奇怪的grails错误用户错误

Question

我使用没有数据库的Grails和Spring Security LDAP。它工作正常，但现在突然正在做

HTTP Status 500 - could not execute query;
SQL [select this_.id as id2_0_, this_.version as version2_0_, this_.account_expired as account3_2_0_, this_.account_locked as account4_2_0_, this_.enabled as enabled2_0_, this_."password" as password6_2_0_, this_.password_expired as password7_2_0_, this_.username as username2_0_ from user this_ where (this_.username=?)];
nested exception is org.hibernate.exception.SQLGrammarException: could not execute query

知道这是从哪里来的吗？我已尝试执行grails clean并执行grails RefreshDependencies。
