我正在从运行在 tomcat 中的 Web 应用程序连接到在 Linux 机器上运行的 MySQL (5.08) 数据库。
尝试执行存储过程时出现以下异常:
com.hp.hpl.chaos.web.exception.DBException: getNextValue for operatorinstance[Additional Information from SQL Exception][SQLErrorCode: 0 SQLState: S1000

Caused by: java.sql.SQLException: User does not have access to metadata required to determine stored procedure parameter types. If rights can not be granted, configure connection with "noAccessToProcedureBodies=true" to have driver generate parameters that represent INOUT strings irregardless of actual parameter types.

在机器上安装mysql之后。我已将以下授予选项授予 root
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'pass';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
在java类..
我按如下方式连接到数据库:
String url = "jdbc:mysql://ipaddress:3306/test";
con = DriverManager.getConnection(url,"root", "pass");
我还尝试了noAccessToProcedureBodies=true
包含选项的 url。
有人可以告诉我这里有什么问题吗?有什么我需要检查的吗?
