# easyexcel核心功能
## 目录
### 前言
-#### 关于@Data
-读写的对象都用到了[Lombok](https://www.projectlombok.org/),他会自动生成`get`,`set` ，如果不需要自己创建对象并生成`get`,`set` 。
#### 以下功能目前不支持
* 单个文件的并发写入、读取
* 读取图片
* 宏
* csv读取（这个后续可能会考虑）
+#### 常见问题
+* 关于@Data，读写的对象都用到了[Lombok](https://www.projectlombok.org/),他会自动生成`get`,`set` ，如果不需要的话，自己创建对象并生成`get`,`set` 。
+* 如果在读的时候`Listener`里面需要使用spring的`@Autowired`，给`Listener`创建成员变量，然后在构造方法里面传进去。而别必须不让spring管理`Listener`，每次读取都要`new`一个。
+* 如果用`String`去接收数字，出现小数点等情况，这个是BUG，但是很难修复，后续版本会修复这个问题。目前请使用`@NumberFormat`直接，里面的参数就是调用了java自带的`NumberFormat.format`方法，不知道怎么入参的可以自己网上查询。
#### 详细参数介绍
有些参数不知道怎么用，或者有些功能不知道用什么参数，参照：[详细参数介绍](/docs/API.md)
#### 开源项目不容易，如果觉得本项目对您的工作还是有帮助的话，请在右上角帮忙点个★Star。
