* 单个文件的并发写入、读取
* 读取图片
* 宏
ClassNotFoundException与java.lang.NoClassDefFoundError的区别
* 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` 。
* 出现`NoSuchMethodException`,`ClassNotFoundException`,`NoClassDefFoundError`极大概率是jar冲突,建议`clean`项目,或者统一`poi` 的版本,理论上来说`easyexcel`兼容poi的`3.17`,`4.0.1`,`4.1.0`所有较新版本
* 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
