fremarker导出word list

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
