问题描述
使用:生命射线6.1春天3.1spring-portlet-mvc
using:liferay 6.1spring 3.1spring-portlet-mvc
我们尝试使用@Autowired注入弹簧豆，看来这不适用于liferay 6.1吗?已知的错误?解决方法?
We tried to inject spring beans with @Autowired and it seems that this doesnt work with liferay 6.1 ? Known bug? Workaround?

推荐答案
问题与您的web.xml文件有关.您需要做的是添加以下侦听器:
The problem is related to your web.xml file. What you need to do is add the following listener:
<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( LPS-29103 )存在一个错误.如果您使用Liferay自动部署过程，则会出现此问题，此修复程序已经发布.由于自动部署过程会修改web.xml文件并将侦听器按不正确的顺序放置，因此导致出现此问题.
Note there is a bug with Liferay 6.1 and custom spring-mvc portlet deployments (LPS-29103). The problem occurs if you use the Liferay auto-deploy process, a fix has already been released. The issue results because the auto-deploy process amends the web.xml file and sticks the listener in the incorrect order.
您需要做的是在spring上下文侦听器之后添加侦听器(SecurePluginContextListener).因此，在您的情况下，它将是:
What you need to do is add the listener (SecurePluginContextListener) after your spring context listener. So in your case it would be:
<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>
希望这可以解决您的问题.
Hope this resolves your issue.
