Struts使用Freemarker做模板显示List

Struts使用Freemarker做模板，Action中String类型对象可以直接使用

List需要借助request传递

struts.xml

<package name="/test" extends="struts-default" namespace="/test">

<action name="query" class="testAction" method="queryTest">
<result name="success" type="freemarker">/jsp/test.ftl</result>
</action>
</package>

TestAction

private List<User> users;

public String queryUser(){
//get users from database
List<User> users=...;

Map request = (Map)ActionContext.getContext().get("request");
request.put("users", users);

return SUCCESS;
}

test.ftl:

<#list users as user>
<tr>
<td>${user.userName}</td>
<td>${user.userId}</td>
</tr>
</#list>
