更改实体中断项目中的属性

Question

我使用这个项目(https://github.com/royclarkson/spring-rest-service-oauth)作为我的项目服务器。但是我只是想在User类中添加一些属性，我还更改了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;

我还更改了导入。sql:

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，我得到这个错误:

为什么?我只是改变了User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。有我遗漏的构型吗?

更新

我把源代码放在这个zip文件中。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firstName)在hibernate数据库列中是不可接受的。要么你有

@NotEmpty
private String first_name;

或者显式定义列名

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

就像下面的例子:http://www.petrikainulainen.net/programming/spring-framework/spring-data-jpa-tutorial-part-two-crud/

更新:引用我问过的朋友

"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"。因此你看到了。你需要在开始的时候知道这一点编写SQL查询。"

我也在网上搜索了这个:Hibernate列名问题和https://www.genuitec.com/forums/topic/hibernate-generated-classes-don-t-keep-upper-case-letters/
