spring - Liferay + Spring + Spring Web Mvc - @Autowired 不起作用

Question

使用:生命射线6.1 Spring 3.1spring-portlet-mvc

我们尝试使用 @Autowired 注入(inject) spring beans，但似乎这不适用于 liferay 6.1？已知错误？解决办法？

这里是我的applicationContext.xml:

Answer 1

问题与您的 web.xml 文件有关。您需要做的是添加以下监听器:

<listener-class>com.liferay.portal.kernel.servlet.SecurePluginContextListener</listener-class>

请注意，Liferay 6.1 和自定义 spring-mvc portlet 部署存在一个错误 ( LPS-29103 )。如果您使用 Liferay 自动部署过程，就会出现此问题，修复程序已经发布。导致此问题的原因是自动部署过程修改了 web.xml 文件并将监听器固定在错误的顺序中。

您需要做的是在 Spring 上下文监听器之后添加监听器 (SecurePluginContextListener)。所以在你的情况下它将是:

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
    <listener-class>com.liferay.portal.kernel.servlet.SecurePluginContextListener</listener-class>
</listener>
<listener>
    <listener-class>com.liferay.portal.kernel.servlet.PortletContextListener</listener-class>
</listener>

希望这能解决您的问题。
