首先，定义一个freemarker模板，解析对象studentList

/freemarker/success.ftl

<html>

<body>

<#list studentList as student>

<tr>

<td>${student.name}</td>

<td>${student.sex}</td>

</tr>

</#list>

</table>

</body>

</html>

JavaBean

package model;

public class Student {

private String name;

private String sex;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

编写控制器：

package Action;

import java.util.ArrayList;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import model.Student;

import org.springframework.validation.BindException;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.AbstractCommandController;

/**

* @@org.springframework.web.servlet.handler.commonsattributes.PathMap("/home.mvc");

public class FreemarkerHomeController extends AbstractCommandController {

protected ModelAndView handle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, BindException arg3) throws Exception {

// TODO 自动生成方法存根

return null;

}

protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {

Student stu1=new Student();

stu1.setName("gaoxiang1");

stu1.setSex("male1");

Student stu2=new Student();

stu2.setName("gaoxiang2");

stu2.setSex("male2");

List a=new ArrayList();

a.add(stu1);

a.add(stu2);

System.out.println(a);

return new ModelAndView("success","studentList",a);

}
