如何在我的 liferay portlet 中使用 spring jars 而不是 ROOT\WEB-INF\lib 中的 spring jars？

Question

我创建了一个 portlet，并尝试在其中使用 spring jpa 进行数据检索。我正在使用 Spring 版本 3.2.14，并且我需要的 spring jar 部署在我的 portlet 的 WEB-INF/lib 文件夹中。

在启动 tomcat 时，我不断收到以下异常：

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'packagesToScan' of bean class [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Bean property 'packagesToScan' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

如果我将调试器附加到 Tomcat，我可以看到它使用的是 ROOT/WEB-INF/lib 中的 spring-beans.jar（版本 3.0.7.RELEASE），它在 'packageToScan' 中存在已知问题我的 bean 定义中的 LocalContainerEntityManagerFactoryBean：

<bean id="reportingEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan">
        <list>
            <value>org.preptoolkit.exercise.reporting.model</value>
        </list>     
    </property>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true" />
            <property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect"/>
        </bean>
    </property>
</bean>

我已经尝试将 spring-beans-3.2.14.RELEASE.jar 放入 $tomcat_home/lib/ext 并且 liferay 仍然使用 3.0.7 版本。

Liferay 版本：6.2-ce-ga4

那么如何让 Liferay 使用 spring-beans-3.2.14.RELEASE.jar 而不是我的 portlet 的一个 ROOT？

（我已经在这堵墙上敲了 3 天）

这是完整的堆栈跟踪：

有一个SpringHotDeployListener 尝试为每个 portlet 应用程序初始化 Spring（使用 Liferay 的库）。

要为您的 web 应用关闭此功能，您必须删除 portal-ext.properties 中属性 hot.deploy.listeners 中的 com.liferay.portal.deploy.hot.SpringHotDeployListener。

如果您使用其他使用 Liferay Spring 环境的 portlet 应用程序，您需要创建一个 Ext Plugin 并在 ext-impl 中扩展 SpringHotDeployListener ：

public class MySpringHotDeployListener extends SpringHotDeployListener {
    protected void doInvokeDeploy(HotDeployEvent hotDeployEvent) throws Exception {
        if (!hotDeployEvent.getServletContext().getServletContextName().equals("MyContextName")) {
            super.doInvokeDeploy(hotDeployEvent);
        }
    }

    // Same for doInvokeUndeploy
}

然后在portal-ext.properties 中使用MySpringHotDeployListener 而不是SpringHotDeployListener。
