Maven Uber War (Cargo-Maven2-plugin) 只合并第一个<context-param>元素

Question

我正在尝试使用 maven uber war cargo-maven2-plugin 合并两场战争，从而合并网络.xml文件。所有标签（过滤器、servlet）上的合并都按预期进行，但<context-param>它只是合并 Web 中定义的第一个元素.xml在 R.H.S 上。我想保留网络上的所有上下文参数.xml在 L.H.S 上合并我网站上定义的所有<context.param>元素.xml在 R.H.S 上。任何帮助将不胜感激。这是我的代码

网站.xml在R.H.S上

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- ** SPRING ** -->
    <context-param>
        <param-name>contextInitializerClasses</param-name>
        <param-value>com.myorg.context.MyApplicationContextInitializer</param-value>
    </context-param>
   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:conf/spring/*.xml</param-value>
    </context-param>
   <context-param>
        <description>Location(s) to search for the Log4J config file</description>
        <param-name>log4jConfigLocation</param-name>
        <param-value>file:/dir/path/log4j.xml /WEB-INF/log4j.xml</param-value>
    </context-param>
    <context-param>
        <description>
            Boolean flag indicating whether internal Log4J debugging statements should be written. Log4J
            will write debugging messages to System.out and error messages to System.err.
        </description>
        <param-name>log4jConfigDebug</param-name>
        <param-value>false</param-value>
    </context-param>

Answer 1

嗯，在这种特殊情况下，问题是 xmlns 版本的差异，以及 web.xml 顶部的架构位置。第一次战争的版本=2.4，而第二场战争的版本=3.0。使用以下方法使两个 web.xml 模式保持同步解决了这个问题（我不知道为什么它合并了过滤器、servlet 标签，并且在合并所有上下文参数标签时失败了）。

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="3.0" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
