EasyPoi 动态修改表格标题名称
需求
代码实现
1、实体类
@Data@Accessors(chain = true)public class AccountVO implements Serializable {@Excel(name = "账户ID", orderNum = "2")private String accountId;@Excel(name = "账户名称", orderNum = "3")private String accountName;@Excel(name = "推广渠道", orderNum = "4")private String mediaPlatformName;@Excel(name = "品牌", orderNum = "5")private String brandNames;@Excel(name = "资金类型", orderNum = "6")private String fundTypeName;}
2、利用反射修改标题
// 获取目标实体类的目标字段Field field = AccountVO.class.getDeclaredField("brandNames");// 获取该字段的注解Excel annotation = field.getAnnotation(Excel.class);// 获取Excel注解所持有的 InvocationHandlerInvocationHandler handler = Proxy.getInvocationHandler(annotation);Field hFile = handler.getClass().getDeclaredField("memberValues");// 设值私有可访问hFile.setAccessible(true);Map<Object, Object> map = (Map<Object, Object>) hFile.get(handler);// 获取配置信息String barnd = environment.getProperty("config.brandAlias", "品牌");// 修改属性值map.put("name", barnd);
到此、即可动态的生成标题名称。
