从昨天开始我就遇到了这个错误，即使我已经尝试了所有想到的东西或者我在互联网上找到了搜索，我也无法解决它。上下文：java 6、Spring 3.1.4、camel 2.11.1、Oracle 驱动程序 10.2.0.2。

我在骆驼上下文文件中有这个bean：

<bean id="myDataSource"  class="**org.springframework.jdbc.datasource.DriverManagerDataSource**">
  <property name="driverClassName" value="**oracle.jdbc.driver.OracleDriver"**/>
  <property name="url" value="jdbc:...."/>
  <property name="username" value="userhere"/>
  <property name="password" value="passwordhere"/>
</bean>

我也尝试过使用这个 bean 的类： class=" org.apache.commons.dbcp.BasicDataSource " 以及在其他地方使用这个 bean 的 bean。我在 POM 中有这个（顺便说一下，我从另一个指向同一个数据库的项目中带来了这个依赖项，所以它是正确的版本）：

<dependency>
  <groupId>com.oracle</groupId>
  <artifactId>ojdbc14</artifactId>
  <version>10.2.0.2</version> 
  <scope>provided</scope>
</dependency>

我也有这个，因为我试图让它发挥作用：

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-jdbc</artifactId>
  <version>2.11.1</version>
</dependency>   
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-jdbc</artifactId>
  <version>3.1.4.RELEASE</version>
</dependency>
<dependency>
  <groupId>commons-dbcp</groupId>
  <artifactId>commons-dbcp</artifactId>
  <version>1.4</version>
</dependency>
  • 连接数据（url、用户和密码）已验证，并且对于我尝试连接的每个环境的数据库都是正确的。
  • 我可以在 Maven 依赖项中看到 ojdbc14 jar，在启用调试输出的情况下执行“maven run”时也看到它：[DEBUG] 添加项目依赖项工件：ojdbc14 to classpath
  • 我可以在 jar中看到类oracle.jdbc.driver.OracleDriver 。

然而，我每次都会遇到这些错误：

  • 当使用 class="org.apache.commons.dbcp.BasicDataSource" 作为数据源类时：class="org.apache.commons.dbcp.BasicDataSource"

    在这两条消息中，它显然无法加载 OracleDriver，尽管我不明白为什么。第一个是 ClassNotfoundException，第二个是 java.lang.IllegalStateException。

现在我在 Eclipse 中使用 maven 插件运行，我也尝试将 ojdbc jar 添加到 eclipse 类路径中，以防万一，但知道这不是使用 Maven 运行时的解决方案。但没有任何效果。oracle 驱动程序版本对于我们的 Orcale 是正确的，url 是正确的，所以用户和密码，我试图指向我可以访问的每个环境 db（本地、dev、qa、staging）。没有任何效果。

任何人都知道为什么它实际上将 jar 添加到类路径中时找不到或加载 OracleDriver？

您是否在应用程序服务器上运行此应用程序？如果服务器的类路径上没有 JDBC 驱动程序，请尝试将范围设置为 Oracle 驱动程序依赖项的默认（编译），因为它是默认值，您可以省略范围标记：

<dependency>
 <groupId>com.oracle</groupId>
 <artifactId>ojdbc14</artifactId>
 <version>10.2.0.2</version> 
</dependency>

两种范围的区别：

  • compile 这是默认范围，如果没有指定，则使用。编译依赖项在项目的所有类路径中都可用。此外，这些依赖关系会传播到依赖项目。
  • 提供 这很像编译，但表示您希望 JDK 或容器在运行时提供依赖项。例如，在为 Java 企业版构建 Web 应用程序时，您可以将 Servlet API 和相关 Java EE API 的依赖设置为提供的范围，因为 Web 容器提供了这些类。此范围仅在编译和测试类路径上可用，并且不可传递。

我正在使用不同版本的 oracle 驱动程序 (11.XXX)，但您可以尝试一下，看看它是否适用于：

<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close" lazy-init="true">
  <property name="dataSourceName" value="ds" />
  <property name="DriverType" value="{your_driver_type}" />
  <property name="user" value="{user}" />
  <property name="password" value="{password}" />
</bean>

我将此配置与 SQL 组件一起使用并且它可以工作，所以我想它应该对 Camel JDBC 工作相同。

是的，感谢您的解决方案。在我的情况下写“ compile”然后做**Maven更新项目工作**

问题：

PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' 抛出异常；嵌套异常是 java.lang.IllegalStateException：无法加载 JDBC 驱动程序类 [org.h2.Driver]

解决方案： 我写的范围H2 dependency如下然后右键单击Project-->Maven--> update Project 

 <dependency>
   <groupId>com.h2database</groupId>
   <artifactId>h2</artifactId>
   <version>1.4.195</version>
   <scope>compile</scope>
   </dependency>
