品数据：
public void add() throws ServletException, Exception{
this.securityControler.checkPermission();
//load
ShopProduct item= this.formFacede.formToEntry_add(getRequest());
java.util.Date date=new java.util.Date(System.currentTimeMillis());
item.setAddTime(date);
this.setAttribute("ShopProduct",item);
this.setAttribute("info", "添加成功，"+item.getTitle()+"!");
String title=item.getTitle();
int catid=item.getCatid();
ShopProduct itemSaved=entryService.getByTitleCatId(title,catid);
if(itemSaved!=null){
this.setAttribute("info", "产品已存在，标题："+title);
goTo("info");
}else{
entryService.add(item);
itemSaved=entryService.getByTitleCatId(title,catid);
}
//load article content
String contentEditor=this.getParam("contentEditor");
if(contentEditor==null){
this.setAttribute("info", "产品不能为空！");
goTo("info");
}
System.out.println("content Len:"+contentEditor.length());
ProductContentFileUtil fileUtil=new ProductContentFileUtil(this.getRealPath());
fileUtil.saveContent(itemSaved, contentEditor,"utf-8");
// goTo("admin_index");
String prefix="ArticleAdmin";
String controlerUrl_admin="/MyApp/miinshop/admin/"+prefix+"/controller.jsp?act=admin&catid="+catid;
this.forwardUrl(controlerUrl_admin);
}
保存产品数据：
public void update() throws ServletException, Exception{
this.securityControler.checkPermission();
ShopProduct item= this.formFacede.formToEntry_update(getRequest());
System.out.print("########### update article:");
entryService.update(item);
//load article content
String contentEditor=this.getParam("contentEditor");
if(contentEditor==null){
this.setAttribute("info", "文章不能为空！");
goTo("info");
}
System.out.println("content Len:"+contentEditor.length());
ProductContentFileUtil fileUtil=new ProductContentFileUtil(this.getRealPath());
fileUtil.saveContent(item, contentEditor,"utf-8");
this.setAttribute("info", "修改成功，"+item.getTitle()+"!");
int catid=item.getCatid();
String prefix="ArticleAdmin";
String controlerUrl_admin="/MyApp/miinshop/admin/"+prefix+"/controller.jsp?act=admin&catid="+catid;
this.forwardUrl(controlerUrl_admin);
// goTo("admin_index");
}
public void delete() throws ServletException, Exception{
this.securityControler.checkPermission();
int id=Integer.parseInt(this.getParam("id"));
ShopProductEntryService dao=entryService;
ShopProduct item=dao.get(id);
int catid=item.getCatid();
dao.delete(id);
this.setAttribute("info", "删除成功，ID："+id+"!");
String prefix="ArticleAdmin";
String controlerUrl_admin="/MyApp/miinshop/admin/"+prefix+"/controller.jsp?act=admin&catid="+catid;
this.forwardUrl(controlerUrl_admin);
//goTo("admin_index");
}
产品管理的MCV三层结构控制器Contorler类
public class ProductAdminControler extends MiinBaseContraler {
//private String urlPath="/MyApp/miinshop/";
//private String classPath="miinshop.entryControler.ShopProductControler";
private ShopProductFormFacade formFacede=new ShopProductFormFacade();
private SecurityControler securityControler ;
private ShopProductEntryService entryService=new ShopProductEntryService();
public ProductAdminControler(HttpServletRequest request,HttpServletResponse response){
super(request,response);
this.securityControler=new SecurityControler(request,response);
init();
}
public void init(){
String prefix="ArticleAdmin";
//初始化控制器跳转页面
String loginjsp="/MyApp/miinshop/admin/login.jsp";
this.addMapping("loginjsp",loginjsp,false);
String admin_index="/MyApp/miinshop/admin/"+prefix+"/index.jsp?act=admin";
this.addMapping("admin_index",admin_index,false);
String controlerUrl="/MyApp/miinshop/admin/"+prefix+"/controller.jsp";
this.addMapping("controlerUrl",controlerUrl,false);
//crud
String add="/MyApp/miinshop/admin/"+prefix+"/add.jsp";
this.addMapping("add",add,false);
String update="/MyApp/miinshop/admin/"+prefix+"/update.jsp";
this.addMapping("update",update,false);
String list="/MyApp/miinshop/admin/"+prefix+"/list.jsp";
this.addMapping("list",list,false);
String view="/MyApp/miinshop/admin/"+prefix+"/view.jsp";
this.addMapping("view",view,false);
//addInit_cat_selectjsp
String addInit_cat_selectjsp="/MyApp/miinshop/admin/"+prefix+"/addInit_cat_select.jsp";
this.addMapping("addInit_cat_select",addInit_cat_selectjsp,false);
//info
String sysmsgjsp="/MyApp/miinshop/admin/base/info.jsp";
this.addMapping("info",sysmsgjsp,false);
//控制器配置
this.setControllerClassType("miinshop.admin.controler.articleCat.ArticleCatAdminControler");
this.setControllerUrl("/MyApp/miinshop/admin/ArticleCatAdmin/index.jsp");
this.setControllerName("文章分类管理控制器");
}
public void excute() throws Exception {
this.securityControler.checkPermission();
String act=this.getParam("act");
if(act==null){
admin();
}else if(act.equals("add")){
this.add();
}else if(act.equals("updateInit")){
this.updateInit();
}else if(act.equals("view")){
this.view();
}else if(act.equals("list")){
this.list();
}else if(act.equals("admin")){
this.admin();
}else if(act.equals("addInit")){
addInit();
}else if(act.equals("addInit_cat_select")){
addInit_cat_select();
} else if(act.equals("update")){
this.update();
}else if(act.equals("delete")){
this.delete();
}
//addInit_cat_select
}
}
