拋出java.lang.ClassNotFoundException：org.apache.pdfbox.exceptions.COSVisitorException

我的項目進行工作之前，我不得不重新安裝操作系統相當精細，現在它給了我這個巨大的例外：拋出java.lang.ClassNotFoundException：org.apache.pdfbox.exceptions.COSVisitorException

我有之前使用Eclipse，然後IntelliJ，但得到了同樣的問題... 我使用Java 8和Apache Tomcat 7.0.73。曾經有一段時間它開始正確，但我無法像瀏覽器之前那樣在瀏覽器中訪問它（實際上我無法訪問）。

升級您的託管和項目相關庫（apache pdf） –

我意識到，錯誤實際上是一個沒有被發現的類（這是我收到NoClassDefFoundError的原因），所以我將我的pdfbox maven依賴項更新爲2.0.7版。做到這一點我仍然有同樣的錯誤，然後我只是發現了未滿足的類在哪裏，IntelliJ本身也提供了正確的類，我認爲我需要這樣做，也許是因爲它在更新後發生了變化，或者我沒有知道它到底如何。我相信，Eclipse以某種方式運行它，即使運行編譯器錯誤，IntelliJ也需要我修復這些錯誤。

通常NoClassDefFoundError告訴你，你沒有包含必要的類的jar文件。在你的情況下，這是COSVisitorException。在這裏你有兩個選擇。

添加行家依賴於你的項目：

<dependency> 
    <groupId>org.apache.pdfbox</groupId> 
    <artifactId>pdfbox</artifactId> 
    <version><!--specify version which you are using --></version> 
</dependency>

或下載PDFBOX的版本 - 從maven repository ***罐子，並添加到您％TOMCAT_HOME％/ lib目錄

當前1.8版本是1.8.13時，爲什麼他應該使用1.8.2（包含已知的安全風險）？ –

@TilmanHausherr這只是一個例子。因爲版本在問題中未知。但是我已經更新了我的答案，所以FtheBuilder可以自己選擇使用哪個版本。無論如何感謝您的評論。 –

謝謝@MikitaBerazouski這個答案。我已經擁有了它，但是我將版本更改爲1.8.13，但它仍然不起作用，給出同樣的解決方案'NoClassDefFoundError' – FtheBuilder

拋出java.lang.ClassNotFoundException：org.apache.pdfbox.exceptions.COSVisitorException
