问题描述
我正在尝试配置Sniffy以与Oracle合作。我使用Glassfish作为应用程序服务器，使用JPA 2.0，使用EclipseLink作为提供程序。
I'm trying to configure Sniffy to work with Oracle. I'm using Glassfish as application server, with JPA 2.0, and EclipseLink as provider.
当EclipseLink尝试分配连接时，它无法说明指定的Oracle URL是无效，因为sniffer：前缀，我想：
When EclipseLink tries to allocate the connection, it fails saying that the Oracle URL specified is invalid, because of the "sniffer:" prefix, I guess:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed;
nested exception is javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: Invalid Oracle URL specified
Error Code: 0
这是我在domain.xml文件中配置池的方式：
This is how I configured the pool in my domain.xml file:
<jdbc-resource pool-name="poolGI" object-type="system-all" jndi-name="jdbc/poolGI" />
<jdbc-connection-pool driver-classname="io.sniffy.MockDriver" name="poolGI" res-type="javax.sql.DataSource" datasource-classname="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="sniffer:jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=host1)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=host2)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=service)))"></property>
<property name="user" value="user"></property>
<property name="password" value="password"></property>
</jdbc-connection-pool>
推荐答案
开发人员。
看起来像 oracle.jdbc.pool.OracleDataSource 忽略 driver-classname 属性并隐式使用 oracle.jdbc.driver.OracleDriver 。 OracleDriver不知道 sniffer：架构，因此异常。
Looks like oracle.jdbc.pool.OracleDataSource ignores the driver-classname property and implicitly uses oracle.jdbc.driver.OracleDriver. OracleDriver doesn't know about sniffer: schema, hence the exception.
您需要切换到另一个数据源为了使用Sniffy。
例如。
You need to switch to another data source in order to use Sniffy.For example Hikari Connection Pool.
