Question

有人知道如何在Spring Roo托管实体中禁用乐观锁定吗？我生成的实体注释如下：

@RooJavaBean
@RooToString
@RooJpaActiveRecord
public class CoolDomain {
}

然而，当我启动应用程序时，它无法连接实体经理说：

Caused by: org.hibernate.HibernateException: Missing column: version in COOL_DOMAIN
    at org.hibernate.mapping.Table.validateColumns(Table.java:369)
    at org.hibernate.cfg.Configuration.validateSchema(Configuration.java:1275)
    at org.hibernate.tool.hbm2ddl.SchemaValidator.validate(SchemaValidator.java:155)

为避免版本检查，我将versionField=""属性添加到@RooJpaActiveRecord注释。这解决了这个问题：

@RooJavaBean
@RooToString
@RooJpaActiveRecord(versionField="")
public class CoolDomain {
}
