我正在尝试合并两个战争，从而使用 maven uber war cargo-maven2-plugin 合并 web.xml 文件。所有标签（过滤器，servlet）的合并都按需要进行，但因为<context-param>它只合并 RHS 上 web.xml 中定义的第一个元素，我想保留 LHS 上 web.xml 上的所有上下文参数合并所有<context.param>元素在我的 RHS 上的 web.xml 中定义任何帮助将不胜感激。这是我的代码

RHS 上的 web.xml

    <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>

好吧，在这种特殊情况下的问题是 xmlns 版本的差异，以及 web.xml 顶部的模式位置。第一场战争的版本=2.4，而第二场战争的版本=3.0。通过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 标记，但是在合并所有上下文参数标记时失败了）。

<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">
