SpringCloud+JDK17整合EaseExcel记录
在JDK7下,使用easyexcel批量导出excel可以按照以下步骤进行:
1. 在pom.xml文件中添加easyexcel的依赖,例如:
```xml
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easyexcel</artifactId>
<version>2.1.6</version>
</dependency>
```
2. 创建ExcelWriter并设置相关参数,例如:
```java
OutputStream out = new FileOutputStream("test.xlsx");
ExcelWriter writer = new ExcelWriter(out, ExcelTypeEnum.XLSX, true);
```
3. 创建Sheet并写入数据,例如:
```java
Sheet sheet = new Sheet(1, 0, MyModel.class);
List<MyModel> data = getData();
writer.write(data, sheet);
```
其中,MyModel是需要导出的数据模型,getData()是获取数据的方法。
4. 完成导出并关闭ExcelWriter,例如:
```java
writer.finish();
out.close();
```
完整的代码示例:
```java
public class ExcelUtil {
public static void writeExcel() throws Exception {
OutputStream out = new FileOutputStream("test.xlsx");
ExcelWriter writer = new ExcelWriter(out, ExcelTypeEnum.XLSX, true);
Sheet sheet = new Sheet(1, 0, MyModel.class);
List<MyModel> data = getData();
writer.write(data, sheet);
writer.finish();
out.close();
}
private static List<MyModel> getData() {
// TODO: 获取数据
}
private static class MyModel {
// TODO: 数据模型
}
}
```
