1.我们要写一个注解ExcelField类。
@Target({ElementType.METHOD, ElementType.FIELD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface ExcelField {
/**
* 导出字段名（默认调用当前字段的“get”方法，如指定导出字段为对象，请填写“对象名.对象属性”，例：“area.name”、“office.name”）
*/
String value() default "";
/**
* 导出字段标题（需要添加批注请用“**”分隔，标题**批注，仅对导出模板有效）
*/
String title();
/**
* 字段类型（0：导出导入；1：仅导出；2：仅导入）
*/
int type() default 0;
/**
* 导出字段对齐方式（0：自动；1：靠左；2：居中；3：靠右）
*/
int align() default 0;
/**
* 导出字段字段排序（升序）
*/
int sort() default 0;
/**
* 如果是字典类型，请设置字典的type值
*/
String dictType() default "";
/**
* 反射类型
*/
Class<?> fieldType() default Class.class;
/**
* 字段归属组（根据分组导出导入）
*/
int[] groups() default {};
