使用Easypoi生成复杂Excel需要以下步骤:
1. 引入Easypoi的Maven依赖
```xml
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-base</artifactId>
<version>5.1.0</version>
</dependency>
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-annotation</artifactId>
<version>5.1.0</version>
</dependency>
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-web</artifactId>
<version>5.1.0</version>
</dependency>
```
2. 创建JavaBean作为Excel的数据模型,并使用Easypoi的注解进行配置,例如:
```java
public class User {
@Excel(name = "姓名", orderNum = "0")
private String name;
@Excel(name = "年龄", orderNum = "1")
private Integer age;
@Excel(name = "性别", orderNum = "2", replace = {"男_1", "女_2"})
private Integer gender;
// 省略getter和setter方法
}
```
3. 创建Excel导出的控制器,并使用Easypoi提供的API生成Excel文件,例如:
```java
@RestController
@RequestMapping("/excel")
public class ExcelController {
@GetMapping("/export")
public void export(HttpServletResponse response) throws IOException {
List<User> userList = new ArrayList<>();
userList.add(new User("张三", 20, 1));
userList.add(new User("李四", 25, 1));
userList.add(new User("王五", 30, 2));
ExportParams exportParams = new ExportParams("用户信息", "用户");
Workbook workbook = ExcelExportUtil.exportExcel(exportParams, User.class, userList);
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("用户信息.xlsx", "UTF-8"));
workbook.write(response.getOutputStream());
}
}
```
4. 使用Easypoi的其他特性,如自定义样式、合并单元格、图片导出等,进行Excel的定制化开发。
Easypoi具有较高的灵活性和可扩展性,可以满足大部分复杂Excel的生成需求。
