9.11. Spring boot with Oracle

9.11.1. Maven

首先到oracle官网，根据你的Oracle数据库，下载ojdbc6.jar(Oracle 11) 或者 ojdbc7.jar (Oracle 12)

        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc7</artifactId>
            <version>12.1.0.1</version>
        </dependency>			
mvn install:install-file -Dfile=ojdbc7.jar  -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0.1 -Dpackaging=jar

另一种方案是在项目根目录下创建一个/lib文件夹，将下载的驱动放入该文件夹中。然后pom.xml 加入下面代码

ojdbc6.jar 例子

        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.3</version>
            <scope>system</scope>
            <systemPath>${basedir}/lib/ojdbc6.jar</systemPath>
        </dependency>

ojdbc7.jar 例子

        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc7</artifactId>
            <version>12.1.0.1</version>
            <scope>system</scope>
            <systemPath>${basedir}/lib/ojdbc7.jar</systemPath>
        </dependency>
