我有一个使用 Hibernate 的 Maven 构建的 Web 应用程序。它在 Tomcat 中成功运行，但在 Tomcat 中执行时失败并出现以下异常jetty-maven-plugin：

org.hibernate.collection.PersistentCollectionis in hibernate-core，它作为对 Web 应用程序的传递依赖项包含在内。它绝对可以在 WAR 中访问，因为应用程序在放入 Tomcat 时可以正常运行。

POM 包含以下插件配置：

<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>8.1.3.v20120416</version>

    <configuration>
        <jettyXml>src/main/jetty/jetty-env.xml</jettyXml>
    </configuration>

    <dependencies>
        <dependency>
            <groupId>c3p0</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.1.2</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.9</version>
        </dependency>
    </dependencies>
</plugin>

为什么jetty-maven-plugin没有解决org.hibernate.collection.PersistentCollection？

事实证明这是 Spring Flex 和 Hibernate 4 之间的不兼容：https ://jira.springsource.org/browse/FLEX-220 。
