如何在Liferay ext-plugin中覆盖Portal-Impl jar类 [英] How to override portal-impl jar classes in Liferay ext-plugin

问题描述

我想覆盖两个portal-impl.jar类 NtlmFiler.java 和 NtlmPostFilter.java ，我创建了一个ext-plugin项目并放置了自定义的书面类在ext-impl/src中，但是我无法将spring.xml文件配置为使用新编写的类而不是portal-impl类，也许我完全不赞成这样做.

I want to override two portal-impl.jar classes NtlmFiler.java and NtlmPostFilter.java, I have created an ext-plugin project and placed my custom written classes in ext-impl/src but I am unable to configure my spring.xml file to use my newly written classes instead of portal-impl classes, maybe i am totally wrong about doing it this way.

我的ext-spring.xml代码是:

My ext-spring.xml code is :

<?xml version="1.0" encoding="UTF-8"?>
<beans>
<bean id="com.liferay.portal.servlet.filters.sso.ntlm.NtlmFilter"
    class="com.liferay.portal.servlet.filters.sso.ntlm.NtlmFilter">
    <property name="ntlmFilter">
        <bean class="com.sso.ntlm.filter.CustomNtlmFilter">
            <property name="CustomNtlmFilter" ref="customNtlmFilter" />
        </bean>
    </property>
</bean>
<bean id="com.liferay.portal.servlet.filters.sso.ntlm.NtlmPostFilter"
    class="com.liferay.portal.servlet.filters.sso.ntlm.NtlmPostFilter">
    <property name="ntlmPostFilter">
        <bean class="com.sso.ntlm.filter.CustomNtlmPostFilter">
            <property name="CustomNtlmPostFilter" ref="customNtlmPostFilter" />
        </bean>
    </property>
</bean>

注意:该想法是解决这个问题

推荐答案

由于NtlmFilter不是Spring bean，因此在ext-spring.xml中没有用它来定义它.

As the NtlmFilter is no Spring bean, there is no use to define it in ext-spring.xml.

请参见portal.properties:

# ... and the filter
# com.liferay.portal.servlet.filters.sso.ntlm.NtlmFilter must be referenced
# in web.xml.

因此，您只需要在liferay-web.xml或web-ext.xml中引用过滤器类即可(我不知道后者是否适用于覆盖).

So you just need to reference your filter class instead in liferay-web.xml or web-ext.xml (I don't know if the later works for overrides).

NtlmPostFilter也是如此.
