mykit-excel插件是通用的Excel导出导出框架,旨在提供通用的Excel导入导出功能,支持以注解方式选择JavaBean中的部分字段导出,并提供注解指定Excel列标题和排序功能。
- mykit-excel-annotation: mykit-excel框架的注解模块,提供注解标识类中的哪些字段需要导出到Excel
- mykit-excel-common: mykit-excel框架的通用工具类,提供通用的工具模板
- mykit-excel-servlet: mykit-excel框架提供的Web模块,能够支持Web请求导出Excel
- mykit-excel-springmvc: mykit-excel框架提供的SpringMVC模块,能够支持Web请求导出Excel
- mykit-excel-test: mykit-excel框架提供的常规测试模块
- mykit-excel-springboot: mykit-excel框架提供的SpringBoot测试模块
测试常规导出Excel工具类的Java类为:io.mykit.excel.springboot.normal.export.TestExportExcelUtils
,直接运行该类即可。
测试注解导出Excel工具类的Java类为:io.mykit.excel.springboot.normal.export.TestExportExcelUtils
,直接运行该类即可。
测试SpringMVC导出Excel的Java类为io.mykit.excel.springboot.normal.springmvc.NormalExportExcelContorller
,运行SpringBoot的启动类io.mykit.excel.springboot.MykitExcelCoreApplication
之后,使用resources/html目录下的normalExportExcel.html文件导出Excel即可。如果设置的IP和端口与mykit-excel-springboot模块不同,则修改normalExportExcel.html文件中的IP和端口即可。
测试基于注解导出Java类为io.mykit.excel.springboot.annotation.springmvc.AnnotationExportExcelController
,运行SpringBoot的启动类io.mykit.excel.springboot.MykitExcelCoreApplication
之后,使用resources/html目录下的annotationExportExcel.html文件导出Excel即可。如果设置的IP和端口与mykit-excel-springboot模块不同,则修改annotationExportExcel.html文件中的IP和端口即可。
如果使用注解方式导出Excel,则需要在JavaBean的属性字段上添加@ExcelColumn
注解,此注解中有三个属性,分别如下:
- isExport:表示是否将当前字段导出到Excel,true:是;false:否
- title:导出到Excel时的当前列的标题;
- sort:当前字段导出到Excel的列时,在Excel中的位置,值越小,当前列越靠前。
如果是普通的Java项目,只是将Excel文件导出到本地磁盘,则只需要在项目的pom.xml文件中增加如下配置
<dependency>
<groupId>io.mykit.excel</groupId>
<artifactId>mykit-excel-common</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
创建测试JavaBean
@Data
public class Student implements Serializable {
private static final long serialVersionUID = -2987207599880734028L;
private int id;
private String name;
private String sex;
public Student(){
}
public Student(int id, String name, String sex){
this.id = id;
this.name = name;
this.sex = sex;
}
}
接下来,在程序中按照如下方式导出Excel文件即可
public static void main(String[] args) throws Exception{
ExportExcelUtils<Student> utils = new ExportExcelUtils<Student>();
List<Student> list = new ArrayList<Student>();
for (int i = 0; i < 10; i++) {
list.add(new Student(111,"张三","男"));
list.add(new Student(111,"李四","男"));
list.add(new Student(111,"王五","女"));
}
String[] columnNames = { "ID", "姓名", "性别" };
utils.exportExcel("用户导出", columnNames, list, new FileOutputStream("E:/test.xls"), ExportExcelUtils.EXCEL_FILE_2003);
}
如果是普通的Java项目,以注解方式将Excel文件导出到本地磁盘,则只需要在项目的pom.xml文件中增加如下配置
<dependency>
<groupId>io.mykit.excel</groupId>
<artifactId>mykit-excel-common</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
创建测试JavaBean
(1) 创建父类JavaBean
@Data
public class Person implements Serializable {
private static final long serialVersionUID = 3251965335162340137L;
@ExcelColumn(isExport = true, title = "编号", sort = 2)
private String id ;
@ExcelColumn(isExport = true, title = "姓名", sort = 3)
private String name;
public Person(){
}
public Person(String id, String name){
this.id = id;
this.name = name;
}
}
(2) 创建子类JavaBean
@Data
public class Student extends Person{
private static final long serialVersionUID = -6180523202831503132L;
@ExcelColumn(isExport = false, title = "班级编号", sort = 1)
private String classNo;
private Integer score;
@ExcelColumn(isExport = true, title = "爱好", sort = 5)
private String hobby;
public Student(){
}
public Student(String id, String name, String classNo, Integer score, String hobby){
super(id, name);
this.classNo = classNo;
this.score = score;
this.hobby = hobby;
}
}
接下来,在程序中按照如下方式导出Excel文件即可
public class TestAnnotationExportExcelUtils {
public static void main(String[] args) throws FileNotFoundException {
// 准备数据
List<Student> list = new ArrayList<Student>();
for (int i = 1; i <= 10; i++) {
list.add(new Student("00" + i, "张三", "001", 100, "篮球"));
}
AnnotationExcelExportUtils<Student> utils = new AnnotationExcelExportUtils<Student>();
utils.exportExcel("用户导出", list, new FileOutputStream("e:/E:/test.xls"), Student.class, AnnotationExcelExportUtils.EXCEL_FILE_2003);
}
}
如果是基于Java Web或Spring MVC项目,需要导出Excel,则需要在项目的pom.xml文件中,加入如下配置
<dependency>
<groupId>io.mykit.excel</groupId>
<artifactId>mykit-excel-servlet</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>

@Data
public class Student implements Serializable {
private static final long serialVersionUID = -2987207599880734028L;

private String name;
private String sex;
public Student(){
}
public Student(int id, String name, String sex){
this.id = id;
this.name = name;
this.sex = sex;
}
}
接下来,在程序中按照如下方式导出Excel文件即可
@RequestMapping("/excel")
public void getExcel(HttpServletRequest request, HttpServletResponse response) throws Exception {
// 准备数据
List<Student> list = new ArrayList<Student>();
for (int i = 0; i < 10; i++) {
list.add(new Student(111,"张三","男"));
list.add(new Student(111,"李四","男"));
list.add(new Student(111,"王五","女"));
}
String[] columnNames = { "ID", "姓名", " 性别"};
String fileName = "springboot_excel";
ExportExcelWrapper<Student> util = new ExportExcelWrapper<Student>();
util.exportExcel(fileName, fileName, columnNames, list, response, ExportExcelUtils.EXCEL_FILE_2003);
}
如果是基于Java Web或Spring MVC项目,需要基于注解导出Excel,则需要在项目的pom.xml文件中,加入如下配置

前端测试代码放在mykit-excel-springboot模块的src/main/resources/html
目录下,修改html文件中的连接地址后,将其放在Tomcat或其他Web容器中,进行测试即可。
直接运行mykit-excel-springboot项目中的io.mykit.excel.springboot.normal.export.TestExportExcelUtils类即可
直接运行mykit-excel-springboot项目中的io.mykit.excel.springboot.annotation.export.TestAnnotationExportExcelUtils类即可
启动mykit-excel-springboot项目,即运行mykit-excel-springboot项目中的io.mykit.excel.springboot.MykitExcelCoreApplication类, 将mykit-excel-springboot项目的src/main/resources/html下的normalExportExcel.html文件发布到Tomcat等Web容器中访问normalExportExcel.html文件的连接地址, 打开页面点击“Submit”按钮即可。
