Java EE 7 + 持久性 + 休眠:无法持久化数据



我是Spring Boot开发人员，目前正在尝试学习使用Java EE 7和JAX-RS的轻量级解决方案。我当前在尝试将数据从应用程序保存到数据库时遇到问题。任何关于我做错了什么的指示，不胜感激！

更新 1

数据库

CREATE TABLE users
(
user_id SERIAL NOT NULL CONSTRAINT users_pkey PRIMARY KEY,
user_email VARCHAR(255) NOT NULL
);

更新 2

Docker 命令复制我的数据库(手动制作表(

docker run --name jax-rs -e POSTGRES_PASSWORD=password -e POSTGRES_USER=user -e POSTGRES_DB=jax-rs -p 5432:5432 -d postgres

我已经发现我的问题是由于缺乏对 TomEE 在部署的应用程序中所扮演的角色的理解引起的。

这个答案解决了我的问题(在为 Postgres 调整后(

您输入了错误的表名，并将names放在user类中而不是user

@Table(name = "user", schema = "public", catalog = "jax-rs")
