Maven 过滤不适用于 pom.xml 中的属性

Question

我正在尝试配置我的 pom.xml 文件以替换 Spring 配置文件中的占位符。

这是我的 pom.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                    <showDeprecation>true</showDeprecation>
                </configuration>
            </plugin>
            <plugin>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

这是我的 Spring 配置文件（*path : /src/main/webapp/WEB-INF/spring/application-context-infrastructure-env.xml）：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- ${env} is a variable that is replaced at build time by Maven (see pom.xml).-->
<import resource="infrastructure/${env}/application-context-${env}-infrastructure.xml"/>

</beans>

但是当我尝试在 mvn clean install 之后启动我的应用程序时，我得到了这个：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [application-context-infrastructure-env.xml]
Offending resource: ServletContext resource [/WEB-INF/spring/application-context.xml]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/spring/application-context-infrastructure-env.xml]; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'env'

当我查看目标目录中的 application-context-infrastructure-env.xml 时，没有任何变化。我有 ${env} 占位符。

我认为我的 Maven 过滤无法正常工作。你能帮我解决这个问题吗？

我认为你必须使用maven-war-plugin。

我的一个项目的示例配置：

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.5</version>
        <configuration>
            <filteringDeploymentDescriptors>true</filteringDeploymentDescriptors>
            <webResources>
                <resource>
                    <directory>src/main/webapp</directory>
                    <includes>
                        <include>**/*.html</include>
                    </includes>
                    <filtering>true</filtering>
                </resource>
                <resource>
                    <directory>src/main/webapp/META-INF</directory>
                    <targetPath>/META-INF</targetPath>
                    <filtering>true</filtering>
                </resource>

            </webResources>

        </configuration>
    </plugin>

只需调整<directory> 元素。
