Spring Session JDBCTokenRepository覆盖默认表

问题描述

我设置了Spring的会话“记住我”选项，并使用JdbcTokenRepositoryImpl作为Spring Session的PersistentTokenRepository。不幸的是，开发人员对表“ persistent_logins”的名称进行了硬编码，这不适用于我的应用程序，并且不能在Oracle中使用（因为它需要在SQL查询中指定架构名称）。

问题是：哪个是将默认表名“ persistent_logins”覆盖到另一个的最简单方法？

在这里进行了一些搜索之后，我发现可以重写JdbcTokenRepositoryImpl。但是不幸的是，仅覆盖SQL字符串（请参见下面的代码）无法正常工作。

更新：所以我从这里获取了原始源代码：https://github.com/spring-projects/spring-security/blob/master/web/src/main/java/org/springframework/security/web/authentication/rememberme/JdbcTokenRepositoryImpl.java现在它可以工作了，但是我怀疑这是否是一个最佳解决方案，因为原始库中的任何更改都会使我的代码崩溃。
