使用Oracle for jhipster应用程序时无法初始化数据库

Question

我正在尝试使用Oracle数据库在生产模式下进行jhipster开发。

profiles:
    active: prod
datasource:
    driverClassName: oracle.jdbc.OracleDriver
    dataSourceClassName: oracle.jdbc.pool.OracleDataSource
    url: jdbc:oracle:thin:@127.0.01:49161:xe
    databaseName:
    serverName: 
    username: vpp_owner
    password: vpp_owner

jpa:
    database-platform: org.hibernate.dialect.Oracle10GDialect
    database: ORACLE
    openInView: false
    show_sql: true
    generate-ddl: false
    hibernate:
        ddl-auto: none
        naming-strategy: org.hibernate.cfg.EJB3NamingStrategy
    properties:
        hibernate.cache.use_second_level_cache: true
        hibernate.cache.use_query_cache: false
        hibernate.generate_statistics: false
        hibernate.cache.region.factory_class: org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

Oracle服务器已启动并运行，我能够使用给定的凭据连接到数据库。在运行mvn -Pprod mvn-boot之后，我得到了以下SQLException

问题似乎出在默认的SEQ_USER.NEXTVAL NOT NULL表达式上。

我使用的是jhipster 2.19.0和Oracle 11g。

Answer 1

对于Oracle 11g，这是不可能的。

来自这里的文档：http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_7002.htm#sthref7262

DEFAULT表达式不能包含对PL/SQL函数或其他列、伪列CURRVAL、NEXTVAL、LEVEL、PRIOR和ROWNUM或未完全指定的date常量的引用。

此类语句仅适用于Oracle 12c或更高版本：

https://oracle-base.com/articles/12c/default-values-for-table-columns-enhancements-12cr1

Answer 2

当我对生成的源代码应用一些更改时，我能够使用11G数据库。

1. In User.java将id字段的GenerationType.SEQUENCE替换为GenerationType.AUTO。der liquibase文件中的
2. 删除所有id字段的defaultValueComputed属性。
3. 删除表的特定序列
4. 不从“hibernate_sequence”changelog中删除代码；-)

这是否可以包含在jhipster生成器中？

Answer 3

正如@Moh-Aw所说，它可以与Oracle 12c或更高版本一起使用。对于不支持计算默认值的早期版本，您可以使用触发器。这里有一个补丁
