在实体中断项目中更改属性

Question

我正在使用这个项目 (https://github.com/royclarkson/spring-rest-service-oauth) 作为我项目的服务器。但是我只是想在User类里面添加一些属性，我也改了import.sql。我将“name”（也对 getter 和 setter 进行了重构）更改为“firstName”并添加了另一个“lastName”（并添加了各自的 getter 和 setter）。

@NotEmpty
private String firstName;
@NotEmpty
private String lastName;

而且我还把 import.sql 改成了：

insert into user(id, firstName, lastName, login, password) values (1,'Roy','Smith','roy','pass');

insert into user(id, firstName, lastName, login, password) values (2,'Craig','Jones','craig','pass');

insert into user(id, firstName, lastName, login, password) values (3,'Greg','Robinson','greg','pass');

然后当我运行我的测试用例时，它们都失败了！例如，如果我在 GreetingControllerTest.java 中运行“greetingAuthorized”测试用例，我会收到以下错误：

为什么？我只是更改了用户中的一些属性，我的测试用例无法运行。我确实重新启动了服务器。有没有我遗漏的配置？

更新

我将我的源代码放在this zip file 中。此版本仅将“name”更改为“firstName”，问题就出现了。

Answer 1

这是因为大写字母（例如名字）在休眠数据库列中是不可接受的。要么你拥有它

@NotEmpty
private String first_name;

或者你明确定义列名

@Column(name = "first_name", nullable = false)
private String firstName;

就像这个例子：http://www.petrikainulainen.net/programming/spring-framework/spring-data-jpa-tutorial-part-two-crud/

更新：引用我问过的朋友的话

“大多数数据库都有不区分大小写的对象名称，所以大写 字母没有意义。 Hibernate 将大写字母转换为 '_ + small 信'。因此你所看到的。开始时你需要知道这一点 编写 SQL 查询。”

我也在网上搜索过这个： hibernate column name issues 和 https://www.genuitec.com/forums/topic/hibernate-generated-classes-don-t-keep-upper-case-letters/
