java - @autowired 在 Spring Boot 最新版本中使用 jdbctemplate 的问题

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>
        <relativePath/>
      </parent>
    <dependencies>

                 <artifactId>spring-boot-starter-jdbc</artifactId>
            </dependency> 

            <dependency>
                <groupId>org.codehaus.jettison</groupId>
                <artifactId>jettison</artifactId>
                <version>1.4.0</version>
            </dependency>

      </dependencies>

我使用 eclipse 创建了新的 maven + Spring boot 和最新版本的项目。但尝试 Autowiring JdbcTemplate 时出现以下错误。我在上面分享了我的属性文件和 pom.xml。

    Error::
    org.springframework.beans.factory.UnsatisfiedDependencyException:

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，没有包含 Oracle 驱动程序 JAR 的公共(public)存储库。尝试将其添加到您的 pom 中 this answer .
