原因: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:表'test.spring_session‘不存在- Spring
提问于 2016-08-29 16:57:22
我正在开发springboot-springsession-jdbc-demo。当我简单地运行代码时，我会得到以下错误。在我看来，有些属性必须在application.properties中设置，才能手工创建模式/表。所需的配置已经放置，但仍会产生错误。代码存在于https://github.com/sivaprasadreddy/spring-session-samples中。
供参考的错误：
org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [DELETE FROM SPRING_SESSION WHERE LAST_ACCESS_TIME < ?]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'test.spring_session' doesn't exist
