# 一、简介 #

在项目中，经常会有导出报表的需求，使用apache的POI自己需要写大量复杂的操作，因此使用easypoi来导出更为便捷

easypoi功能如同名字easy,主打的功能就是容易,让一个没见接触过poi的人员 就可以方便的写出Excel导出,Excel模板导出,Excel导入,Word模板导出,通过简单的注解和模板 语言(熟悉的表达式语法),完成以前复杂的写法

步骤：

1、引入依赖

2、创建javaBean并添加注解

3、添加数据，使用Easypoi工具类生成Workbook对象，存储为文件（导出）

# 二、引入依赖 #

<dependency>
                <groupId>cn.afterturn</groupId>
                <artifactId>easypoi-base</artifactId>
                <version>3.2.0</version>
            </dependency>
            <dependency>
                <groupId>cn.afterturn</groupId>
                <artifactId>easypoi-web</artifactId>
                <version>3.2.0</version>
            </dependency>
            <dependency>
                <groupId>cn.afterturn</groupId>
                <artifactId>easypoi-annotation</artifactId>
                <version>3.2.0</version>
            </dependency>
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.12</version>
                <scope>test</scope>
            </dependency>

#  三、创建javaBean并添加注解 #

package com.xiaomin;
    
    import cn.afterturn.easypoi.excel.annotation.Excel;
    
    /**
     * @author 晓敏
     * @create 2019-11-11 11:24
     */
    public class Student {
        @Excel(name = "序号")
        private int id;
        @Excel(name = "姓名")
        private String name;
        @Excel(name = "年龄")
        private int age;
        @Excel(name = "性别")
        private String sex;
    
        public Student(int id, String name, int age, String sex) {
            this.id = id;
            this.name = name;
            this.age = age;
            this.sex = sex;
        }
    
        public int getId() {
            return id;
        }
    
        public void setId(int id) {
            this.id = id;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
    
        public String getSex() {
            return sex;
        }
    
        public void setSex(String sex) {
            this.sex = sex;
        }
    }

# 四、添加数据，使用Easypoi工具类生成Workbook对象，存储为文件（导出） #

创建一个测试类

package com.xiaomin;
    
    import cn.afterturn.easypoi.excel.ExcelExportUtil;
    import cn.afterturn.easypoi.excel.entity.ExportParams;
    import org.apache.poi.ss.usermodel.Workbook;
    
    import java.io.FileOutputStream;
    import java.util.ArrayList;
    
    /**
     * @author 晓敏
     * @create 2019-11-11 11:28
     */
    public class TestExcel {
        public static void main(String[] args)throws Exception {
    
            Student s1 = new Student(1,"张三",21,"男");
            Student s2 = new Student(2,"李四",25,"女");
            Student s3 = new Student(3,"王五",22,"男");
            Student s4 = new Student(4,"赵六",24,"女");
            Student s5 = new Student(5,"钱孙",26,"男");
            Student s6 = new Student(6,"张九",18,"女");
    
            ArrayList list = new ArrayList();
            list.add(s1);
            list.add(s2);
            list.add(s3);
            list.add(s4);
            list.add(s5);
            list.add(s6);
    
            Workbook wb = ExcelExportUtil.exportExcel(new ExportParams("一班学生", "学生"), Student.class, list);
            //保存数据
            FileOutputStream outputStream = new FileOutputStream("D:\\student.xls");
            wb.write(outputStream);
            outputStream.close();
        }
    }
