引起者：java. lang.ClassNotFoundException：org.dom4j.io.STAXEventReader


我正在开发一个Web服务应用程序，但由于以下错误，session sionFactory bean没有创建。我看不到dom4jjar的重复或冲突版本。我多次尝试在eclipse中引用/清理服务器和项目。

Hibernate版本5.1.0.Final

我完全被困住了。你们中有人知道如何解决这个问题吗？？

感谢Hohenheim指出版本问题。

hibernate core5.1.0.Final包含dom4j-1.6.1jar会引发此错误。要解决此问题，需要从hibernate-core中排除dom4j-1.6.1并将dom4j-1.6包含在pom中。

我找不到发生这种情况的确切原因。

这就是我在Hibernate依赖中从pom中排除dom4j的方式。

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.1.0.Final</version>
    <exclusions>
        <exclusion>
            <artifactId>jta</artifactId>
            <groupId>javax.transaction</groupId>
        </exclusion>
        <!-- Exclude SLF4j to avoid version conflicts (we have 1.6.6, this drags 
                in 1.6.1) -->
        <exclusion>
            <groupId>org.slf4j</groupId>

        <!-- Exclude dom4j to avoid version conflicts (we have 1.6, this drags

        <exclusion>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>

我使用了Ivy依赖管理器，在我的例子中，我从核心依赖中删除了dom4j，并再次添加了最后一个版本1.6.1，这对我有用。 

<dependency org="org.hibernate" name="hibernate-core" rev="5.2.8.Final">
    <exclude  org="dom4j"/>
</dependency>

<dependency org="dom4j" name="dom4j" rev="1.6.1"/>

在我遇到同样问题的情况下，我解决了在pom. xml中设置此版本的问题：

  • Spring版本4.3.7。释放
  • Hibernate版本4.1.9.Final

我没有使用

<dependency>
    <groupId>dom4j</groupId>
    <artifactId>dom4j</artifactId>
    <version>1.4</version>
</dependency>
