打包時Hibernate無法加載類，但可以在IDE

當我在Intellij中運行我的程序時，它工作正常。 Maven將其打包完美令人高興的是，它還將推出精，但只要我嘗試從休眠數據庫中檢索任何東西，我得到以下錯誤：打包時Hibernate無法加載類，但可以在IDE

我的問題似乎幾乎相同this question here，但這個問題沒有答案，這實際上是我在搜索錯誤時出現的一件事。我和他在這個帖子上提出的問題有同樣的答案。

好像相關的一部分 - 程序會運行，如果我從我的POM文件中刪除log4j的依賴Hibernate不抱怨 - 雖然記錄不會明顯抱怨。

我已經包括了我的POM文件：

需要明確的是，我刪除以下依存關係到它的工作：

<dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-api</artifactId> 
     <version>2.7</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.logging.log4j</groupId> 
     <artifactId>log4j-core</artifactId> 
     <version>2.7</version> 
    </dependency>

希望你能幫助 - 我在完全喪失。

未找到的類是jackson ObjectMapper。在POM爲log4j-core（V 2.7），這可以發現：

<!-- Required for JSON support --> 
<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-core</artifactId> 
    <optional>true</optional> 
</dependency> 
<!-- Required for JSON support --> 
<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-databind</artifactId> 
    <optional>true</optional> 
</dependency>

可選的標誌意味着這些不包括作爲傳遞依賴。將它們添加到你的pom（可選標誌不需要），它應該工作。

至於爲什麼它工作在IDEA，它可能是依賴包含在其他模塊（IDEA項目有1級扁平的classpath，內置的文件各有一個）。或者，一些配置是不同的，這樣的JSON支持從IDEA運行時不需要。
