java - Maven 全新安装构建失败 : Spring Boot- MVC, JPA

Question

我目前正在尝试从我的 Spring boot 项目构建一场 war 。我的项目主要是一个使用JPA持久化到DB2的MVC应用程序(这是一个项目需求)。

为了持久性，我使用从 Spring 的 CRUDRepository 类扩展的存储库接口(interface)。

我正在使用 Eclipse 进行开发，构建效果很好:我能够使用 Eclipse 启动并运行我的项目，并使用 localhost 进行测试。一切都正在自动连接并正确设置。但是，我正在尝试使用 Maven clean install 进行构建以生成 war 。

我认为问题主要在于 JPA 存储库的 Autowiring 。

我的处理方式正确吗？我应该首先使用 Maven 进行构建吗？我应该考虑一下我的 future 吗？

好的，这是我的文件:

POM.xml

https://www.dropbox.com/s/e1lb4qz1agtcac5/pom.xml?dl=0

应用程序属性:

spring.jpa.hibernate.naming-strategy: org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.database-platform= DB2Platform
#spring.jpa.database-platform: DB2Platform
spring.jpa.show-sql: true
spring.jpa.generate-ddl: true
spring.datasource.driverClassName=com.ibm.db2.jcc.DB2Driver
spring.datasource.url=jdbc:db2:localhost:50000/testing
spring.datasource.username=*A username*
spring.datasource.password=*a password*

Maven clean install console output :

[...]

抱歉，但是控制台文件非常大，我不想在这里出现一个史诗般的问题。

您的项目中缺少 DB2 驱动程序依赖项，您可以在日志中看到它:

Caused by: java.lang.IllegalStateException: Cannot load driver class: com.ibm.db2.jcc.DB2Driver

您需要在某个地方获取 jar(很可能是 IBM 网站...，我怀疑它在 Maven 中心)，然后将其本地安装到您的存储库中并添加到您的 pom 中。
