Spring JDBC Could not load JDBC driver class [orac

问题:

I wonder if any one could help me with this. I encountered an issue when I tried writing code with Spring JDBC. When I ran the server, I got the message like I mentioned in the title. I have google it and someone said that you should import ojdbc.jar. However, I have already imported it. Here comes my code:

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
    <property name="url" value="jdbc:oracle:thin:@192.168.0.13:1521/orcl" />
    <property name="username" value="Hibernate" />
    <property name="password" value="123456" />
    </bean>

</beans>

Please kindly suggest if I have done something wrong. Many thanks in advance.

Make sure that you have ojdbc.jar gets added into your class path. If you want, you can also double check it by opening .classpath file and look for ojdbc.jar entry. If you don't have it, download it from the the maven repo as mentioned below:

        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.3</version>
        </dependency>
.......

    <repositories>
        <repository>
            <id>codelds</id>
            <url>https://code.lds.org/nexus/content/groups/main-repo</url>
        </repository>
    </repositories>

Download the ojdbc jar from here

put ojdb6.jar in some folder in your project (let's use lib).

<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc</artifactId>
<version>11.2.0</version>
<scope>system</scope>
<systemPath>${basedir}/lib/ojdbc6.jar</systemPath>

Then do mvn install:install-file -Dfile=path/to/ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

I just put ojdbc6.jar in apache tom cat installation directory in lib directory

D:\TOOLS\apache tomcat server\Tomcat 8.0\lib

It solved my problem.

Try

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
    <property name="url" value="jdbc:oracle:thin:schema_name/123456@192.168.0.13:1521:orcl" />
    <property name="username" value="Hibernate" />
    <property name="password" value="123456" />
    </bean>

</beans>

If you use Spring Boot 2 (I am using Spring Boot 2.0.4.RELEASE, Oracle database 12c), application.properties

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:schema_name/123456@192.168.0.13:1521:xe
spring.datasource.username=Hibernate
spring.datasource.password=123456

(You must have ojdbc7.jar in classpath)

In my case the problem was setting the scope to runtime:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>7.0.0.jre8</version>
    <scope>runtime</scope>
</dependency>
