spring-boot - Spring Boot : error when add spring-boot-starter-data-jpa dependency

Question

当我在 pom.xml 中添加简单的 spring-boot-starter-data-jpa 依赖项时，在 pom.xml 文件中出现错误。如果我删除该依赖项，则不会再有错误。我不确定为什么会发生这种情况，因为我正在尝试执行一个简单的 jpa 示例。如果我添加其他 starter 依赖项，我没有问题，我只有那个特定的 starter 有问题。

我正在使用 Spring STS 3.7.0 来开发我的测试。
我使用 jdk 8.0.0.60

感谢您的帮助。

Answer 1

运行 Spring Boot 应用程序时，Eclipse IDE 中的 Maven 配置可能配置错误。为了解决这个问题，您需要提供更多关于您的设置的信息，或者您可以从命令行使用 Maven 来获取更多信息。

从终端，导航到您的目录 pom.xml文件。然后运行以下命令。

$ mvn clean install

请注意输出，如果构建成功，您可以使用 Maven spring-boot 插件来运行应用程序。使用以下 Maven 命令:

$ mvn spring-boot:run
