仅带方法：
public void export() {
        Map<String, List<Student>> dataMap = new HashMap<String, List<Student>>();
        List<Student> list = new ArrayList<Student>();
        for(int a = 0; a < 5; a++){
            Student s = new Student(a, "stuNo" + a, "name"+a, "age"+a, "class"+a);
            list.add(s);
        }
        dataMap.put("students", list);

        // 设置配置文件Configuration 此类的创建为单例模式
        Configuration configuration = new Configuration(Configuration.VERSION_2_3_22);
        configuration.setDefaultEncoding("UTF-8");
        configuration.setClassForTemplateLoading(this.getClass(), "/com/haiyisoft/iecp/dw/dd/action");

        // 获取系统属性名称、系统分割符
        Properties properties = System.getProperties();
        String osName = properties.getProperty("os.name");
        String separator = properties.getProperty("file.separator");
        System.out.println(osName + "文件目录分隔符：" + separator);

        // 获取文件导出路径（默认发布项目下download目录中）
        //HttpServletRequest request = ServletActionContext.getRequest();
        //String urlStr = request.getSession().getServletContext().getRealPath("/") + "download\\";
        //urlStr = urlStr.replace("\\", "/");
        // 桌面路径
        String urlStr = FileSystemView.getFileSystemView() .getHomeDirectory().getAbsolutePath();
        String fileName = "test.doc";
        //设置输出文件  输出流  写入类  模板
        File outFile = new File(urlStr + "/" + fileName);
        FileOutputStream outputStream = null;
        Writer writer = null;
        Template template = null;
        try {
            template = configuration.getTemplate("temp.ftl");
            outputStream = new FileOutputStream(outFile);
            writer = new OutputStreamWriter(outputStream, "UTF-8");
            template.process(dataMap, writer);
            writer.close();
            outputStream.close();
        } catch (Exception e) {
            System.out.println("出错啦！！！！");
            e.printStackTrace();
        }
    }

// 此为实体类student

public class Student {
	private int id;
	private String stuNo;
	private String name;
	private String age;
	private String classes;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getStuNo() {
		return stuNo;
	}
	public void setStuNo(String stuNo) {
		this.stuNo = stuNo;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	public String getClasses() {
		return classes;
	}
	public void setClasses(String classes) {
		this.classes = classes;
	}
	public Student(int id, String stuNo, String name, String age, String classes) {
		super();
		this.id = id;
		this.stuNo = stuNo;
		this.name = name;
		this.age = age;
		this.classes = classes;
	}

}

这里只写方法。。
插入list类似于下列类型，将学生信息依次导入，其中${student.stNo!””}为表格中变量，student中变量需与上述实体类中变量对应

模板文件中没有自带list，需手动添加
