Maven全新安裝構建失敗：Spring Boot- MVC，JPA

Question

我目前正在嘗試從我的Spring啟動項目中發動戰爭。 我的項目主要是一個使用JPA持久化到DB2的MVC應用程序（這是一個項目需求）。

為了持久性，我使用從Spring的CRUDRepository類擴展的repo接口。

我正在使用Eclipse進行開發，並且構建很好：我能夠使用Eclipse啟動並運行我的項目，並使用localhost進行測試。 一切都已自動接線並正確設置。 但是，我正在嘗試使用maven全新安裝進行構建以產生戰爭。

我認為問題主要出在JPA回購協議的自動裝配上。

我要這樣做正確嗎？ 我應該首先使用Maven進行構建嗎？ 我應該考慮我的未來嗎？

好的，這是我的文件：

的pom.xml

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

Application.properties：

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全新安裝控制台輸出 ：

抱歉，控制台文件很大，我不想在這里出現一個史詩般的傳奇故事。

您的項目中缺少DB2驅動程序依賴性，您可以在日志中看到它：

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

您需要將jar放在某個地方（很可能是IBM網站...，我懷疑它在maven中央），然后將其本地安裝到存儲庫中並添加到pom中。
