Spring Roo管理实体：不可乐观锁定

2013-05-03 31 views 0 likes

有人知道如何禁用Spring Roo管理实体中的乐观锁定吗？我生成标注实体如下：Spring Roo管理实体：不可乐观锁定

@RooJavaBean 
@RooToString 
@RooJpaActiveRecord 
public class CoolDomain { 
}

然而，当我开始它未能线实体管理器应用程序说：

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)

为了避免版本检查我加入versionField=""属性@RooJpaActiveRecord注解。这解决了问题：

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