實體無法轉換爲org.hibernate.proxy.HibernateProxy

在我的pom.xml一些更新後，我開始有一些奇怪的例外。當我使用Jetty Container運行我的應用程序時，纔會出現異常情況。當我運行我的junit測試時，一切都很正常。實體無法轉換爲org.hibernate.proxy.HibernateProxy

我的pom.xml有：

任何人都知道發生了什麼事？我很確定我有一些依賴衝突。但我不知道是什麼依賴性，創建一個不同的Proxy

後我打破了我的項目分爲兩個型動物項目的啓動問題。我的實體類是一種公共資源項目，並負載使用：

<property name="hibernate.ejb.resource_scanner" value="com.leste.hibernate.ResourceScanner"/>

我想，這個問題可以在這裏：

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>${hibernate.version}</version> 
    <exclusions> 
     <exclusion> 
      <artifactId>javassist</artifactId> 
      <groupId>org.javassist</groupId> 
     </exclusion> 
    </exclusions> 
</dependency

請嘗試刪除「exclution」標籤：

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>${hibernate.version}</version> 
</dependency

這不是問題所在。我刪除它，但仍然發生 – Victor

好吧，讓exclution背部和嘗試：

<dependency> 
    <groupId>org.javassist</groupId> 
    <artifactId>javassist</artifactId> 
    <version>3.18.1-GA</version> 
</dependency>

，並嘗試與版本進行試驗。
