Spring jdbc 不适用于 h2 查询递归

Question

有标准的 tables 组和 ACL。我与 table 组建立了多对多连接，以便能够将该组包含在该组中。现在，当我尝试 Spring 安全性来替换使用 H2 数据库和请求类型的查询时

@Bean
public JdbcUserDetailsManager userDetailsManager() {
    JdbcUserDetailsManager manager = new JdbcUserDetailsManager();
    manager.setDataSource(dataSource);
    manager.setRolePrefix("GROUP_");
    manager.setEnableGroups(true);
    manager.setEnableAuthorities(false);
    manager.setGroupAuthoritiesByUsernameQuery(
            //h2
            "WITH recursive rec_groups (parent, child, name, authority) AS " +
                    "(SELECT gm.group_id, cast(NULL as bigint), g.group_name, ga.authority " +
                    "FROM wsseddb.group_members as gm, wsseddb.groups g, wsseddb.GROUP_AUTHORITIES as ga " +
                    "WHERE username = ? and g.id = gm.group_id and ga.group_id = gm.group_id " +
                    "UNION ALL " +
                    "SELECT gpc.parent_id, gpc.child_id, g.group_name, ga.authority " +
                    "FROM wsseddb.groups_parent_child as  gpc, rec_groups as rg, wsseddb.GROUPS  as g,  wsseddb.GROUP_AUTHORITIES as ga " +
                    "WHERE child_id = rg.parent and g.id = gpc.parent_id and ga.group_id = gpc.parent_id) " +
                    "SELECT gs.parent, gs.name as group_name, gs.authority FROM rec_groups gs");
    return manager;
}`

我不回来列出GrandedAuthority。当我使用 postgresql 时，一切正常。如何用h2解决这个问题？

在网络 H2 查询中工作正常但在 spring jdbc preparentstatement return 0 行中

Answer 1

There is a known bug in H2's implementation of recursive CTE. 。按照现在的情况（版本 1.4.191），如果您的递归 CTE 包含任何绑定变量，则执行不正确。如果您删除并内联绑定变量，它应该可以工作（当然要注意 SQL 注入）。

请注意，此功能是 experimental in H2
