2.24. Spring boot with Oracle

2.24.1. Maven

首先到oracle官網，根據你的Oracle資料庫，下載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 -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -Dfile=ojdbc6.jar -DgeneratePom=true
			mvn install:install-file -Dfile=ojdbc7.jar -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0.1 -Dpackaging=jar

另一種方案是在項目根目錄下創建一個/lib檔案夾，將下載的驅動放入該檔案夾中。然後pom.xml 加入下面代碼

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>
