利用注解解决字段中文显示问题

注解：columnHead

@Target({ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface ColumnHead {

    String key() default "";

    String title() default "";

    boolean show() default true;

    PropertyType type() default PropertyType.TEXT;
}

注解处理器 ColumnHeadResolver

        return getHeads(clazz, "");
    }

    public static List<PaginationVO.Head> getHeads(Class<?> clazz, String condition) {
        List<PaginationVO.Head> heads = new ArrayList<>();
        try {
            HashMap<String, Object> conditionMap = new HashMap<>();
            if (StringUtils.isNoneBlank(condition)) {
                String[] arrStr = condition.split(",");
                Arrays.stream(arrStr).forEach(item -> {
                    int index = item.indexOf(":");
                    conditionMap.put(item.substring(0, index).trim(), item.substring(index + 1).trim());
                });
            }
            Field[] fields = clazz.getDeclaredFields();
            for (Field f : fields) {
                ColumnHead head = f.getDeclaredAnnotation(ColumnHead.class);
                PaginationVO.Head h = new PaginationVO.Head();
                h.setKey(head.key());
                if (StringUtils.isBlank(head.key())) {
                    h.setKey(f.getName());
                }
                h.setTitle(head.title());
                h.setType(head.type());
                h.setShow(head.show());
                if (StringUtils.isNoneBlank(condition) && conditionMap.get(f.getName()) != null) {
                    String show = (String) conditionMap.get(f.getName());
                    if ("1".equalsIgnoreCase(show)) {
                        h.setShow(true);
                    } else {
                        h.setShow(false);
                    }
                }
                heads.add(h);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return heads;
    }
}

主要是利用注解可以动态设置字段的中文名，显示与否， 字段类型等相关属性
