是否可以在maven中设置一个可以从java类中获得的系统属性。
我已经看到这在surefire插件中是可能的（这里），如下所示；
String param = System.getProperty("my_parameter1");
<configuration>
<systemPropertyVariables>
<my_property1>${my_property1}</my_property1>
</systemPropertyVariables>
</configuration>
然而，我想得到一个处理我正在工作的环境，我已经通过prod或dev作为maven配置文件参数-是否有可能以某种方式在代码中获得一个句柄，或者从设置一个变量在配置文件中我调用，然后调用system. getProperty或其他方式？
谢啦
我的pom文件

您应该查看exec-maven-plugin。
使用以下配置（注意
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.3.2</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
<configuration>
<mainClass>com.example.Main</mainClass>
<arguments>
<argument>argument1</argument>
</arguments>
<systemProperties>
<systemProperty>
<key>hello.world</key>
<value>Hello Stack Overflow!</value>
</systemProperty>
</systemProperties>
</configuration>
</plugin>
…和下面的班级…
package com.example;
public class Main {
public static void main(String[] args) {
String prop = System.getProperty("hello.world");
System.out.println(prop);
}
}
…并运行一个包（注意配置中的阶段-您可以根据需要进行更改，也许是安装），它会从键hello.world打印出值Hello Stack Overflow！。所以基本上，插件在您构建时执行您的程序。
另请参阅exec： exec目标。在示例中，我使用了exec：java目标，但两者的功能不同。
exec： exec在单独的进程中执行程序和Java程序。
exec： java在同一个VM执行Java程序。

目前，我正在根据我的maven pom文件中的配置文件设置属性中的一些值。是否可以在配置文件中设置此系统属性？因为真的，我只有一个用于dev和prod的pom文件，它在配置文件中，我需要设置它。
是的，只需使用中的${property.name}
<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<id>world</id>
<properties>
<hello.world>Hello World!</hello.world>
</properties>
</profile>
<profile>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<id>stack</id>
<properties>
<hello.world>Hello Stack Overflow</hello.world>
</properties>
</profile>
</profiles>
和插件
<systemProperties>
<systemProperty>
<key>hello.world</key>
<value>${hello.world}</value>
</systemProperty>
</systemProperties>
只需将配置文件更改为堆栈或world，消息将分别打印Hello Stack Overflow或Hello World。
更新2
另一个插件是states-maven-plugin。有一段时间没有对其进行任何操作，但通过一些测试，必要的功能已经存在。
它有一个set-system-properties目标以及一些其他有用的目标来帮助简化属性管理
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
<executions>
<execution>
<!-- any phase before your app deploys -->
<phase>prepare-package</phase>
<goals>
<goal>set-system-properties</goal>
</goals>
<configuration>
<properties>
<property>
<name>hello.world.two</name>
<value>Hello World!</value>
</property>
</properties>
</configuration>
</execution>
</executions>
</plugin>
