java.lang.IncompatibleClassChangeError：實現類Mongo

我無法弄清爲什麼我得到這個錯誤。我試圖清理冗餘的庫，等等。java.lang.IncompatibleClassChangeError：實現類Mongo

我得到的錯誤，當我嘗試做：

mongo = new Mongo(host, port);

有趣的是，我可以運行任何單元測試，我從IDE（的IntelliJ）製成，但是當我試圖通過Tomcat的我運行得到這樣的：

通常，該錯誤是由於使用一組JAR文件編譯並針對不同的集合運行所致。它可以是您的班級或您使用的其中一個JAR中的某個班級。不幸的是，它似乎沒有告訴我們哪個班級發生了錯誤。 –

@HotLicks，實際上它說哪個類發生錯誤：'at com.mongodb.MongoOptions.reset（MongoOptions.java:47） ' – sfat

不，這就是發生錯誤的地方。但是錯誤發生在正在加載的類上，無論如何。如果你可以在那個時候檢查代碼，你可能會破譯正在加載的類。 –

這看起來像是字節代碼級別的錯誤。也許你在你的tomcat服務器上有兩個版本的同一個庫。

似乎'mongo-java-driver'裏面有一個使用org.bson的類，我添加了自己的'bson'依賴項，這是干擾 – sfat

如果你的JBoss下這個問題，這是最有可能的原因在於JBoss的捆綁RestEasy的REST實現爲默認的事實。如果您將自己的REST庫打包爲EAR/WAR文件，則需要禁用部署庫的默認RESTeasy才能工作。
