Question

下面是我的application.properties文件

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@abc:1512:dbq
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=update

下面是我的POM.xml

      <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>

我使用eclipse用最新版本的项目创建了新的maven + Spring引导。但是当尝试自动连接JdbcTemplate时遇到错误。我在上面共享了我的属性文件和pom.xml。

Answer 1

您缺少Oracle数据库的jdbc驱动程序。

不幸的是，由于二进制许可证，Oracle Driver JAR没有公共存储库。尝试将其添加到this answer之后的pom中。

Answer 2

我添加此代码是为了展示在jar应用中存储spring-boot的另一种方法。这样，如果新开发人员拉出该应用程序，他/她将无需遵循this的方式。

在lib内创建目录src：src/lib/

然后将您的ojdbc-{versio}.jar放在lib文件夹中，然后将此依赖项添加到gradle中：

compile files('src/lib/ojdbc8-{version}.jar')

对于maven，添加此依赖项：

<dependency>
groupId ...
artifactId ...
version ...
<scope>system</scope
<systemPath>${project.basedir}/src/main/resources/yourJar.jar</systemPath>
</dependency>
