使用

public void createReport(){
    Map<String, Object> dataMap = this.getDataMap();
    String modelFileName = "/world.ftl";
    String fileName = "D:\Myworkspace\Myeclipse\数据报表。doc";
    FreemarkerWordUtils wordUtils = new FreemarkerWordUtils(modelFileName, descFileName, fileName);
    File file = wordUtils.createDoc();
}
