POI-tl 知识整理：整理1 -＞ 利用模板向word中写入数据

1 文本传值

    @Test
    public void testText() throws Exception {
        XWPFTemplate template = XWPFTemplate.compile("D:\\Idea-projects\\POI_word\\templates.docx");
        Map<String, Object> map = new HashMap<>();
        map.put("title", "Hi, girl");
        template.render(map);

        FileOutputStream fileOutputStream = new FileOutputStream("D:\\Idea-projects\\POI_word\\output.docx");
        template.writeAndClose(fileOutputStream);

        template.close();
    }

2 对象传值

public class Student {
    private  String name;
    private  int age;
    private  String sex;

    // getter and setter

}

    @Test
    public void testObject() throws Exception{
        // 数据可以是对象
        Student student = new Student();
        student.setName("小蟹");
        student.setAge(20);
        student.setSex("男");

        XWPFTemplate template = XWPFTemplate.compile("D:\\Idea-projects\\POI_word\\templates1.docx");
        Map<String, Object> map = new HashMap<>();
        map.put("name", student.getName());
        map.put("age", student.getAge());
        map.put("sex", student.getSex());
        template.render(map);

        FileOutputStream fileOutputStream = new FileOutputStream("D:\\Idea-projects\\POI_word\\output_object.docx");
        template.writeAndClose(fileOutputStream);

        template.close();
    }

3 Map 传值

    // Map 传值
    @Test
    public void testMapping() throws Exception{
        // 数据可以是Map集合
        Map<String, Object> data = new HashMap<>();
        data.put("name", "小草");
        data.put("age", 22);
        data.put("sex", "女");

        XWPFTemplate template = XWPFTemplate.compile("D:\\Idea-projects\\POI_word\\templates1.docx");

        Map<String, Object> map = new HashMap<>();
        map.put("map", data);
        XWPFTemplate render = template.render(map);

        FileOutputStream fileOutputStream = new FileOutputStream("D:\\Idea-projects\\POI_word\\output_map.docx");
        template.writeAndClose(fileOutputStream);

        template.close();  // 一定要记得关闭
    }
