【问题描述】：

我的应用程序使用许多数据源（postgreSQL、Sybase） 我尝试添加一个 Oracle 数据源

Application.properties

rocbis.datasource.prd.driver.class-name=oracle.jdbc.driver.OracleDriver
rocbis.datasource.prd.jdbc-url=jdbc:oracle:thin:@<host>:1521:<dbname>
rocbis.datasource.prd.username=<username>
rocbis.datasource.prd.password=<password>

主机、数据库名、用户名和密码已被混淆...

配置类

@Bean(name = "rocbisDatasourcePRD")
@ConfigurationProperties(prefix = "rocbis.datasource.prd")
public DataSource rocbisDataSourcePRD() 
    return DataSourceBuilder.create().build();


@Bean(name = "rocbisJDBCTemplatePRD")
public JdbcTemplate rocbisJdbcTemplatePRD(@Qualifier("rocbisDatasourcePRD") DataSource ds) 
    return new JdbcTemplate(ds);

和 POM.xml

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>19.6.0.0</version>
</dependency>
<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ucp</artifactId>
    <version>19.6.0.0</version>
</dependency>

当 Springboot 启动时出现以下错误：

Caused by: java.lang.RuntimeException: Failed to get driver instance
for jdbcUrl=jdbc:oracle:thin:@<host>:1521:<dbname> at com.zaxxer.hikari.util.DriverDataSource.<init>DriverDataSource.java:112)

我试过了：

driver-class-name 而不是 driver.class-name

oracle.jdbc.driver.OracleDriver 代替 oracle.jdbc.OracleDriver

有什么想法吗？ 谢谢

【参考方案1】：

使用oracle.jdbc.OracleDriver 而不是oracle.jdbc.driver.OracleDriver

以下配置适用于我的 Oracle

pom.xml

<dependency>
    <groupId>com.oracle.ojdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>19.3.0.0</version>
</dependency>

bootstrap.properties

spring.datasource.url=jdbc:oracle:thin:@<host>:<port>:<service>
spring.datasource.username=<username>
spring.datasource.password=<password>
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
