这期内容当中小编将会给大家带来有关如何在SpringBoot项目中使用Oracle11g数据库，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。
1：下载ojdbc6.jar ,随便放个英文目录位置就好
2：命令行下输入下行，注意最后-Dfile 为自己的下载目录
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=H:\eclpise-workspace\ojdbc6.jar
3：在项目的pom文件中引入下面依赖
<dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.1.0</version> </dependency>
4：在项目的配置文件中写数据库的连接信息，其中，假设Oracle连接ip为127.0.0.1，端口号为1521，数据库为database，用户名为username，密码为password
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver spring.datasource.url=jdbc:oracle:thin:@127.0.0.1:1521:database spring.datasource.username=username spring.datasource.password=password
完成！
| 驱动 | oracle.jdbc.driver.OracleDriver |
| 连接Url | jdbc:oracle:thin:@192.168.112.129:1521:orcl |
| 用户 | System |
| 密码 | Aa123456 |
这里添加的是ojdbc6包，因为之前在Davinci系统使用ojdbc14时报错了，我使用的Jdk1.8的版本。
ojdbc6.jar比ojdbc14.jar的版本高得多，因为里面的6是指支持jdk1.6 ，而14是指支持jdk1.4。
<dependency> <groupId>com.oracle.database.jdbc</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.4</version> </dependency>

经查询，在初始化OracleJdbcSqlTemplate时，由于SpringBoot2.0中使用的是Spring-jdbc-5.0.4，出现了上面的报错信息。
该代码之前使用spring4的spring-jdbc.jar就不会报错，因为spring 5之后就不存在OracleLobHandler这个类了。
由于不想修改代码，继续沿用老版本:
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.2.6.RELEASE</version> </dependency>
