Struts2与FreeMarker整合
struts.xml 配置
- <?xml?version="1.0"?encoding="UTF-8"??> ??<!DOCTYPE?struts?PUBLIC ??????"-//Apache?Software?Foundation//DTD?Struts?Configuration?2.0//EN"?? ????"http://struts.apache.org/dtds/struts-2.0.dtd"> ?? ??<struts> ????????<constant?name="struts.enable.DynamicMethodInvocation"?value="false"?/> ?? ????<constant?name="struts.devMode"?value="false"?/> ?? ????<package?name="default"?extends="struts-default"> ?? ????????<action?name="test"?class="com.test.TestAction"> ?? ????????????<result?name="success"?type="freemarker">test-success.ftl</result> ?? ????????</action> ??????????<action?name="login"> ?? ????????????<result?type="freemarker">/login.ftl</result> ?? ????????</action> ??????</package> ?? </struts>?
*.ftl 编写
- <#assign?s=JspTaglibs["/WEB-INF/struts-tags.tld"]?/> ??<html> ??<head> ??????<title>Hello</title> ??</head> ??<body> ??<@s.form?action="/test.action"> ?? <@s.textfield?name="name"/> ?? <@s.submit/> ?? </@s.form> ?? </body> ??</html>??
<#assign?s=JspTaglibs["/WEB-INF/struts-tags.tld"]?/>
这一句是为了让Freemarker识别struts2的标签，因为在Freemarker文件内，除了它自己的，都会原样显示。
web.xml 配置
- <?xml?version="1.0"?encoding="UTF-8"?> ??<web-app?id="WebApp_9"?version="2.4"?xmlns="http://java.sun.com/xml/ns/j2ee"??????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"??????xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee?http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> ?? ??????<display-name>Struts?Blank</display-name> ????????<filter> ??????????<filter-name>struts2</filter-name> ??????????<filter-class> ?? ????????????org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> ?? ????</filter> ????????<filter-mapping> ??????????<filter-name>struts2</filter-name> ??????????<url-pattern>/*</url-pattern> ??????</filter-mapping> ??????<servlet> ??????????<servlet-name>JspSupportServlet</servlet-name> ??????????<servlet-class>org.apache.struts2.views.JspSupportServlet</servlet-class> ??????????<load-on-startup>1</load-on-startup> ??????</servlet> ??????<welcome-file-list> ??????????<welcome-file>login.action</welcome-file> ??????</welcome-file-list> ????</web-app>??
