首先，定义一个freemarker模板，解析对象studentList
/freemarker/success.ftl
<html>
<body>
<table border="1">
<#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);
}
}
