小编Sah*_*sar的帖子

我想用Dropwizard实现@Auditable。哪一个将创建* _audit表，并将详细信息与Revinfo表一起存储？

我正在将Dropwizard与Liquibase一起使用。

我在实体上添加了@Auditable

@Entity
@Table(name = "user_plan")
@Audited
public class UserPlan extends IdentityEntity

并尝试更新抛出错误的表

我在 Java 中使用 sendgrid 电子邮件。我正在尝试发送多个附件，但不知何故电子邮件丢失了 1 或 2 个文件。有时，所有附件都被发送。我也检查了状态码。每次都是202。这是不可预测的行为。谁能指出我是否遗漏了什么。
