使用Hutool导出Excel并合并单元格的步骤如下:
1. 导入相关依赖:
```xml
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.7.9</version>
</dependency>
```
2. 创建ExcelWriter对象:
```java
ExcelWriter writer = ExcelUtil.getWriter("D:/test.xlsx");
```
3. 写入表头:
```java
writer.merge(0, "测试报表", true);
writer.writeHeadRow(Arrays.asList("姓名", "年龄", "性别"));
```
4. 写入数据:
```java
List<User> userList = getUserList();
for (User user : userList) {
writer.writeRow(Arrays.asList(user.getName(), user.getAge(), user.getGender()));
}
```
5. 合并单元格:
```java
writer.merge(1, 1, 0, 2, "统计信息", true);
```
其中,参数1和参数2分别是要合并的起始行和列,参数3和参数4分别是要合并的结束行和列,参数5是要合并的内容。
6. 关闭ExcelWriter:
```java
writer.close();
```
完整代码示例:
```java
public static void exportExcel() {
ExcelWriter writer = ExcelUtil.getWriter("D:/test.xlsx");
writer.merge(0, "测试报表", true);
writer.writeHeadRow(Arrays.asList("姓名", "年龄", "性别"));
List<User> userList = getUserList();
for (User user : userList) {
writer.writeRow(Arrays.asList(user.getName(), user.getAge(), user.getGender()));
}
writer.merge(1, 1, 0, 2, "统计信息", true);
writer.close();
}
private static List<User> getUserList() {
List<User> userList = new ArrayList<>();
userList.add(new User("张三", 23, "男"));
userList.add(new User("李四", 25, "女"));
userList.add(new User("王五", 28, "男"));
return userList;
}
@Data
@AllArgsConstructor
@NoArgsConstructor
public static class User {
private String name;
private Integer age;
private String gender;
}
```
注意,这里的示例代码仅供参考,具体实现还需要根据实际情况进行调整。
