我的环境是Spring 4.0.5，hibernate 4.3.6，hsql 2.3.2。在生产中它将连接到MySQL。HSQL中的@GeneratedValue（strategy = GenerationType.IDENTITY）不会自动生成主键
原来的实体类注释这样
@Id
@Column(name = "sid", nullable = true)
private Long sid;
然后是AUTO_INCREMENT主键列我尝试将其修正为
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "sid", nullable = false)
private Long sid;
但在测试环境中，我使用org.hibernate.tool.hbm2ddl.SchemaExport与config.setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");出口模式，但我不能坚持这个类，因为它抱怨它违反了NOT NULL约束。
但是，当我做了搜索，所有文章都说GenerationType.IDENTITY是由MySql和HSQLDB支持的，还有其他原因可能会失败吗？
==========生成模式============
private void generateSchema() {
final SchemaExport export = new SchemaExport(getConfig());
export.setDelimiter(";");
export.create(true, true);
}
private Configuration getConfig() {
final Configuration config = new Configuration();
config.addAnnotatedClass(A.class);
config.addAnnotatedClass(B.class);
...
config.setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
config.setProperty("hibernate.connection.driver_class", "org.hsqldb.jdbc.JDBCDriver");
config.setProperty("hibernate.connection.url", getUrl());
config.setProperty("hibernate.connection.username", "SA");
config.setProperty("hibernate.connection.password", "");
return config;
}
============== =更新堆栈跟踪===========

它只有没有空约束，但没有任何与自动增量有关。但是我不知道为什么GenerateType.IDENTITY没有做任何事情。此表不会与其他人一起加入，因此没有@OneToMany或此类别中的其他人
什么是失败，它是如何失败？发布相关代码和堆栈跟踪。向我们展示如何定义关联的表。 –
是否有另一个'nullable = false'属性？你也可以摆脱@Column注释。 – lametaweb
@lametaweb：否那个列只有一个可为空= false。 –
