我需要通过外部属性文件中pom.xml
的密钥获取价值。属性文件的位置在src/main/resources/dev.properties
中。
我试图通过使用maven中的属性来解决这个问题。请帮我。
pom.xml中:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</project>
// properties File
dev.properties:
projectPath=/home/user/warfile
Project.Name = newProject
Thanks & Regards,

您必须使用属性插件:
<强>插件强>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0.0</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>read-project-properties</goal>
</goals>
<configuration>
<files>
<file>${basedir}/${propertiesFile}</file>
</files>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
Mvn Command
mvn -DpropertiesFile=dev.properties properties:read-project-properties clean install
<强>替代地强>
您可以对文件进行硬编码:
<file>${basedir}/dev.properties</file>

首先,在pom.xml中定义properties标记并启用资源过滤(在build标记下),
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>Simple_project</groupId>
<artifactId>Project</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>Project Maven Webapp</name>
<url>http://maven.apache.org</url>
<properties>
<Project.Name>My-Project-Name</Project.Name>
<path>/home/user/warfile</path>
</properties>
<dependencies>
.....
</dependencies>
......
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
</build>
........
假设您的dev.properties文件位于“ src / main / resources”文件夹下,则将dev.properties文件更新为;
projectPath=${path}
Project.Name=${Project.Name}
project.name=${project.name}
maven构建后,dev.properties的内容将如下:
projectPath=/home/user/warfile
Project.Name=My-Project-Name
project.name=Project Maven Webapp
但是,如果使用的是Spring Boot(最新版本),则需要更新dev.properties文件,例如:
(使用@@标记代替$ {}标记)
projectPath=@path@
Project.Name=@Project.Name@
project.name=@project.name@
在构建Maven之后将产生相同的内容,例如:
projectPath=/home/user/warfile
Project.Name=My-Project-Name
project.name=Project Maven Webapp
