java自定义注解在excel导出时的使用

自定义注解：

@Documented@Target({ElementType.METHOD,ElementType.FIELD})@Retention(RetentionPolicy.RUNTIME)public @interface ExcelColumn {    String name() default "zhoushun";}

注解类：

public class ActivityDataDetailBean implements Serializable {    private static final long serialVersionUID = 7689111063501975678L;    @ExcelColumn(name="活动ID")    private int activityId;    @ExcelColumn(name = "日期")    private String date;    @ExcelColumn(name = "城市")    private String cityName;    @ExcelColumn(name = "投放位置")    private String slot;    @ExcelColumn(name="pageId")    private String topicId;    @ExcelColumn(name = "页面PV")    private Long pv;    @ExcelColumn(name = "页面UV")    private Long uv;    @ExcelColumn(name = "页面点击数")    private Long click;    @ExcelColumn(name="页面到达率")    private String reachRate;    @ExcelColumn(name = "页面关闭率")    private String closeRate;    @ExcelColumn(name = "分享量")    private Long shareCount;

导出时获取注解内容：

 private static void getReflectInfo(Class<?> c,List<String> head,List<Method> getMethod) throws IntrospectionException {        Field[] fields = c.getDeclaredFields();        for (int i = 0; i < fields.length; i++) {            if (!fields[i].getName().equalsIgnoreCase("serialVersionUID") && !fields[i].getName().equalsIgnoreCase("$jacocoData")) {                ExcelColumn excelColumns = fields[i].getAnnotation(ExcelColumn.class);                if (excelColumns != null) {                    head.add(excelColumns.name());                } else {                    head.add(fields[i].getName());                }                getMethod.add(new PropertyDescriptor(fields[i].getName(), c).getReadMethod());            }        }    }
