JDBC连接MySql不需要再配置noAccessToProcedureBodies

针对以下错误：

"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."

不需要再配置noAccessToProcedureBodies=true了，更好的解决办法是：为连接MySql的这个数据库用户分配“获取存储过程元数据（MetaData）”的权限：

grant Select on mysql.proc to 'user'@%
