Java 在SpringMVC中生成XML响应

我有一个控制器类，我希望它显示用@XmlRootElement注释的模型类的.xml响应。显示所有学员列表的控制器类方法是

@RequestMapping("studentlist")  
   public @ResponseBody  
   StudentList getStudentList() {  
   List<student> studentList = new ArrayList<student>();  
   studentList.add(new Student(3, "Robert", "Parera", "robert@gmail.com", "88"));  
   studentList.add(new Student(93, "Andrew", "Strauss","andrew@gmail.com", "89"));  
   studentList.add(new Student(239, "Eddy", "Knight", "knight@gmail.com",  "79"));  
   return new StudentList(studentList);  
 }  

}

请告诉我缺少什么。我还有一个模型类，它用@XMLElement、@XmlRootElement等进行了适当的注释。由于我是Spring MVC的新手，敬请告知。

首先，您在XML中指定了Spring 3.0。第二，描述正在发生的事情：您是否得到了错误的输出？错误消息？我只是得到简单的响应，而不是xml，输出如下3RobertParerarobert@gmail.com4AndrewStrauss8978767878You请注意，您已经使用JAXB注释对模型类进行了注释。StudentList类也是这样吗？是的，它是一个带注释的模型类@XmlRootElementname=student list公共类StudentList{private list StudentList；protected StudentList{}public StudentList StudentList{this.StudentList=StudentList；}@javax.xml.bind.annotation.xmlementname=student public List getStudentList{return studentList；}
