Maven过滤不适用于pom.xml中的属性 [英] Maven filtering doesn't work with properties in pom.xml

问题描述

我正在尝试配置pom.xml文件，以便替换Spring配置文件中的占位符.

I am trying to configure my pom.xml file in order to replace placeolders in a configuration file for Spring.

这是我的pom.xml:

Here is my pom.xml :

<?xml version="1.0" encoding="UTF-8"?>

                </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):

Here is my Spring configuration file (*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>

但是当我尝试在执行mvn全新安装后启动我的应用程序时，我得到了:

But when I try to launch my application after a mvn clean install, I get this :

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，没有任何改变.我有$ {env}占位符.

And when I look at my application-context-infrastructure-env.xml in the target directory, nothing have changed. I have the ${env} placeholder.

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?

I think my maven filtering doesn't work correctly. Could you help me to fix this ?

推荐答案

我认为您必须使用 maven-war-plugin .

我的一个项目的示例配置:

Example configuration from one of my projects:

    <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.
