java.sql.SQLException：没有合适的驱动程序无法为连接 URL 创建类“oracle.jdbc.driver.OracleDriver”的 JDBC 驱动程序

Question

我正在尝试使用 TNS URL、用户名和密码连接到 Oracle 11i 数据库。 JNDI 正在成功查找数据源，但我无法获取连接。相反，我看到了以下堆栈跟踪。

我的 Maven 设置如下。

    <dependency>
        <groupId>ojdbc</groupId>
        <artifactId>ojdbc</artifactId>
        <version>6</version>
    </dependency>   

我的 Spring MVC 应用程序已部署到 Tomcat 8。我在 $CATALINA_HOME/lib 位置有 oracle jar 文件。我在$CATALINA_HOME/conf/context.xml 中的 JNDI 配置如下所示

<Resource name="jdbc/myDB" auth="Container" type="javax.sql.DataSource" username="username" password="password" driverClassName="oracle.jdbc.driver.OracleDriver" url="Jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=<host_name>)(PORT=49125))(CONNECT_DATA=(SERVER=DEDICATED)(service_name=<service_name>)))" maxTotal="10" maxIdle="5"  poolPreparedStatements="true"  validationQuery="select 1" />

我的 web.xml 配置

  <resource-ref>
  <description>
    Resource reference to a factory for java.sql.Connection
    instances that may be used for talking to a particular
    database that is configured in the  configuration for the web application.
  </description>
  <res-ref-name>
    jdbc/myDB
  </res-ref-name>
  <res-type>
    javax.sql.DataSource
  </res-type>
  <res-auth>
    Container
  </res-auth>
</resource-ref>

我不确定我做错了什么。我能够使用 DriverManager API 成功连接。我已阅读以下主题，但我无法弄清楚我做错了什么。我已经尝试了接受的解决方案中的所有建议，但无济于事。

1. java.sql.SQLException: No suitable driver found jdbc:oracle:thin
2. java.sql.SQLException: No suitable driver
3. Cannot create JDBC driver of class '' for connect URL 'null'

Answer 1

您的 Maven 设置看起来有问题。请试试这个：

<dependency>
 <groupId>com.oracle.jdbc</groupId>
 <artifactId>ojdbc6</artifactId>
 <version>11.2.0.4</version>
</dependency>
