[Freemarker]-call freemarker's FTL template method using struts component

The component tag in struts can be used to call the FTL template file of freemarker. The parameter passing using the component tag can be written as follows:

Using the property method:

    <s:component template="gridComponent.ftl" templateDir="/WEB-INF/template">           <s:param name="grid" value="userss"></s:param>    </s:component>

 

Use the get/set attribute method of the request:

    <s:component template="gridComponent.ftl" templateDir="/WEB-INF/template">           <s:param name="grid" value="#request.users"></s:param>    </s:component>

 

The following describes how to use FTL read parameters:

<#assign s=JspTaglibs["/struts-tags"] /><#assign req = parameters.grid /><#list req as item>    ${item["userName"]}</#list>

 

Common struts action:

Package COM. obs. actions. admin; import Java. util. list; import Org. apache. struts2.servletactioncontext; import Org. springframework. stereotype. controller; import COM. obs. actions. baseadminactionsupport; import COM. obs. actions. bean. user; import COM. obs. util. common; @ controller @ suppresswarnings ("serial")/* @ namespace ("/admin") @ results ({@ result (name = "success ", location = "/WEB-INF/View/admin/user. JSP ")}) */public class useraction extends baseadminactionsupport {private list <user> userss; public list <user> getuserss () {return userss ;} public void setuserss (list <user> userss) {This. userss = userss;}/*** by default, the page executes action */@ override Public String execute () throws exception {// obtain the list of all users <COM. obs. service. bean. user> userlist = super. userservice. findusers (); // copy bean list <user> Users = Common. copyproperties (userlist, user. class); userss = users; // set the action bean to the page servletactioncontext. getrequest (). setattribute ("users", users); Return success ;}}

 

Userss is property, and users is the attribute of request.
