Maven-Camel-Spring-Oracle：创建bean时出错-java.lang.IllegalStateException：无法加载JDBC驱动程序类[oracle.jdbc.driver
作者：互联网
从昨天开始,我就收到了这个错误消息,即使我已经尝试过所有想到的事情,或者发现在Internet上进行搜索,但仍无法解决.
上下文：Java 6,Spring 3.1.4,骆驼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>
我也尝试过使用此类的bean：class =“ org.apache.commons.dbcp.BasicDataSource”
还有一个在其他地方使用这个bean的bean.
我在POM中有这个(顺便说一句,我从另一个指向同一数据库的项目中带来了这种依赖关系,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,因为我尝试使它起作用的原因有所不同：
<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>
>已验证连接数据(URL,用户和密码),并且对于我尝试连接的每个环境数据库来说都是正确的.
>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,我也可以看到它：[DEBUG]将项目依赖项：ojdbc14添加到classpath
>我可以在jar中看到类oracle.jdbc.driver.OracleDriver.
但是,我每次都会遇到这些错误：
>使用class =“ org.apache.commons.dbcp.BasicDataSource”作为dataSource类时：
class =“ org.apache.commons.dbcp.BasicDataSource”

尽管我不知道为什么,但是在这两条消息中,它显然都无法加载OracleDriver.第一个表示ClassNotfoundException,第二个表示java.lang.IllegalStateException.
现在,我正在Eclipse中使用maven插件运行,为了以防万一,但为了知道这不是在Maven上运行时的解决方案,我尝试将ojdbc jar添加到eclipse类路径中.但是没有任何效果. oracle驱动程序版本对于我们的Orcale是正确的,URL是正确的,因此用户名和密码都试图指向我可以访问的每个环境db(本地,dev,qa,暂存).没事.
任何人都知道为什么实际上将jar添加到类路径时为什么找不到或加载OracleDriver吗？
解决方法:
您是否正在应用服务器上运行此应用？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驱动程序依赖关系的默认值(编译),因为它是默认值,您可以省略scope标签：
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.2</version>
</dependency>
两个范围之间的区别：
>编译
这是默认范围,如果未指定则使用.编译依赖项在项目的所有类路径中均可用.此外,这些依赖项会传播到相关项目.
>提供
这很像编译,但是表明您希望JDK或容器在运行时提供依赖项.例如,在为Java Enterprise Edition构建Web应用程序时,您将对Servlet API和相关Java EE API的依赖关系设置为提供的范围,因为Web容器提供了这些类.该作用域仅在编译和测试类路径上可用,并且不可传递.
