struts2中使用freeMarker
1.在工程中导入struts2 jar包(里面已经包含了freeMarker的jar包)
2.TestAction.java
package com.test.struts2.action;
?
import com.opensymphony.xwork2.ActionSupport;
?
publicclass TestAction extends ActionSupport {
?
??? private String name;
?
??? @Override
??? public String execute() {
?????? return"success";
??? }
?
??? public String getName() {
?????? returnname;
??? }
?
??? publicvoid setName(String name) {
?????? this.name = name;
??? }
?
}
3.在WebContent目录下新建templates文件夹
4.在templates文件夹下新建result.ftl
<html>
? <head>
??? <title>My JSP 'index.jsp' starting page</title>
? </head>
? <body>
??? <h1>${name}</h1>
??? <@s.form action="reg" >
?????? <@s.textfield label="用户名" name="uname"? />
?????? <@s.submit />
??? </@s.form>
? </body>
</html>
5.struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
??? "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
??? "http://struts.apache.org/dtds/struts-2.3.dtd">
